Hi Guys, I hope you can help me. I tracked this noise down the other day and it appears to be this small blower beside the glovebox liner and side vent (RHD car). I think it sucks air across the temp sensor in the dome light switch? The motor is stuffed and makes all sorts of great sounds. I pulled it apart and lubed everything up on the internals which worked great, twice! Does anyone know where i can pick a new or non-noisy second hand part up on-line at a sensible price? I have not asked Mercedes yet as I expect they would sting you for this, even with the motor having the "made in Taiwan" sticker on it...
