Heater is not blowing hot air, sometimes warm and blend doors are clicking even when heater is off. Repair at Ford dealer is very expensive. was considering doing it myself what do I need as far as parts and manuals?

    No. I don't think that's it. I think maybe I need a new heater core because the air is just not hot and I need to replace whatever part it is on the blend doors that is not catching and is clicking.

  • karenkornbau Jan 29, 2009

    Ok I will check that, but what I am hearing is like a motor going around and around with a loud clicking as if something is not catching. This happens even with the heater turned to off.

    the blend doors are generally operated by vacuum. feel the hoses going to the heat core (from inside the engine compartment and see if they get hot... inlet and outlet (don't worry which is which) they should both be hot.

    just to clarify.... the issue is that the blend (heater vents) are not opening properly and then you aren't getting much heat ?

This is a huge job I don't recommend it unless you have a whole day and experiance or 3 to 4 days with none and lots of patience. The dash needs to come out to replace that blend door and actuator. I would caution agianst attempting without experience.

NO, the blend door motor is accessable (on my 96 Explorer) if you pull the glove box out. You'll see the Black "box" / "Door" and it's about the size of a large wallet. The problem is the metal portion wears out the plastic gears over time. Just fixed and took about 1 1/2 hours.

    For the Blend motor replacement, there should be 3 bolts (2 in the front and 1 in back which is kind of hard to get to & hard to see).. I think mine were 9/32" bolts.



    If anyone can help on my "Low Beam" light problem, I'd appreciatte it. I think it may be the Multi Function Switch (Lever to switch between low/hi beams) but I have no clue to get it out.

My 2002 ford explorer the temp. Control knob when you change it it makes a loud clicking sound and it will no longer blow cold air only hot.


there is an actuator that controlls a blend door that is called a blend door actuator. This "door" is inside the evaporator case and it opens and closes to divert air over either the evaporator (for air conditioning) or the heater core (for heat) and can be somewhere in between for warm air. your temp knob sends an electric signal to this actuator to controll that door. the actuator has plastic gears inside of it that can become stripped of its teeth causing a "tapping" sound. These trucks comonly have this problem. The actuator is screwed on to the evaporator case and the blend door actuator is a mounted on top either behind the radio or the glove box. It;s about the size of a deck of cards

Just purchases a 1997 Ford Explorer AWD V8 and the heater isn't working. Put anti-freeze in it last night and it started to get warm. No such luck this morning, it's blowing cold air. The outside...


OK, recheck the anti-freeze level and fill if necessary. There may be a leak in the system.
If it is filled up to capacity (also check that the upper radiator hose is full of fluid by squeezing), then the next thing to check is the two heater hoses that enter the firewall for the heater core. If they aren't getting hot at normal operating temperature, the heater core is plugged up and will have to be flushed or replaced.

If the heater core hoses are hot, then a blend door problem exists for shuttling hot air from the heater core to the interior of the vehicle.

Good luck on this repair.

MY 1998 FOR TARUS HEATER WILL NOT WORK.WAS DRIVING


It is most probably the problem with blend door or blend door actuator. But just in case I would suggest to follow the entire procedure:

First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is warm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest flushing the heater core.

Blend Door on 98 Ford Explorer


the blend door is roughly in the middle of air distribution Plenum assembly between the heater core and the AC evap core, it either directs air through the heater core or the AC evap core or mixes air from both.

Heating...burrrrrrrrr


The clicking is the air temperature blend door motor, most likely the motor will have to be replaced the blend door checked to make sure it moves freely, this repair requires the removal of the dash assembly.
