Today both of my power windows stopped working and they won't roll down.

I followed the instructions in another thread:

Right (passenger's) switch:
There should be power at pin A (brown wire).
Press the switch for down, there should also be power at pin C (the other brown wire).
Press the switch for up, there should be power at pin D (dark blue wire).
(You'll need a helper for the next two) Press passenger window down switch on the driver's door, you should get power on the passenger's switch at pin E (tan wire) as well as pin C (brown wire).
Press passenger window up switch on the driver's door, you should get power on the passenger's switch at pin B (light blue wire) as well as pin D (dark blue wire).

Left (driver's) switch:
There should be power at pin F (brown wire).
Press the left switch for down, you should get power at pin E (gray).
Press the left switch for up, you should get power at pin D (dark blue).
There is no need to test the right switch if you got the expected results while testing the passenger's switch because it must be working. If you did not get power at the light blue or tan wires on the other side then test at this switch while pressing up and down respectively. If it works here but not at the other side then there's a break in the wiring between the two switches.

And both switches show all of the proper voltages.

Many years ago I did a few mods around the windows - a little hazy but it was some kind of direct wire to the passenger side so it would get more voltage and roll down faster, and I also put in an aftermarket module for express down on the pass window, as well as rolling down on 3 unlock taps, but I've had that bypasses for a while now.

Anything thoughts what it might be? Since it has all the proper voltages at the switches it seems to rule out the mods, and if it was just a bad motor or lose to one, the other should still work?

 

You'd have to reverse engineer what you've done in the aftermarket. The switch voltages are just inputs to the relays and modules for express down and that other kit you installed. The actual power to the motors would be supplied through other channels. (Maybe separate fused circuits.)

 

Yeah, was hoping something obvious I missed since seemed to have both at both switches. It's been about 10 years since I'd done the mods, I took a look at them this afternoon and just playing around with them started working again, I guess maybe something was loose
