Can someone tell me how to remove my Heater AC control assembly part # AC Delco 15-72956 to put a new one in my 03 Silverado?

 

1 Apply the parking brake to prevent the vehicle from moving.

2. If equipped with an automatic transmission, move the shift lever all the way down to last gear. Dont start vehicle just put key in run position.

3. Tilt the steering wheel to the full down position.



4. Pull gently rearward on the corners of the bezel from the instrument panel (IP) assembly.

5. Remove the bezel.

6. Unscrew the HVAC Module and Unplug.

 

Thanks for the info. Looks easy enough.

 

I changed the HVAC module and now I can adjust the temp and use all controls but it still only heats when set on 90 degrees. can you help?

 

Bad temp door actuator.
