Is there a blower motor relay I should check?
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?
There is a relay for your ac blower,could be bad,making it not turn off,points may be stuck.
Thanks. Any idea where the relay might be located? I'm guessing it is in the vicinity of the blower motor?
Should be under hood in fuse panel
If you dont find it there could be in trunk
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,
