My drivers side power window has been playing up for ages and I have been trying to find the root of the problem. It would work most times, then all of a sudden just stop working. If I bashed the door handle and switch surround a couple of times it would sometimes start working again, but also sometimes not. Then it would work again for no apparent reason.
First I thought it was the switch mechanism, so I pulled it apart a couple of times and checked everything, and re-soldered anything that looked dodgy but it never fixed the problem.
I found the culprit to be the relay/switch (mentioned in the thread above)for the auto power window. If I moved the plug connected to the relay around a bit it would start working again. Interestingly though, there was always a ticking coming from the box when you used the window switch, whether it was working or not.
I didn't really have time to look at it properly when I first discovered it, so I cable tied the plug in a position where there was obviously a decent enough contact to get the windows working, and left it at that.
That fix was all working fine for a few months, but the other day I got stuck with the window down and it wasn't going up for love or money, so I was forced to take action.
I have taken some pics that may help others (the quality is crap)...this was the procedure:
Remove door trim -
- FIRST! remove the plastic cap in the armrest well and undo the screw located underneath, that is if it hasn't already been destroyed by some other monkey, in which case there will be a gaping hole where the plastic mount point used to be, so skip this step. Mine came broken
- Then, remove the plastic surround containing the window controls - there is a plastic clip underneath the centre of the surround holding it down so just lift from the outer edges in the middle until it pops out.
- Next, remove the surround from the door lever/lock mechanism as outlined in the pic
- Then, remove the three screws at the bottom of the trim as indicated in the pic and pop the push clips out on either side of the door. Then remove the door trim by lifting out and up from the bottom.
Locate and remove relay -
- Locate the relay to the right of the handle. Remove the plug and two screws holding it in place
Dis-assemble and repair relay -
- Lever the end off the relay with a small screwdriver or other weapon of choice. Pic shows lever points note the care and patience taken
- The relay PCB is just sitting in there on some plastic runners and slides out easily. Remove and check all the soldier joints on the back for anything suspect looking. Mine was pretty obvoius as shown in the pic below
- Re-solder anything that looks dodgy. BEFORE you put it all back together, plug it back in to the loom, connect your window switches and make sure it works. If so, re-assemble the relay and put everything back on in reverse. If it's still not working set the car on fire and call the insurance Co.
