Heater problem
2000 Chevy Astro 225000 miles
----------------------------------------------------------------
the heater only works on defrost. The air coming out is nice and warm but I cannot get it to change from defrost to any other position.

May be a bad heater control unit...Pretty pricy if I remember right. It needs to be tested.
