Hi everyone! I'm brand spankin' new to this forum. I'm a 2003 CLK 500 owner and for a while now there has been a squeaking noise coming out of the right side of my dashboard when I accelerate from stop - it sounds like it's coming from behind the glove box. Sometimes it's low, sometimes it's loud, but it's always there. Does anyone have any idea what this annoyance could be?

 

Like birds chirping? It's probably the cabin ventilation fan. The bearings and mounts get a little weak and do this. You can try cleaning the squirrel cage fan and lubricating by accessing it behind the air filter, above the vehicle battery.
