1973-75 Pontiac Grand Prix ATC (Automatic Temperature Control) A/C Heater Control Head. Comes with a nice used lens and knobs. THIS IS THE STYLE WITH THE TEMPERATURE DIAL.
IT WILL NOT WORK IF YOUR CAR IS NOT SET UP FOR IT. Includes the first section of the wiring harness (see pictures).
It has been professionally rebuilt, calibrated and bench tested by someone who has been doing it since the early 1990s. All levers are unbroken and slide smoothly. All switches have been acid cleaned/dipped, lubricated and tested to function correctly. All you need to do is install it in your car and use it. These old A/C & Heat systems can be very complex.
