Heater not blowing warm air

[quote:ada2fa564b="bill99bass"]I have a Ford explorer 4wd with the 4.0l sohc it has about 173,000 miles. I have replaced the temper ture switch and check the heater core both are fine. You can change the air flow from defrost to feet but still blows cold[/quote:ada2fa564b]



Do u hear clicking when changing from hot to cold and back
U may need the blend door motor
Behind the clove box up on the HVAC box
Good luck

Hows the coolant level in the radiator-heater core/hoses do they pass coolant. Could be a blend door or an actuator. What year is it and I'll look into it.

it is a 1998 I use to hear a clicking noise but not any more. The cooliant level is full in the rad. and overflow

You must be talking about the blower motor relay its in the engine compartment in the power distribution box.
