THe cigar lighter in my 1987 420SL is non functioning, nor is any light that may be there to illuminate the ashtray. The fuse is OK. The only clue could be that when I pull the ashtray to open it, the whole ashtray comes out, i.e. the metal 'spring' is not retaining it.
Is there a lead that should plug into the ashtray to pwer it?
