w202 c200
hey, I recently bought a 97 c200 elegance two months ago, and I noticed that I have the same issue, this is not always, but sometimes, mostly when its cold (as I live in norway this is common)...

But my buzz sound seems to come from inside the light cover in the roof just above the middle mirror... is that the same for you?

Sounds like two different issues. The latter is the sampler fan the air-co uses to monitor the interior.
