Hello, I have a clk320 1999 and the a/c fan won't stop blowing even when turning the car off and removing ignition key. I disconnected the baterry for 2 hours and put it back on but the problem stayed.

Any suggestions? I appreciate it in advance.

 

blower regulator, right on the actual blower motor or beside it. under the passenger dash panel. at least the ones ive seen..that was the fix. regulator is about 150$ at a dealer, probably more actually.
