I had to manually hooked up a spare battery and wires to the rear window connections
to get window back up(went up with ample power,so i'm positive Window motor is good)

Any simply fixes? didn't find any corrosion on either front or rear
switch connections when popped out..tried giving both doors some whacks and driving over a rubble strip to see if connection(s) would return,but nothing.

 

Here's the wiring diagram (attached). With the diagram, you should be able to troubleshoot the switches to make sure that they are working properly as well as check for power & ground where appropriate for a given function.

 

I had the same problem that was caused by a bad switch. When I moved the switch to the other door, the problem followed it. Even the switch on the drivers door won't work.

 

I still haven't been able to get to this window issue,but i hit pay dirt yesterday after another visit to the afore mentioned 'rumble strip' hospital run on the side of the highway

..such a nice affordable medic that Mr.Rumble!
