Both of my power windows will not go down. I tried the passenger side switch and both of the drivers side switches with no luck, I can't imagine that all 3 switches went bad at the same time. I checked the #3 20 amp fuse for the power windows visually and for continuity, it is good. Is there a relay and/or module for the power windows somewhere?

Thanks for any help! :shrug:

Give us a hint here of what you have. I assume it is a 451, and maybe a little back history.. I would guess you checked battery and for power at the fuse??

Sorry! 2008 451 Passion. I only checked the fuse for continuity. The battery tested bad a few days ago and was replaced.

My first smart. 2008 Pure, had a bad solder joint in the SAM and caught on fire with 17K miles on it. Only had it a few months. Hopefully that isn't your problem. Could be a bad connection at the fuse, or maybe wires going to the drivers door. Most cars, if the drivers side switches go out, the others wont work either.

Visually the old fuse looks fine, continuity checked good on 2 different voltmeters, and power was present. When bypassing the fuse the windows worked fine. I replaced the fuse and they work again...

It does not matter how the fuse looks. It needs to have power on both sides for the windows to work. Use a volt meter while pressing the window switch or use a 12 volt test light. If the fuse tests good test for power and ground at the window controller under the dash on pins 1 RED/WHT for power and pin 4 BRN for ground. Depends on what year Studebaker you are working on.
