Title: Watch out for that blower switch, it could fry your car.
Post by: Jon Weywadt on August 14, 2010, 10:52:25 pm
The other day I was driving back from my Dad's house with my daughter as passenger. It was pouring down rain and so the windscreen was beginning to fog up. I turned the blower on high and it ran for a few minutes. Soon I began to smell hot insulation and just as I realized it was coming from inside the car, smoke began to seep out of the dash around the switch. I immediately turned the blower off and kept my hand on the fire extinguisher, just in case. Fortunately the smoke dissipated and no fire erupted.

This just presses the urgency of the modification that Jan and I have been planning. We will install relays and fuses, so the blower gets its power through the relays and not the switch. The switch will only draw the current required to pull the relay, not the 15 amps that the blower draws on full power. Each power setting will have a relay and a fuse.

I hope you all will be paying attention to your own blower switches. I know others have modified this circuit. Perhaps yu can share what and how you did it. I will post photos on this post as the modification comes along.

I think this in an experience all Murena owners at some point will face. I have yet to face this problem, though ;)
Most people just replace the switch - and that's that. I think there was a report of someone here on the forum who fitted relays in the way you're planning, and it's probably a slightly better solution, especially if they're fitted close to the blower so the wiring could be shortened, but for originality and simplicity, you should be fine with a new switch plugged in.

Lennart did a photo series a few years ago documenting the replacement procedure:

The switch lasted 30 years.
The problem occur when the blower motor is asking to much current for some time because of bad bearing.
The switch and wiring around it get overheated and finaly give up.
Since you already adressed the problem of the blower, yo should be fine with a new switch.

Maybe this is a good solution if you plan electronic.
Give the new switch 3 resistors to replace the potmeter.

Edit:
Only 2 resistors are needed because full power doesn't need one.

Hi Oetker.

That is a super solution. I just ordered one, since single speed fans are much easier (and cheaper) to find.

Why not use a single potentiometer instead of the switch? It's a much smoother solution. You only have to source a potentiometer that has the same shaft size as the original switch (otherwise the knob won't fit). Then you will have stepless control of your fan. But fitting a couple of resistors will do the job as well and will keep the outside looking original :)

By the way, my switch was killed by moisture, corrosion and subsequent overheating due to a bad contact area (more resistance, P equals R times I squared...). I had exactly the same experience as the topic starter.

Much too intense currents for a normal potentiometer. And using some resistors may only seem interesting if you like an extra heating in your dashboard, I'm afraid.

Well. Since finding a new motor turned out to be a challenge, I took the old motor apart the other day to see if it could be salvaged. No such luck. One of the windings in the stator has overheated, probably shorted, which explains the smoke coming from the switch. >:(

But today I was in luck. I asked at a garrage, where they sent me to a salvage place (AHKA on Ole Romersvej 16, in 2630 Taastrup, for those of you in Denmark). I brought along the old heater blower and housing. We managed to find one from a Nissan Primera 1995+. It had exactly the same diameter on the blower wheel. It is a one speed, normally using external resistors. However I have bought the electronic motor controller that Oetker pointed me to, so I won't be using the switch, but mount the knob on a 22Kohm potentimeter..

I bought the blower, realizing that it would be a tight fit, as the motor protrudes a couple of centimeters further than the original.

After removing the blower wheel from the new motor (it was oriented to spin the wrong way) I gound a flat surface on the shaft so the original wheel could be mounted (don't push it all the way onto the shaft or it will drag on the motor mount). After testing the motor (4329 rpm at no load), cleaning and lubricating it, I inserted it in the housing and did a test fit in the blower compartment.

It did not fit. >:(

The corner of the inner fender was in the way, but after removing a bit it still would not go into the compartment. The motor was 1+ cm too tall. So, I cut an opening in the back of the motor case (plastic) and found that it did not support the motor in any way. Encouraged, I cut off about 1,5 cm of the housing and sealed the end with duct tape held in place by a strip. Since the shaft stuck out a little bit I placed a plastic cap over it before applying the duct tape. The cap was not tall enough, so I ground off 2 mm of the shaft that stuck out. Success. The fan now slid into the compartment without problem.

One thing to realize is that the new motor assembly does not have holes to allow the air into the Murena housing. I had to cut them with a hole saw, but that was easy.

