Hi,

Cadillac Mechanic: Eric, Automotive Repair Shop Manager replied 4 months ago

HI,

Ok, with separate temperature controls, it has a left side and right side temperature blend door. If neither side is heating up until you turn the temperature on both controls to 90 degrees, this is a climate control unit(the dash control) that is faulty. While I have seen the left and right temperature blend door actuators fail at separate times, I have never seen both fail at the same time.

The climate control unit will need to be replaced to resolve this. It is a fairly easy procedure. see attached directions

I made a mistake i have one temperature control
Cadillac Mechanic: Eric, Automotive Repair Shop Manager replied 4 months ago

HI,

Ok, most likely the actuator which is located behind the glove box, see attached

You will want to test for voltage on the grey with black wire and the white with black wire as you adjust the temperature. If voltage is present, replace the actuator
