All power windows inoperable 1987 240

Hello everyone!

None of the power windows in my 240 seem to work. I didn't touch anything to do with the windows, they worked one day and didn't work the next. Front or rear, left or right. It doesn't matter what switch I use either. The fuse was good but I also connected with an alligator clip from one side to the other on the fuse panel and still nothing. My guess is I've got problems in a ground or somehow with the wiring.

I suspect you have a wiring fault somewhere in common to all windows. Do all the door window switches fail to operate windows? Do you have an electrical schematic?

Yes all four of the door window switches don't do anything now. I have a switch for the driver's door that I might be able to swap in, but I figure that's not actually the issue anyway. I haven't gotten a chance to find a schematic yet.

So I had a second switch, that I swapped in for the driver's one, and still nothing. I guess its a problem behind the fuse panel. Trying to figure it out because its getting warmer and windows will be pretty much the minimum sooner than I think probably.
