Hello

My problem is that my a/c is still on even after i turn the car off. The only thing that works is un pluging the battery. I pulled the fuse and it was still on.
Please help!!!!!!!!!!! It is a Pontiac Grand Prix. year 2006. 3.8l engine.

Re: a/c will not turn off Sign In

Are you referring to the blower portion of it?
Is it an Auto Temp Control system?

Yes sir. I am referring to the blower portion.
It is not an auto temp control system. Yesterday i used my defroster to clear my windshield during a rain storm, but once I got home my a/c would not turn off even though the engine is turned off.

Then what your likely problem is is a bad blower speed control module. It's located under the dash on the passenger side, right next to the blower motor.
