Is there a blower motor relay I should check?
20

Asked by imyt19 May 29, 2014 at 09:33 PM about the 2002 Mercedes-Benz SLK 320

Question type: Maintenance & Repair

My a/c was working intermittently, so I replaced cabin air filter and removed debris,
leaves from blower motor...no change. I then got a replacement blower motor resistor
and a/c worked on all settings, but when I remove key from ignition the fan keeps
blowing. I was sent another resistor, same results. Is there a relay somewhere that might
be stuck on causing this, or are both resistors likely bad?

Thanks. Any idea where the relay might be located? I'm guessing it is in the vicinity of the blower motor?

I forgot to mention, when I put the old resistor back in the a/c is still intermittent, but it does turn off as expected when I remove key from ignition.

imyt19, did you resolve this issue? Was it a relay? I have similar issue with C350 2006. Replaced motor and resistor and the fan runs at high. No speed control. Thanks,
