210 chassis rearview remote receiver busted
I have a problem with my 1997 E420 that I discovered soon after purchasing it. The central receiver on the rearview mirror for the remote locks/alarm does not work. I have to be very near the drivers door or the trunk to lock/unlock the doors. The red/green lights in the rearview mirror that signal when the doors are locked/unlocked also do not work.
The red/green lights on the driver's door and trunk work fine. Where should I start on this? I have never been great with electrical.
