Power Window Help!!!

My power window motor (passenger side) just died on me. What’s even worse is that it is wide open!!

I checked all the wires, the fuses, and the switches are all good. then I did the PW motor test described in the helms and it didn’t work so i know for sure it’s a busted motor.

Does anybody know how to get the window up to the closed position without a working motor??? I tried playing with the regulator arms and they are freakin solid. It won’t even budge a little.

Does anydoby know how much it wouold cost me to get this fixed??? please help, it’s getting cold here in TX.

One more thing, do i really need the plastic thing glued to the inside of the door??? what is it’s purpose?? o want to rip iot off and leave it off.
