Control not working. Blower only works in the 3 4 setting.

Customer Question
Heather control not working...

Heather control not working. Blower only works in the 3 4 setting. Also air will only come out of the AC vent. No floor heat or defrost. I think I need to replace the control module.

Mechanic's Assistant: Have you checked the coolant level? Have you checked to make sure the thermostat is working?

Yes. There is heat & AC.

Mechanic's Assistant: What is the model/year of your Ford?

05 explorer

Mechanic's Assistant: Are you fixing your Explorer yourself? What have you tried so far?

Probably gonna replace the 3 switch cluster.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Nope. It seems like the best place to start because the 3 switch cluster has problems with 2 of the 3 switches.

Hello and thank you for your question. My name is James.

Since the a/c and temperature control work, we know there is sufficient power and ground to the control panel. The panel blend switch and blower operate separately, though they share the same power source, so you are correct in replacing the switch and retesting.

James.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
