Question about Ford F-250

1 Answer

The heat doesnt work and we think the heater core went bad. Is there a way to know if it is just the lever to open the vent or is the actual heater core broken.

Year make and model?

When you turn the heat selector from hot to cold you should here a difference in the way the air sounds when it comes out of the vents.

If the heater core is plugged than usually one of the heater hoses will feel a lot hotter than the other. If this is a taurus they are well known to plug the heater cores. I would bet that the coolant looks like mud also.

I have had a good success rate back flushing heater cores with a garden hose. Sometimes it only takes a couple of minutes to get all the debris out and some it has taken a couple of days of repeated tries to get them clean.

Ac works fine, air direction control works fine no heat,from vents both heater hoses warm

possible climate control problem or the acctuator that opens the door for air flow from heater core. Check for a vaccum leak in the engine compartment or a bad diaphram on the acctuator, and even a bad cable from the control lever/knob.

This problem is caused my the blend door actuator motor, the electric motor turns to allow the flap to open either to cool or heat and then through the vents. The problem has been either the motor is going bad or the actual motor stops working. There are small plastic gears that strip in the motor causing this. I have replaced several in the rear unit. The front one is under the dash next to the heater core. The dashboard must be removed. It is a big job.
Please rate me and let me know if this helped.

Heater not working

I would check if your vent to the outside is open. If it is I would check the vacum hose that controls the vent to open and close.
