Does This Sound Like A Wiring Issue?

[GLPoomobile 958]

At the weekend I fitted a replacement passenger door loom that I purchased from a fellow member, so that I could fit my electric window mechanism.

 

I didn't think to inspect the loom before installation but nothing grabbed my attention in terms of split wires or dodgy insulation etc.

 

Since fitting it I've had a couple of sporadic problems. Firstly, the window motor does not always work (was fine when it was in my old car) and it'll come back on if I bang the door skin or jiggle the switch (still hanging loose in the door as the door card is off). Secondly, on a couple of occasions the CL has malfunctioned, so when I lock the car it pops open immediately. The first time that happened it wouldn't stop doing it until I opened the passenger door and pulled the knob up and pushed it down a couple of times, but now I'm thinking that it may simply have been the action of opening the door which would disturb the loom slightly that may have rectified the fault.

 

I'm thinking there may be a dodgy wire in the loom, maybe earthing or something, that is causing this.

 

Does that sound logical?

Id inspect the plugs on both of them.

 

My passenger window switch works when it like aswell!

Yep sounds entirely plausible.

 

I have a similar issue - but even weirder than yours. When I fitted a new passenger door I swapped over the whole loom, central locking motor and window motor from the other door. Everything worked perfectly on the previous door. When I swapped it though, the passenger window button would only make the window go up, but not down. It would however go up and down using the drivers window switch..tried swapping switches over but to no avail. It did keep blowing a fuse when we were in Germany though (meaning that the window couldnt be closed). In the end we had to stick a much higher rate fuse in to get it to go back up. There is obviously not a problem with the motor or either of the switches. At some point Ill have to get round to rewiring the whole loom in the door. I guess it a safety feature if I have a passenger in the car, I know that they wont have left the window open!

Job 98 on my list of things to do in the next two weeks - remove sodding loom again and inspect it all.

 

Bastard.

I'm with Alastairh on this, check the plug on the a pillar first. As they can be a B. to remove they can get pulled out sideways when unplugging, opening the female ends.No female wants too much slack- so they refuse to do what you ask of them......................

Pillar? Are you thinking of the Ph2 looms that have they annoying connection at the door?

 

This is the earlier loom that goes straight through the rubber conduit, up the side, and to the connection under the dash.

Check the switches for dust build up.

 

Whenever mine have gone like this its always been fixed by popping the switch out & cleaning the built up dust etc out.

 

Works perfectly afterwards.

Quick update....

 

 

I've found the problem with the leccy window. Dodgy connection at the motor. If I move the wires about whilst winding the window then there is one point where the connection will break. The wires themselves are fine and the spades are OK and in place etc.

 

On the passenger side motor the connector is at the top facing upwards with the wire coming up from below, so they end up doing a 180 degree bend back on themselves and a lot of stress gets put on them. So I've cable tied that part of the loom to the bracket that holds the front window guide to the inner door skin and made sure there is plenty of slack up to the motor, so hopefully it should be OK.

 

As for the central locking, well I've not had any more problems but I suspect a dodgy drivers side motor. I'll probably just replace it with a spare anyway.

Cool, I'm hoping this is the same with mine...it likes going down but not really up.

That could be either a poor motor or a nearly siezed window winder mechanism. The motors will tend to draw more current if you put too much force on them, e.g. the window winder is nearly siezed or if the motor is about buggered.
