I will try to answer and offer you a couple of choices based on 2 different potential problems.

The blower motor resistor is the control for both the heater fan blower and the A/C since they are the same blower motor. It is the boost that you need to feel either heat or A/C through the vents. The part can be traced from the heater blower wires under the hood to a control about the middle of the Firewall. 2 bolts hold it in place with 1 connector wire. But a heater line will likely block access to switching the part. It is often a part that tapping will start it working again.

Another A/C intermittent problem is low Freon. A certain pressure will engage the A/C compressor switch. Since outside air temperature can boost the internal pressure remaining in your A/C system, every time it expands the Freon; your system may work.

SOURCE: Can't change air flow direction on ac/heater control. Only blows up to windshield.

It will be a cable that will be disconnected. or broken. Youll have to take some of the dash apart to see the cable and follow it to the switch. Dont be affraid to take some things apart and when you cant see, use a mirror to help you see behind the dash. work the control and watch the action. You will fix this dont get frustrated. good luck

I have a 2001 ford expedition my ac works just fine but the heater does not work at all. Any suggestions?


Could be a couple of things. Newer vehicles have a heater control valve inline with the hoses that lead to the heater core. Another thing to check would be your coolant level. If it is low air can become trapped in the line and restrict flow to the heater core. Be careful when checking your coolant level it is a pressurized system.

1988 Ford Exppedition heater in the front will not work


I ASSUME THIS IS A 98, THIS PROBLEM IS CAUSED BY A PART CALLED AN "AIR TEMPERATURE CONTROL BLEND DOOR ACTUATOR MOTOR" THIS MOVES A DOOR BETWEEN THE COLD AIR FROM THE AC AND THE HOT AIR FROM THE HEATER CORE, YOU WILL NEED TO REPLACE THAT ACTUATOR. .

Ac and heater not working. New Heater core and


You need to but a scanner on the computer and activate the AC. If it does not activate you may have a bad PCM. Also if the pressure in the AC is low it will not run. Also you have a AC relay in the engine fuse box.

Now for the bummer part. I have this same truck. Replaced heater core and I didnt get the blend door quite on track and it jammed. I had to take the dash off again. Also your center heat control may be bad.

I don't think these two problems are related. Even without AC your heat should work. Do you have rear climate control also. See if that works. If it does you may have a jammed door for the dash area

Have a 2000 ford expedition and the ac in the front blows hot but the rear ac works fine. what could it be


Listen and see if the vent flap is moving from the hot position, to the cold position. If that's working then the evaporator may be clogged. It sits inside the same box that the heater core is inside of and if it becomes clogged with hair or dust, then it wont allow the blower to blow through it. But it would then bring hot air through the vents because the heater core is there too.
