Post Problem with window SC300!

Okay let me start off, I did search but came up with nothing a few leads but not solid. This all started about a week ago I just replaced my drivers side regulator due to the wire snapping. Then noticed that the passenger side was starting to get slow when being rolled up till one day I rolled her half way and she never went back up again. I thought the motor was going so I went ahead and replaced the whole regulator.

Well while doing so today I installed the new regulator and actually tested the motor to see if it was working. I was surprised that it wasn't working either. I remembered I had an extra motor laying around, plugged that in and sure enough that wasn't working either. I checked all the wires that were visible everything was good. Using the drivers side switch doesn't work neither does the passenger side. I can rule out the switches, I'm not completely sure if we have different fuses from drivers and passenger windows? Can someone please chime in I'd greatly appreciate it.

Before you do a lot of wiring diagnostics are you sure the second motor was still good? I bought an alternator from napa once and it didn't work so I thought I had another issue until a buddy of mine told me (after about 20 hours) to have them test it and sure enough it was dead.

Good luck

Hopefully you state out the obvious already, is the window lock pushed?

Usually the regulator dies out before the motor. I had 2 broken regulators and both of the motors still working. Make sure you lube your window sill so there isn't friction when the window slides up.
