Power window acting up - depressed i can't fix
 

Hi

Originally, the motor was failing on hot summer days, a common problem with 2003 mustangs. I
removed the motor and regulator assembly. Applied grease to the rubber stoppers inside the motor.

I am able to install the assembly no problem, however.. without installing the motor I try moving
the window up and down and the white guide clips are hitting on the window guide. The clips feel
firm and do not budge nor do they look destroyed.

When I remove the regulator assembly, i can tilt the window as needed and it does not hit. With the
regulator installed, it always hits no matter how i position the window.

Please help :(
