help cometh finally

Since there was a corner of the board that was slightly corroded, I was fairly sure the problem was there. We got lucky, it was the trace in the bottom corner of the board, on the side of the relay that controls the upward direction of the motor! The reason it wasn't working is that the trace on the board is really small, and it had corroded enough that it esentially had no conductivity anymore. All we had to do was solder a little "jumper" wire from the node where the trace began to the next component. Here is a picture: http://s15.photobucket.com/albums/a3...6-51-50_97.jpg

Are you good with electronics/have access to a multimeter? I am guessing that your problem is exactly the same as mine, since we both lost the same half of the window's functionality. It's worth a shot better than paying $165+ for a new window switch right?!

Let me know if you have more questions!

on receiving the above message the first evening that i got the chance I set about trying the fix. I removed and dismantled the window switch. I could see a slight flaw in the print but nothing that would make one suspicious of any shorts in the circuit especially as I do not yet posess a magnifing glass. I took out my multimeter and sure as hell the short shows up. As you can see from the photo below fitting of the red jumper wire has sorted the window switch. I now know that my problem never was the regulator or the motor.

Now on to the next problem. My passenger door is now stuck shut, unopenable from the outside and inside



Many thanks to aweber05

So had you since replaced the regulator or switch and resolved the problem? I am wondering if you replaced the regulator and if so, whether that fixed things or if you tried a new switch instead or this rewiring fix was your ultimate solution.

Ah, I missed your post #14 detailing the new regulator did not fix the problem.

Thanks for sharing another angle of our dreaded window problems.

I believe I have replaced 6, possibly 7, regulators.

i never would have found this solution myself. To look at the circuit board you would have no idea.
