I have a 2005 Tahoe that has a malfunctioning right rear(door)window. There has never been a problem when it was working, with a tired/slow motor. It either worked or it didn't.
When I unlock the switch on the driver's door to allow the rear windows to operate, the left rear window works fine, but the right rear window doesn't try to move, except the lights dim slightly. Any ideas? I don't think the right rear window has its own breaker circuit.

If the light dims, the fuse is not blown, Likely the motor is bad, if your not mechanically inclined, you may not want to change. Or go as fas as you are alble to, and reassemble.
