If you have 1990 and beyond try the following:

-see if your cabin sensor is working( it is the little 1inch square black grille)

-see if your ACC system has generated any faults, this is done by holding down the "auto" and the vent button at the same time for 30 secs. It will go blank momentarily then flash the # of errors, finally it will display the previously set temperature. Then it will calibrate itself.

-see if your temp works at Hi setting, your engine temperature shld be close to normal will you do this.

Cheers
