Power window trouble
HI, advice needed , When I try to run window up or down, It will move only about one or two Inches and then it stops. I can help it some by pulling or pushing with my other hand.
After waiting a few minuets it will move another inch or so. I have to go through this ever time I put the window up or down.
What think ye? should I suspect the motor or the switch or what else? This is a 1994 S15 Jimmy .
Thanks

If I am correct, that has a regulator lift arm that is supposed to be under pressure from the counterbalancce spring. Maybe your spring is not balancing and allowing the motor to glide. I would take the panels off and take a look.
The motor may be weak, but if the mechanism is not in top working order, it may be binding and keeping it from working.

Suggested Repair

Remove the door panel and inspect the window regulator lift arm and counterbalance spring for binding or loss of spring tension. Also check whether the window motor is weak, since a binding regulator can prevent it from operating properly.

Conversation Summary

A 1994 GMC S15 Jimmy owner reported that a power window moves only one or two inches before stopping and can be helped by hand. After waiting, it moves another short distance. The expert suggested inspecting the regulator lift arm and counterbalance spring for binding or inadequate spring pressure, while also considering a weak motor.
