I recently replaced my original battery for my 99 E320 at a local garage. Now my moon roof will open but not close. I tried the remote key to open & close as well but that too will only open the roof. I don't know if there is a relationship to the roof not closing and swapping out the battery. It worked great before but now only opens. HELP!

 

Push the sunroof switch straight up and see if it moves shut. If it does let it travel fully closed and tilt up all the way. When it hits the top, hold the switch up for two full seconds or untill you hear the motor click off and this should resync the system.

 

Thanks a lot. I hope it works. I'll let you know.
