When I drove the Espace home from the mechanic after the engine job, I found that the passenger side window couldn't close! I drove home with it open all the way
At home, I tried to find out what was wrong, but ended up powering the window motor directly on the switch connector to close the window. At least, I knew that the motor was all right...
Initially, I thought the passenger side switch was to blame, and took it apart and bent the terminals so it could act as a bypass connector, still allowing the window to be operated from the driver's side. But when that didn't help, I checked the other switch, and found out that it was probably the defective part! So two new switches ordered from my regular Renault parts source.
They arrived yesterday, and I fitted them last evening. Alas, the problem was still the same: The window would wind down - NOT up.
It turned out the drivers side door wiring connector had a defective terminal:
And more, the insulation was also broken on two wires:
Apparantly, the wires and the connector pin have been damaged by opening and closing of the door, and since the wires run loose inside the rubber hose, they have been able to move freely back and forth, rubbin the insulation apart, and eventually breaking the connector pin.
This is where it may become relevant to others here on the forum, my car can't be the only one suffering from this problem.
Well... nails are handy for all sorts of jobs, aren't they? (look below the grey wire)
I simply pushed a shortened nail into the connector, forming contact between the broken off wire and the remaining end of the connector pin. After taking the above photo, I wrapped it all well in insulation tape to keep the nail in and the wires from moving too much. I hope it will stay in now.
I'm going to look for a new (used?) wiring loom for the door now, unless I can find new connector pins for this particular connector, but Renault usually prefers to sell completely looms, so I'm not optimistic. But the window is working again now!
