    Have '09 2500HD 6.0 work truck with standard climate control. The heat temp. control knob some times takes some playing with to get the temperature you want. Sometimes when you want hot air it is just warm even though truck is at 210 operating temp. If you turn it back n forth sometime it gets hotter. I am thinking it may be a a servo motor but read some require complete dash tear down :mad:

    Anyone experience this or know if the temperature servo is replaceable without tearing dash off?
