1989 Mercedes Benz 300e 6 cyl Two Wheel Drive Automatic 183, 00 miles
None of my buttons to turn on the AC, Heater, and anything else near the radio are working. The buttons towards the center console to adjust the side mirros and to put the front windows down, they do work. The buttons for the rear windows do not. I don't know if it can be a fuse or where else to check? Thanks for any help.
