Hey guys I just picked up a 96 S500 for a deal. Now I have to fix a few things the suspension in the back is super bouncy getting new accumulators, needs new mirrors, the engine is tapping found out that it is the camshaft oiler tubes, but I'm having a issue with the a/c, now it's cold no doubt but there is a wierd smell to it and it happens when something turns on not sure what it is but it is between the overhead light right in front of the sunroof controll there is a little hole and it sounds like a little fan not sure what it is but it's driving me crazy, any thoughts and what that is and how to replace it.
