So my car was involved in a hit and run unfortunately one of the doors had to be replaced. However after the door was replaced the automatic function stopped working (I never really open my rear windows so it took me a month to find out) I tried to reset the window by holding up the button for 5 seconds for it still doesn't work. Any ideas? Maybe it's missing a piece or something?

 

You have to hold it down for 5 seconds too

 

In my experience I didn't have to. I just recently discovered this "reset" process for the windows which was great because the express-up had stopped working on all four. I rolled all the way down (not using express) then rolled all the way up and held for five seconds. It fixed all four of my windows.

 

Window Reset Procedure:

Roll window all the way down "manually" roll window all the way up "manually" and hold for 10 sec without letting go run fluid motion then release should be all set

 

I've tried it too but it just doesn't work.

 

 

hope this helps
