Power window - ZR-1 Net Registry Forums

secondchance · 01-30-2013

My driver side power window has been a bit slow starting from full down position to about 1/4 up then would move at normal speed. Interestingly, this reluctance gets worse with colder temperture. A couple of days ago when the weather got real cold, with the motor running (takes weak battery out of the equation), window took for ever to peak out from behind the door panel.
Does electric motor weaken with age? I always thought the electric motor either worked or quit. Also, could this be the counter-balance spring loosing its tension having gone through so many cycles and cold temp is aggrevating the loss of tension?
Either way, I think I will just replace the entire regulator assembly but sorta got curious.
