Question type: Maintenance & Repair

both passenger & driver's side power windows only go up about a 1/3 of the way. After a few minutes they go up further & a few minutes alter up all the way. Any clues?

Most power window systems are protected by a circuit breaker. When an overload occurs the circuit breaker trips cutting off power. After a few minutes the circuit breaker resets automatically. Try removing your door panels and lubercating the window mechanisms with white lithium grease. The window motors might be working too hard because the window mechanisms are dry and need lubing.

I was going to suggest the same thing as Js08016 did. It sounds like the works are gummed up, depending where you live, it is a common thing. Salt air environment, hot sandy areas, humid dusty or crop dust environment or just cold/hot/ weather. Check for clearances and adjustments also. The motors may need looking at since they have been working on a strain, and may be near burnt out.
