Hi Ron,
Apparently Ford is having a real hard time with this due to the amount of times I have answered this question this week. Hope they figure it out! Check the blend door actuator located under the glove box. Make sure the wiper (door) moves freely when disconnected from the actuator arm. This is different than the air direction door. Ford must be selling a ton of these. If you need more info, I have pics that I can send. I will need your email address.
;;; email ron_crick@yahoo.com ok, i understand how the blend door can affect the heater.. what i dont understand is how it would keep the AC running when its cold outside and inside the car and the temp is set for 90 and the direction is set for vents or floor, and not AC?
AnswerHi Ron,
Most of the time when I get this question the complaint is blows cold air. I didn't realize your compressor was running also. In this case you may want to look at the dash control unit. It is possibly sending incorrect data to the computer. Pricey unit at $533.35. Book time to install it is 1.3 hours. I was considering the "in cabin" temp sensor, but you indicate that there are no codes and that would set a DTC. I am afraid that the control unit is the culprit.
