    the lot is paying for it,i think the core is filthy again,i think they flush with out a machine the rad was so dirty the rad shop couldnt clean it so they replaced it so do you think the core should be taken out and cleaned or replaced again or maybe the control valve what ever that is

    My personal belief as an old shade tree "mechanic" is that it has to be electrical and has something to do with the installation of the new ignition switch module that was installed. Maybe a coincidence, but that's my idea

I have changed the radiator, heater core and the thermostat in my 1997 ford F150 but I am still blowing out cold air


THE TEMPERATURE BLEND DOOR STUCK OR BLEND DOOR ACTUATOR MOTOR FAULTY,YOU NEED TO DO A EATC DIAGNOSTIC TEST TO GET FAULT CODE SEE WHY YOU ARE NOT GETTING HEAT.TO DO A DIAGNOSTIC TEST FIRST WARM ENGINE UNTIL IT GET 120 DEGREES.WITH ENGINE OFF IGNITION SWITCH ON SIMULTANEOUSLY PRESS OFF AND FLOOR BUTTON THEN WITHIN 2 SECONDS PRESS AUTOMATIC BUTTON SELF TEST TAKE UP 20 SECONDS INDICATING BY BLANK DISPLAY WINDOW ON THE EATC MODULE. IF DISPLAY IS BLANK FOR MORE THAN 20 SECONDS OR IF CODE 888 IS DISPLAYED GO TO EATC SYSTEM TEST UNDER TESTING IF NO CODES ARE DISPLAYED AND SYSTEM IS NOT OPERATING PROPERLY GO TO SYMPTOM DIAGNOSIS IF CODES DISPLAY RECORD CODES. BEFORE TURNING IGNITION OFF EXIT SELF DIAGNOSTIC.BY PRESSING DEFROST BUTTON EXIT THE SELF DIAGNOSTIC PRESS BLUE BUTTON. IF ALL FAIL LET A GARAGE CHECK IT OUT.BUT ALSO CHECK COOLANT SYSTEM IF COOLANT SYSTEM VERY LOW YOU HAVE NO HEAT PROBLEMS.

Heater blows cold air what could be the problem?


There's a lot of this going around! The first check you should make is the coolant level. If coolant is low, then it can't reach the heater core to provide heat to your cab.

1999 ford f150 , after engine warms up , heater only blows warm air


Check the hoses to the heater core and make sure they aren't deteriorated. Also, it might be worthwhile to clean and flush the cooling system.

It's possible there is a problem in the controls for the air conditioning system, too. The various valves in the ducts are vacuum controlled, and if a leak develops, it's possible that cold air is being mixed with the heated air.

1997 F150 heater problem


your problem is caused by the air temperature control blend door actuator motor being defective, the little motor moves the door that gives either hot air or cold air or a blend of the 2.
