Replaced the battery and followed the proceedure to sync the back window, but it will not sync at all. The window drops when I open the tailgate and will not go up when closed, but it will go up if I use the key in the lock. Also the rear wiper has stopped working, and wondered if that has something to do with the problem or is the lock faulty.
If I try to open or close the window with the switch, it moves in either direction and I get the 3 bleeps. Any help appreciated
