my passenger side window is slow AGAIN... this is the third one that i've done for that side all covered by warranty. i'll replace the motor and it'll work but not very fast, then gradually burn out till its time to get a new one.

how do i check the resistance on the switches? could they be making it run slow / like crap?

 

Yes it can make your windows run slow. All you need is a meter and a manual. A Haynes would even be enough.

 

Here is a schematic. Just plug your meter into the appropriate location and read ohms when you operate the switch.

Notice that some connections are fed to the RH switch from the LH one, so you might want to check both switches and maybe wiring.

 

Another problem is that people aren't greasing the regulator and rollers when they change the motor. Also check all the window positioning adjusters, they can be putting undo force on the window.

 

this schematic is difficult to understand. does each power window motor ground out at the power window motor or does it go to a centralized place to ground out?

 

The ground comes from another location and is fed through the switch on the driver's side. Battery and ground are reversed by the switch to the brn and drk blu at the motor to make them run backwards to roll the window up. The switches in the schematic make it a little hard to read.
