Update, so i learned that these pieces of tape are original. so back to square one....

I am starting to go into a new direction with this: ever since i acquired the car two months ago, the rear windows have not been working.they are close all the way up, but the motors don't work....maybe they are not seated up all the way? i will post pictures of my window seals so that you guys can see those too........just in case i am missing something....


this is driving me crazy !!!

EDIT: Never mind: I taped the rear windows with electric tape to eliminate any leaks, test drove..........no change......

I am so frustrated now, i think i need to look outside the cabin for noise sources.....

any ideas? i am out of them
