1994 Suburban power window problem

[boattaillou]

I have a '94 Chevy Suburban with a driver's side power window problem. The window will work for 5-10 seconds upon initial startup but once I stop and try to restart, the window won't do anything. If I pull up on the window while pressing the window switch it will start working again whereas I can let go of the window and keep the button depressed until I reach the desired level I want the window to be. At times I get nothing up or down by pressing the switch leading me to believe it's the motor. It seems to have the most trouble going up rather than down. I am not sure what the problem is, ie. regulator, motor, electrical relay. Any help would be appreciated

if you use the window sw every time you run this vehicle on this vintage the switches are usually the problem.

with the NBS 2000 -2006 vehicles the window motor/reg are very much made to fail just after 3 yr/36,000mi..........

since it is failing constantly checking the voltage at regulator/motor input would confirm. could be the voltage drops at the sw because of wear.