After mounting the fan and connecting it using the original connector (just two wires, but remember to swap +/- because the motor needs to spin the opposite direction) I jumpered it to the battery. It draws 10,7 amps and creates half a hurricane in the car. ;D ;D ;D

Tomorrow, if I get a potentiometer that fits the dash, I will mount the motor controller and wire it up to the fan.

Pictures below.

I meant to include these photos too, and mention that duct tape is excellent to prevent dust and shavings from entering the motor/bearings while ginding the shaft.

I also forgot to mention that you can screw the new blower onto the housing, using the original holes, (though with screws that are appx. 8mm longer). You can see it on the photo also showing the electronic motor controller. I later decided to add extra screws, making new holes in the blower frame.

Post by: Oetker on September 01, 2010, 09:22:11 am
It takes some effort to accomplish but the result is there.
You measured 11.7 Amp current, so it is possible to go for a smaller module to adjust speed.
The same seller has also 15 Amp modules for half the price, and they are smaller, but I think the 30 Amp module is more robust.
Better ventilation in the Murena is a must, because the original ventilator is in my opinion much to weak.
Good job 8)

Hi Richard.

Unfortunately not. The wheel that came with the blower was meant to turn in the opposite direction. A centrifugal blower wheel must have the cup-side of the squirrel-cage in the direction of the rotation. Otherwise it does not move much air. The original wheel required the flat surface on  the shaft and it was no problem grinding and filing the new shaft to fit.

Okay, i did not think of it that way, in that case i have to change the blower wheels also because i am changing motors also.

The potentiometer that comes with the devise is too small to be used with the original knob. I replaced it with a larger one (physical size) that has a 6 mm shaft. It also needs to be filed flat to be used with the original knob. Which I chose, to keep the original look. The value for the one I got was 25Kohm, but that is close enough to the 22Kohm that came with the controller.

Regards.

How did you manage to get the old blower of his axle ? was it mounted the same way as mine on the picture ?
It looks like my new motor has an axle thats a bit thinner than the original, it also has a flat side so i might not have to grind, question is, will the old blower fit on the new motor.......

The wheel on my new blower was pressed and glued on. I had to drill out the plastic around the shaft and break it free. A fair amount of rust on the tip of the shaft would also have prevented it from coming off.

From the picture of the shaft, your wheel looks like it is held on with a nut?

The original blower has a shaft with a 8mm diameter. You cannot put its blower wheel onto a shaft of smaller diameter than that. Except, of course, if you can find, or make, an adapter tube to make up the difference. That would be a challenge due to the flat part of the shaft, which an adapter tube also must have.


Title: Re: Watch out for that blower switch, it could fry your car.
Post by: richard on October 10, 2010, 11:01:55 pm
yes, my new blower has a nut, i think i can find a way to make the axle a bit thicker by sliding an metal tube over it.

How is the old blower mounted ? how did you remove it. It looked like it's also glued on or pressed on the axle. I am afraid i would break it if i put pressure in it by removing.

To remove the old blower wheel I held it between my legs and used a punch to beat out the shaft. You have to hit it firmly, depending on how rusty the shaft could be. But it is the only way I could find. You cannot pry it off in any way that I could think of, without risking breaking the old plastic.

A year ago I repaired the motor, but it did not last. there is a picture in that post showing how I removed the wheel:

The new blower is in place, and that's a big difference. The model i used was sold like a '95, i don't know if that is right, because this one has a nut and a axle with one flat site on it. The axle is a bit thinner than the original one. I crimped a hose around it. Placed some washers under  and on top of the blower wheel (do not have picture's of everything  >:( )
I think the wheel will stay in place. My new blower fitted in the original spot without grinding on the fenders.

Hi Richard.

It looks good. I am curious, because it looks like the motor is entirely outside the blower housing. Is the motor shorter than the original, or how did you get it to fit?

Also, the idea with the hose around the shaft is interesting, but is the wheel properly centered? no vibrations?


Title: Re: Watch out for that blower switch, it could fry your car.
Post by: richard on October 23, 2010, 10:37:14 am
the motor is outside the housing, the blower wheel is inside. Think it's the same as your modification as far as i can figure it out on the pictures.

(I am sorry that i do not have more detailed pictures of all situations, was to busy with the blower and did forget the photo shoot  >:( )

The tube around the axle was just a idea to fill the little gap. Future wil tell if this is stable enough to keep the blower wheel centered. Right now it's centered. The blower wheel has underneath and on top a washer and the nut presses them together. I think it has a good chance to stay in place.

