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.

Where is the air and heat blend motor on a 2000 dodge dakota?


Hi Sharon, I'm glad to help. Your 2000 year doesn't have a motor for the temp door. It operated by a cable running from the control head to the temp door and you work it manually. If you can't control the temperature from hot to cold, sometimes the cable come off or breaks. Here how you can see the cable to see if its working. Remove the radio and right behind it you will see the cable attached to the door, while watching it move the temp lever from hot to cold and watch it. If it is moving then its most likely out of ajustment. If it is not moving, then you'll need a new cable. Just in case it is moving, I'm attaching the instruction on how to adjust it below. Hope this helps and have an awesome day Sharon!



TEMPERATURE CONTROL CABLE

Any time the heater-A/C control or the temperature control cable are removed and/or replaced, the following procedure must be performed.
  1. The temperature control cable housing and core must be installed at both the heater-A/C control and the heater-A/C housing ends, and the heater-A/C control must be installed in the instrument panel. See Heater-A/C Control and Temperature Control Cable in the Removal and Installation section of this group for the procedures.
  2. Rotate the temperature control knob on the heater-A/C control so that the knob pointer is in the 12 o'clock position.
  3. Pull the temperature control knob straight out from the heater-A/C control base until the perimeter of the knob (not the knob pointer) protrudes about 6 millimeters (0.25 inch) from the face of the control base.
  4. Rotate the temperature control knob to the 1 o'clock position. Push in on the knob slightly and continue rotating the knob to its full clockwise stop. The knob pointer should be aimed at a position about 8 millimeters (0.315 inch) beyond the end of the graduated red strobe temperature control graphic on the face of the heater-A/C control base. If the knob is not pointed to the correct position, go back to Step 2 and repeat the adjustment procedure.
  5. Rotate the temperature control knob counterclockwise until the knob pointer is in the 12 o'clock position again.
  6. Push the temperature control knob straight in towards the heater-A/C control base until the perimeter of the knob (not the knob pointer) is flush with the face of the heater-A/C control base.
  7. Rotate the knob to its full clockwise stop again. The knob pointer should be aimed at the end of the graduated red strobe temperature control graphic on the face of the heater-A/C control base. If OK, go to Step 8. If not OK, go back to Step 2.
  8. Rotate the knob to its full counterclockwise stop and release the knob. If the knob springs back from the counterclockwise stop, the self-adjuster clip that secures the temperature control cable to the blend-air door lever is improperly installed. See Temperature Control Cable in the Removal and Installation section of this group for the procedures. If the knob does not spring back, the temperature control cable adjustment is complete.

Automatic temperature control it's bad burn on me, I order a used "ATC" automatic temperature control and still doesn't work check the fuses and relays still doesn't work


There should be some kind of valve that controlls the actual amount of coolant running through the heater core and there for controlls the temp. There may also be a door that might be stuck that controlls the amount of air traveling through the heater core.

Blower only works on high


Bad connection or blower motor resistor . GM Blower Motor Resistor Diagnostics by Wells

Do you know how to do automotive electrical testing ? Have a volt meter ? Know how to use a volt meter ? Videos on youtube .

Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3-voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12-volt control values represent the opposite limits of the actuator range of motion. The values in between 0 and 12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal sets to a value between 0-12 volts. Actuator shaft rotation is the results of a commanded position input by the vehicle operator. With a new actuator commanded value action, the maintained actuator control value is changed.

We have a 2004 X5 diesel , fan won't turn off even after key removed, have taken out 50amp fuse to stop it ! would apreciate a solution please


In these models the temperature control works till the normal temperature comes to the engine. So if there is failure of the temperature control sensors- Thermistor- or if there is fault on the temperature controller unit , the fan will be made to work on till the controller deactivates.
So you need to check for the input- temperature sensor, check any wires that had come off the sensor or the unit, check if the fan control contactor/relay has failed or jammed on contact.( relay).
Try and trace these lines , check the action of the relay when the fuse is put on, if you hear the relay clicking then it works and the control circuit can be the suspect.

Is there an adapter to convert an automatic temperature control to a manual one?


im afraid that you cant find any adapter to convert the system from auto to manual, the manual and automatic temperature control works completely different, the manual climate control controls the temperature and air distribution by vacuums lines and in the automatic climate control, controls the temperature and air distribution by a series of blend doors that works electronically
