Gotta love the electricals in these things...

ANyways, both my power windows just suddenly conked out at the same time. What contacts should i be looking at? I know it's not the motors, one of them is new. And it doesn't make sense that it's the switches... both at the same time? Any help would be appreciated.

Tx,

probably the switches , mine went and once switches replaced worked fine. try cleaning them , if this doesnt work, i picked up 4 used switches on ebay for about $20 three worked so I had a spare

 

I figured out the original problem. Fuse. Stupid me.

Anyways, the problem has a part 2 to it. I've replaced the fuse THREE times in the last week 'cause it keeps blowing. What the heck? I've had the car since january and replaced one window motor in February... and i haven't had any problem like this till now. Any ideas?

Most likely one of the windows is binding and working the motor too hard. If you leave it cranking it finally blows the fuse. Probably the window you replaced the motor on. So, make sure things are aligned, lube the regulator joints and wheels, spray silicone in the window tracks, etc.

 

check the wiring where it goes through the gators between the door and pillar, a stalled motor will draw 10 amps, it is current limited by inductors in series with the brush holders, tired motors draw less due to commutator wear, check the wiring to the motor you installed hasn't caught around the door stay inside the door also as this often happens after the door has been apart and the wires are not tied in place.

 

And a further note on the wires in the door-hinge pass-thru:

The conductors can break from fatigue without breaking the insulation, so the break is not visible and can only be found with some form of continuity test. Been there, done that. AARRRGGG!!!!

Jim, musta been cheap East German wire... Trabant leftovers, maybe?