Still have the original fan in the car, but it is end of life.
I feel it is dieing.
Some years ago a fellow member from the club put in a Golf 1 ventilator.
It seems a easy fix.
It will fit with very small adjustments and a simple job
Finding a Golf1 ventilator is another problem.
This is the 5th I found and the first one in good shape.
It runs like hell.

First I was pondering on what Hyundai Excel is. It is known as Hyundai Pony and Accent (depending on the year) in my country.
I think it is the easiest installation so far.
But the car is not so common...

I finished the work on my blower. Thanks for the tips in this topic  they were very useful.

After some research I found that the blower of Suzuki Swift (up to 2003) is very similar. As it is very common car in Hungary I bought a motor with the external resistors whiches are installed in the airflow in the Suzuki.

Now both are installed to the Murena's blower housing. I had to fix the original rotor to the shaft of the new motor and cut holes for air intake as others did.
After small modifications I could use the original wiring. As it uses external resistors there is no need of any contol module. It works perfectly, but the real test will come next summer... :)

I have to redo mine again, since the plastic broke and the motor fell and dragged the blower wheel inside the housing. A temporary fix with metal reinforcement should hold until I can come up with a better replacement.


Title: Re: Watch out for that blower switch, it could fry your car.
Post by: klumzer on September 19, 2012, 08:12:52 pm
Which part was broken?

The new motor is a bit heavier than the original, because it has a metal frame. It was quite difficult to cut the holes for air intake.
I hope the original plastic housing will bear the load... I used M4 rivnuts for fixing, it can be seen in the photos at the inner side.

It was precisely the original plastic housing that could not carry the load. Since the motor is on the bottom, when installed, the weight cracked the plastic from one of the screw mounts and the motor fell resulting in the blower wheel scraping on the housing and the motor drawing excessive current. The smell of burnt plastic and smoke from the switch, was a clear sign that something had gone wrong.  >:(
I made two "C" brackets of aluminum and placed them around the housing and a screw mount on opposite sides. That should hold it, but not pretty. I am still looking for a better replacement. Perhaps with a new housing.
I will post a photo when I get down to the car. It is at Philbert's place where I have been working on the brakes.

I need to look at the blower on my car as it it sounds like the bearing is failing, loud squealing at 1, 2 or 3.

But I don't know where to access the fan. How do I get to the fan housing?

You only have to remove a hatch under the bonnet. It is fixed by some screws. Then you can find the blower which is mounted by two bolts. Head of the bolts can be seen at the right side in front of the windscreen.
The  air outlet of the blower is connected to the car by a thin plastic gaiter. Be careful, do not damage it.

The hatch is just to the left and to the rear of the washer bottle in the first photo.  As originally built it would have been fixed by pop rivets, but some owners may have replaced them with screws.  Your bearings are probably just dry after years of disuse.  If you strip the motor down, clean it thoroughly and give the bushes a good soaking in oil that should do the trick.  You need to look after those motors, they seem to burn out very easily and it is quite hard to find replacements.

I am fitting my new blower fan whch arrived today.

Can someone tell me what the settings are on the fan knob ie: is 1 - Low, 2,  - medium, 3 - High? Or is 1 High?

I connected and tested the new motor and 1 seems to be high, which seems backwards to me. As my old one didnt work properly I have nothing to compare this to.

I have fitted a knew Fan switch too from CBS but it is identical to the old one. Is this a Matra thing or do I need to alter the connections?

Position 1 is the lowest and three the highest.  The motor should be connected to terminals 1, 3,4 & 5.  Terminal two is live on all three settings and is probably intended for an indicator lamp although this is not used on the Matra.

Thanks, got it. I had transposed the yellow and orange wires when I put in the new switch.
Runs like a charm now. The new motor is very quiet, smaller and lighter than the original and puts a lot of air through.

The switch lasted 30 years.
The problem occur when the blower motor is asking to much current for some time because of bad bearing.
The switch and wiring around it get overheated and finaly give up.
Since you already adressed the problem of the blower, yo should be fine with a new switch.

Very nice job.  :)
I have to redo mine again, since the plastic broke and the motor fell and dragged the blower wheel inside the housing. A temporary fix with metal reinforcement should hold until I can come up with a better replacement.

Hello,
