Just bought a 2006 GC and the power widows do not work. Knew it when we bought it but thought it would be a relatively simple repair. Fuse is good, tried swapping out the switch from our old wrecked one that works fine, but that didn’t solve the problem either. There is no hum, or sound at all when trying to lower or raise the window. Not sure where to go from here, there is a 25 amp circuit breaker that is located under the instrument panel near the steering column but I read that these were self correcting and that another problem somewhere else would cause this to blow and would fix itself once the underlying problem was repaired. Trying not to have to bring it to the dealership. Any suggestions?

 

I would try removing one of the door panels and check the window motor for power and ground or if the motor is unplugged.
