SOURCE: Heater/AC control no longer allows change in temperature

You have one of two possible problems.

1) The temperature shaft retention nut is loose behind the knob

2.) The wires to the potentiometer part of the temperature may be broken.

Either one is common to this vehicle. The replacement of the AC controller is about 900 dollars. If the wires are broken, they can easily be reattached to the circuit board via soldering. What you would have to do is remove the control box from the dash, and disassemble it. Once the unit is apart, there are 3 wires from the temp knob to the circuit board that need to be re-soldered. The unit CAN be repaired, as opposed to the expense of replacing it.

SOURCE: tempature control knob

There's a white lever under the dash near the steering wheel. You can change from heat to cold with that instead of the knob! If you look under there you'll see it and just push it up for heat pull towards yourself for cold.

SOURCE: the heater control knob will

Cable is probably kinked or slipped adjustment. There are 2 cables connected to the knob. One move the blend door in the heater box to make the air flow thru the heater core, and the other cable opens a valve in the heater hose (engine compartment) to let the hot engine water into the heater core. Check both cables for kinks and fix and kinks. It is still doesn't work, first disconnect both cables at the blend door and valve and check the door and the valve for proper operation (can you open and close them by hand?--if not, these must be repaired or replaced), then, if good, adjust the cables according to this procedure from autozone.com:


CONTROL CABLE Adjustment

  1. Under the hood, open the clamp and disconnect the heater control valve cable from the arm.
  2. Under the dash, detach the air mix control cable from the clamp. Pull the cable from the control arm.
  3. Position the temperature control at MAX COOL.
  4. Turn the air mix control arm counterclockwise until it stops.
  5. Attach the air mix control cable to the arm.
  6. Snap the air mix cable hook into the cable clamp.
  7. Under the hood, turn the control valve to the fully closed position.
  8. Install the heater valve cable to the arm.
  9. Gently pull on the cable housing to remove any slack.
  10. Insert the cable into the clamp.

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.

Why doesnt control f150 ford turn from heat to ac on f150 ?


It is possible that your control head is not working properly. The center knob( temperature control ) may be positioning the temperature door to full heat. If you have all of the directional flows and the off position, this is probably the problem. You can remove the control head easily by removing the cover plate by pulling outward evenly at the control face. This will reveal 4 screws that hold the control in place. Remove screws and pull slightly out on the control head(do not pull out far as you could damage electrical connections and/ or vacuum connection. Temperature switch is held on by a single screw on the back of the control. remove screw, turn counter clockwise and pull control from the knob that is now holding the switch in place. Replace switch and assemble back into the dash, locate flat on the knob and the switch, align and press into place.

If you are in the South east Michigan area I will be glad to assist.

Check the blend door cable for proper attachment to the control panel and to the blend door. Try opening the door manually to see the you can get hot air out. If not, the door may be broken inside the heater box. If yes, correct/adjust the cable attachment for proper operation.

REMOVAL & INSTALLATION

2003 mitsubishi outlander temperature control knob would get stuck while turning..and finally snapped off and broke


The source of the problem is not the knob it is the temp blend door binding. Putting to much stress on the knob. If you replace just the control head with the knob it will only break again. You need a dampener repair kit and to install you will have to remove the dash and heater core.this will slow you to access the door that is binding. Hope this was more help then it broke replace it.

is it the temperature control knob or the fan speed knob? the temperature control knob is hooked to a cable that operates a valve in the engine compartment. sounds like this is your trouble area...you can open the hood and locate the heater control valve near the firewall...have someone turn the knob to see if the valve lever opens/closes. if it does it is bad. if it does not move there is a problem in the dashboard behind the heater control unit.
