More than likely the teeth on the gear in the back of the unit are broken. you have to buy a whole new unit with all 3 controls. this will run about 130-150$

No heat. New thermastat, heater core flushed, good circulation. Has a rear heater.


Does blower motor work , air blowing out of ducts ?
Temperature blending is varied by the air temperature control door, which regulates the amount of air that flows through and/or around the heater core (18476) , where it is then mixed and distributed.
Movement of the control knob from COOL (Blue) to WARM (Red) causes a corresponding movement on the air temperature control door and determines the temperature that the system will maintain.
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the heater system is determined by the position of the temperature control knob (between COOL-BLUE and WARM-RED) of the heater control .
  • This control knob is connected to a potentiometer mounted in the heater control . This potentiometer is electrically connected to the electric blend door actuator that operates the A/C air temperature control door.

My 1998 gmc jimmy slt has a heating problem. The heater wont turn off. As long as the car is on the heater is on full blast. The fans work and everything knob wise works but the heater is always on.


The air temperature valve electronic actuator positions the temperature door according to the temperature setting of the temperature control on the temperature control knob. For the full COLD temperature setting, the temperature control returns approximately 12 volts to the air temperature valve electric actuator. When the temperature setting is changed to full HOT, the temperature door is moved to the warm position and the output drops to about 0 volts. For a temperature setting in the mid range, the temperature door is positioned according to the voltage supplied through the temperature control switch.

NO HEAT STUCK ON AC HEAR CLICKING IN CENTER CONSOLE


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Temperature knobs won't change temperature Chevy Tahoe


You likely have a HVAC control head failure. The rear heater problem is likely a door actuator, the rear wiper is likely a open wire in the door jamb in the top. The gauges are likely a cluster failure.

Air won't blow cold and the heat won't blow hot I know one works of the compressor and the other works off hot water in the motor it makes no since to me


Couple of things come to mind. You have climate control, so it could be that the temperature sensor is bad or the plenum door actuator is bad. I would lean more to the sensor, as the door usually is open or closed when it goes bad. This would leave you with cold or hot all the time. Also the climate control console could be bad. You can have this checked with a hand held computer.

I have no heat in my 2000 ford expedition. The blower motor works but only blows cold air. As far as i can tell the heater core hasnt been by-passed.


Time to either flush or replace the heater core as it may be plugged with rust build-up. I'm assuming the engine is running at normal operating temperature, if not then the thermostat may need replaced.
