GMC Safari electric windows
Question:
This just started recently on a 1997 Safari. Occasionally, the drivers window will no go back up all at once. It will go up an inch or two and then you have to wait for something to reset. I did notice that if I turn off the key and turn it back on, the window will move up some more. Again, this is not an all-the-time occurrence. Most of the time, the window works normally. Any ideas?

David, I just purchased a 97 Astro and have a similar problem. In my case, shifting to park seems to fix the problem. BTW, what MPG in town and on the road do you get? Doug
Response:
It’s a mix, but I think I average about 15 mpg. Haven’t checked it in awhile. – Hide quoted text — Show quoted text – > David, > I just purchased a 97 Astro and have a similar problem.

I had a similar problem with an 88 Pontiac 6000. It turned out to be the nylon sliders that slide back and forth in the channel at the bottom of the door. It had worn out and would cause the window to be slightly cocked. This would cause greater drag and cause the breaker to to trip. After a few seconds the breaker would reset and the window would go up a bit more. After replacing the slider, cleaning the track and relubricating it with white lithium grease, the problem never returned. Was about the only thing that worked right on the car when I got rid of it last year. Tom Miller – Hide quoted text — Show quoted text – > This just started recently on a 1997 Safari.

Response:
There is a circuit breaker built into the switch, I think as a safety feature to prevent someones head or other body part being crushed if stuck in the window as it goes up…. :) This is what is "tripping" and resetting after a few minutes. Why?? 1. Could be a bad motor drawing excess amps and causing the breaker to trip. 2. Could be a weak breaker, tripping before it should, as was my case. 3. Could be bad slides causeing the motor to work extra hard as in 1. above. Don – Hide quoted text — Show quoted text – > This just started recently on a 1997 Safari.

Thanks for the info. Naturally, the warranty has expired. I will check those areas.
