Whyohwhy Posted January 12, 2021 Report Share Posted January 12, 2021 Trying to progress the poor heat and suspect my CCM is not working correctly. When I select any heat position and AUTO, the air conditioning bursts into life. What does yours do ? Link to comment Share on other sites More sharing options...
Ihatespeedbumps Posted January 13, 2021 Report Share Posted January 13, 2021 Selecting the auto function will cause the blower to go to high speed until the desired cabin temp is achieved. If you are only having trouble heating you may want to have a look at that heater core. They can become restricted and cause a poor heating concern. Becoming more common as these vehicles age.
