Always willing to get my hands dirty, I was rewiring the right taillamp cluster on my '86 300E. Stupidly, I left the key in the ignition, made a little spark and blew the fuse (#3). I replaced the fuse - but still no brake lights or dash control elements! However, the combination relay (201 821 00 47) has started buzzing whenever the car is on. Replacing the relay with one from my 300TE doesn't help - it buzzes too, and the 300E relay works fine in the 300TE. I can't go very long without brake lights so I'd really appreciate any feedback.

Thanks, as always, for everyone that makes this such a great site.
