Another fan on full power and running on when switched off. Hi all I’ve got a cls 350 2012 with a fan problem, I’ve read lots of threads on here relating to this problem but still not found what will solve my problem.
Had the system checked, this is the finding, M4/7 air con & integrated control fan has an open circuit.
Question is what is needed to fix the problem, any help much appreciated
Thanks Colin
 
Possible broken wire, usually down near fan multi plug. Or it’ll be the fan module itself, think you only get that with a fan assembly
 
Hi,

Did you get to the bottom of this issue my e350 has started doing the same, Fan turns its self on long after the car is switched of and locked and keeps draining the battery.

Starting to lose my patients with it. STAAR doesn't seem to pick it up either.

Cheers
