So I'm doing a sound install, and I'm in the process of putting my interior back together. I did the driver's side, reset the windows no problem. With the passenger side, when I auto-roll up (door open or closed) the window drops back down about halfway. The window also doesn't drop at all when I open it. I've tried resetting it dozens of times, no luck. Any ideas?

 

How many miles on the car?

 

53k. its an 04. I didn't think it would be the motor as it goes up and down no problem, no hesitation. but the more I look around, the more I see this is a precursor to a blown motor.
