My heater is on even though the control calls for air . Is there a usually broken item for this, A rheostat or module and where is it located? Truck has 110,000 miles on it TIA for your help


Could be either the Blend door or the water valve.

Cheers

My 2000 has had 2 blend door actuators so far.
