Either the blend door, or blend door actuator has failed. To verify its operation requires removing the actuator itself, to see if the blend door moves freely. If it's broken, the insrtument panel will need to be removed in order to service. Move the temperature selector between full hot, and full cold with the electrical connector still connected to the actuator, but disconnected from the heater box. If it doesn't move, it's either the temperature selector, or something in the circuit, or the blend door actuator itself has failed. E-mail me if you require further information.

It controls a little door in the vent that mixes cold and warm air. Yours is a pot that controls an electric actuator that determines what position the door is in. It could be a bad control, loose wire, blown fuse, a stuck door or bad actuator.Why is there always some halfwit that says "Check the thermostat"?

On one of the heater hoses up toward the firewall on the right side you will See a valve that is hooked into the heater hose. This valve has a wire hooked to it that moves a lever back and forth on the valve. It probably has come off. Simply put it back on. You may have to make a minor adjustment on clamp that holds the wire. The wire only sits on the valve lever. Check it out--it's an easy fixIt got really cold, and now my car won't start.
