AC Heater Control
The AC heater control is the panel of knobs, buttons or switches you use to set fan speed, temperature and vent mode. We list 31 AC heater controls from $22 to $667 for 1983-2014 vehicles. Motorcraft makes most of them, with strong coverage for the Ford F350, F150, Focus and E250, plus the Volkswagen Jetta and Cadillac Escalade.

Signs the control has failed
The heater control sends your settings to the blend door, mode door and blower. Depending on the vehicle, it uses cables, vacuum lines or electrical signals, and some units are full electronic climate modules.
Common signs include buttons that do nothing, a display that stays dark, airflow stuck on one vent, temperature that will not change, or backlighting that has failed. Before replacing the control, rule out a blown fuse, a bad blower motor resistor or a failed blend door actuator, since they cause similar symptoms.
Matching your panel
Heater controls vary by trim, even within one model year. Manual and automatic climate control, single or dual zone, rear defrost and heated seat buttons all change the part number.
The best check is the part number printed on the back of your old unit. Compare the button layout, connector count and mounting tabs with the listing photos. Brands here include Motorcraft, AC Delco, Genuine, Vemo and CRP.
Install and setup
Disconnect the battery before removing dash trim, especially near the radio and airbag wiring. Use plastic trim tools to avoid cracking the bezel.
Some electronic controls need a calibration step after install so the module can relearn door positions. This may run automatically with the ignition on, or it may need a scan tool. Check the service manual for your vehicle and read the fitment table carefully before ordering.
AC Heater Control questions
Why does my heater control light up but nothing changes?
The control may be sending signals but a blend door actuator, vacuum line or blower motor resistor may have failed. Test those parts before replacing the panel.
Can I swap a manual heater control for an automatic one?
Usually not without other changes. Automatic systems use different sensors, actuators and wiring, so stick with the type your vehicle came with.
How do I find the right heater control for my truck?
Remove your old unit and read the part number on the back. Then match it with the fitment table for your year, model and trim.
