Ok. On the driver's side door, there are two power window switches, when pulled all the way back, they go into an automatic mode and scroll the window all the way up.

This was the case.

Now I found that only the drivers side will automatically go all the way up, and the passengers wont.

I didnt do anything to it, Whats going on??

 

you can reset it... refer to your manual
