Help Electric Windows Aargh

[Guest Demonjams]

As quite a few of you know I'm restoring my cab, but I'm having a right pig with the two front electric windows they worked perfect before I stripped the car down for the respray, now I'm trying to drop all the Windows back in both Window motors aren't working!!!! Now the first thing I've checked is the fuse and the fuse is ok, so then i got the circuit tester out to see if there was power and I've got power all the way down thru the switch and to the motor. So I took the motor off the window regulator and shorted it out of the battery just to see if the motor was knackered, and nothin happened! So the motors knackered yes??

But for both to be gone? After they worked perfect before!! Is that just a massive coincedence or what?

Or am I missing something? Any advice or comments would be appreciated

How did you wire thd motor to the battery?

The earth for the motor through its body which goes on the negative of the battery. Put the positive to one of the terminals to turn one way. Swap the live to the other terminal and it should run backwards.

From my experience it is quite common for paint jobs to unintentionally create bad earths due to the paint and would look at this. Maybe the doors no longer have a good earth?

A simple test would be, with the motor installed in the door, to run a thick wire from the motor body to the striker on the pillar to give it a good earth and try it again.

If it works then it is an earth fault.

To fix it you may have to remove the doors again and take the paint of so that the hinges make good electrical contact with the body. Remember the motors will take about 10 amps to work.

Good luck.
