Power window motor problem
I have a 95 Ford Bronco that the driver side power window motor keeps burning out. The passenger power window and the tailgate power window both work fine. When I replace the driver side power window motor it lasts about 1 month. It never blows the fuse. Any ideas what keeps burning the motor out. Thank you.

I can't think of too much off the top of my head. Electronic issues like this can be a nightmare to deal with sometimes.
You've probably checked, but I'd make sure the plug on the wiring harness side for the drivers side motor is in good shape. It may be possible that the plug is kinda burnt up which could be giving the motor a bad connection. I would think that if there was a power surge or something, the fuse would blow to protect the motor. I'd also try and take a look at the window switch for the driver side motor. I may be wrong on this, but I believe the power runs through the switch for the motor, so if the switch is getting worn out, it could make the motor seem worn out as well. I know the power runs through the switches for the tailgate window. When I rerouted the power to run directly to the motor, it made my tailgate window move incredibly fast. I was about ready to replace the motor (being that it is the original 96 window motor), but it works excellent now that I wired it up differently.

Aside from garbage motors, (you aren't actually buying reman ones are you??) I would suspect a ground. Yes, poor voltage in (+) could cause it, but more than likely it would be a ground problem. Use a dvom and check the ground on it to make sure you don't have excessive ohms. You can go to the other door for a good base reference.
