I'm looking to see if anyone else has experience with a similar problem. I have a 2000 Chevy Astro with a power window that only raise one or two inches at a time. After a bit of motion, I need to let the window 'rest' for about 1 minute, then it will again raise one or two inches. This problem appears to get worse in hot weather, but has been increasing (I mean the distance travelled on each attempt is decreasing) of the course of the past several years. Should I simply have a new motor handy when I tear into the door, or could there be some other cause to these symptoms?
Thanks
