My 2010 taurus heat/ac control not working. Heat blowing at 90 degrees at all times but heat / ac control not showing on and can not shut off.

Disconnect the control unit wire harness and then plug it back in. Should do the trick, corrosion. Disconnect negative side of battery first.

Has heat but need to turn my control all the way up

Blower resistor controls the speeds of the motor, and if bad, may only run the fan on high. Easy to replace and visual exam will show if bad. Located under hood on heater box.

No heat coming from heat vents, blower works. i have change thermostat still no heat

Make sure the cooling system is full ... they can run with low coolant and not have it show on the temp gauge. Make sure the heater temp control actual opens the valve the controls the flow of coolant to the heater.

1 Answer

Heat (or lack there of)

The heat source for the fan is probably comes from the liquid coolant in the radiator. Since the temp gauge shows it to be warm, my assumption is that there is no hot liquid getting to the heat element in the AC/heat plenum.

Do the controls feel any different than they usually do? I'm assuming you have probably been using the system in the AC mode during the summer. I would try to see what happens when the different heater controls are moved. Somewhere there is a valve that is not being actuated, or a vent door that is not moving. My experience (personal) is that a door that controls air flow is not operating and that's because it has sat in one position all summer. Sorry I can't be more specific.

Hope this helps Good luck Loringh
