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 ?

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.
