Hello everyone: I am looking for an initial answer for what is the cause of the heating/cooling system failure on my 2002 ML320. I get no air of any kind. No fans, defrost or even any sound. Nothing at all. Thank you!

 

First check fuse #16 in the underhood fuse relay box. Then check fuse #5 in the right side kick panel fuse box.

 

Update: I found out there are no error codes curtly on my 2002 ml320. Still no heat or AC . Something else is causing no 12v to climate control mod.
I have fan control, but it's not climate controlled .
And I have checked all fuses, all good..
Help..
