Car is the 1979 300SD w116. Mine isn't working now. If I remove it and spray wd-40 in the small holes and put it back in it will work. I did that like 2 months ago, and it worked until recently it wouldn't work intermittently. I know this can be rebuilt because I have seen them for sale but is it something that I could do or is it too sophisticated? Also, how do I check the amplifier that is behind the glovebox?
Thanks
David
