Heat always on high

[Bouche2210]

When ever the climate control fan is on the heat is on high no mater what the temp is set at. Unless the AC is turned on.

Sounds like your blend door crapped out on ya. You can either have the actuator replaced yourself or take it to the dealer. But let me warn ya, if you're taking it to the dealer, it's gonna cost ya a very very pretty penny.

Search "Blend Door" and see if what you read is what your problem is. Assuming you get only hot air in every position except for Max A/C, then your problem is the blend door.
