560 SL Heater/AC Fan
 

I believe that I have a handle on the location of this fan and have been told that I may not need to replace the fan just because it is noisy.

The noise started about a month ago and comes and goes.

Is there a part that might cause the racket, or am I looking at a new fan?

What kind of DIY project is this?

Thanks for the help!

The blower is under a plastic plate secured with screws on the top of the firewall. It is a fairly easy replacement. Be sure to put some penetrating oil on the four screws holding the blower in as they rust and can break easily.

You might have a broken "cage" causing the noise rather than the motor.

Rebuilt units are readily available from Partshop and other suppliers.
