Tailgate cannot be opened.

[matra530]

Hello, my Murena ist showing his femine side and being bitchy. The Bowden cable for the tailgate has insufficient tension on the right-hand lock. As a result, I am unable to open the tailgate.
How can I raise the tension slightly from the outside to access the adjustment? Remove the belt, remove the B-pillar trim, or is there a better approach?

Might be able to open it if someone presses down on the glass a bit as you pull the lever on the b pillar.

We tried that. It works on the left, but unfortunately not on the right. I'll probably have to remove the lever in the B-pillar. Hopefully, it's only held in place by the one visible screw in the base plate.

Looking forward to hearing if it is.

Interesting thing, i call mine the same lately.
Hi, my name is Hobel and i life in northern Germany.
I have 1 and a 1/2 Murenas myself and i`ve been reading this forum for a while.
I`ve had the same problem. Everything worked fine until i lubricated it.
There are, maybe, two ways to open the trunk. Both worked on mine.
Should i post that here to the public ? Or should i get a personal mail to answer?
I don`t want to be resposible if they break into our Murenas.
What do the senior members think ?

I had this problem several times the last few years.
What I found out that the cable stretches so the right lock start  to have problems first.
To fix the problem pertinent I made a thicker steel rod from one lock to to the other, the cable from the B-pillar stayed the same but relaced it for new from a bicycle.
This made opening more smooth.
Les effort is needed to pull open.

There are several things here and it could also depend on the particular Murena you have, because if you have a 1983 Murena, the rear of the lamps are completely sealed off from the boot, by metal covers welded to the shell.  The earlier cars have fibre covers and the rear of the lamps can be accessed from the boot.  What has this to do with the tail glass locks?  I don't want to say this in an open forum so please email me on my domain name, (not here) and I can explain further.

The problem you have is that once the left lock is pulled to its furthest point when you pull the cable normally, if the right lock has not opened, no amount of extra pulling is going to release it as the cable is now restricted by the left lock at its maximum.  The problem as you have realised is that the cable between the locks is not taut enough.

Once you get the lock open so you can rectify the situation, one solution for future reliability is to replace the cable between the locks with a solid piece of piano wire similar to the cables used for the heater controls (and similar to what Herman advises).  Once the adjustment of that solid wire makes the two locks work together, then it only requires the lock on the left to have sufficient pull to release it, and the right lock will always release too.

Yes,
i`m sure Roy knows the other way, for the younger Murenas, as well. It goes right through the lock. So i won`t explain it further, here in public, either.
I see it is possible to mail personally...

[Grapes]

There's probably very few murena things Roy does not know 😅

[matra530]

Tried do fix it, now it works on my right side, but not on the driver side.... Mad day.
