Well - it has been a very long time since this original post, but turned it up in a forum search and I am having a similar issue with a likely faulty hazard switch (hazards not coming on for a '95 C280 W202 chassis, everything else on the dash and turn signals are fine). I understand that it's possible that the relay is in the switch itself?

I'm handy enough that I'd like to try to clean and/or replace the hazard switch myself, but after pulling a couple phillips screws from the dash below the factory stereo, I am at a total loss for how to remove the wood dash trim to access the switch. Any help or advice would be most appreciated and would also save me a trip (and thus some good $$) to the shop to replace a simple $15 part. Guidance anyone?

Thanks in advance.
