Dennis, be nice, you forgot to tell the newbie "Welcome to the Club." You're forgiven.
Just follow Dennis's suggestion. But I'd also try and find some silicone spray or grease and lubed the weatherstripping in the window channels. It sounds like the motor is tripping its thermal breaker due to too much load.
I will say Dennis's idea with the hammer is a good one. I say this b/c when a car is under water, & you have power windows, one cannot get out UNTIL the interior has filled up with water and the pressure has equalized.
One of the most easiest tools is a spring-loaded center punch. There cheap, can be bought at Harbour Freight, Northern Handyman, etc. Stores well in glove box. Just place tool in corner of window by the outside mirror breathe in and hold,and push -- slazzam -- no window!! It just shattered. Swim to safety!!
I'll say it -- "Welcome to the Club"
