Does anybody have any idea why would this be happening ??

MY rear driver side window will only go down but wont come back up; tried both switches front and back and both will only allow the window to roll down?

(please help any advice would be great) NOBODY HERE WOULD LIKE TO SEE A G35 WITH A PLASTIC GARBAGE BAG COVERING THE WINDOW!!!!

 

Sounds like your window motor needs to be replace. I have an 04 coupe that was did the same thing on the drivers window. I thought it was the switch because it would roll down and not back up so I bought the switch assembly with no luck
