So I was driving and I started putting my window up and as soon as it reached the top I heard a pop. Kinda sounded like the window itself hitting something. After that, the window fell down. I try to turn it up but it’s not moving. I hear the motor running. And I can’t move the window up with my hands. Can someone help me potentially diagnose what part messed up?

 

Yep. Happened to my regulator on the passenger-side the same way. Went to put the window up, heard a pop and it just lowered all the way and couldn't put it back up. Replaced it with a used one. For some reason the passenger-side one tends to go more often.

 

my regulator repair kit arrived with 2 cables, amongst other parts. the longer cable measured 32 1/2" the sleeve on the longer cable measured 11"
the shorter cable measured 32 1/8" and the sleeve measured 6 7/8" Hope this helps you DIYers
