You can TRY to remove glovebox and all wiring and nesicary panels but it would probably take the same amount of time as it would to do the job properly.
sory.

Air blend actuator 2000 ford explorer is not working?


First, insure you do not have a vacuum leak or bad vacuum check valve. If this is all good, you may have to change actuator and every model has a different way to access this--some require dash removal. If you must do this, get a shop manual as the air bags CAN BE VERY DANGEROUS!

1997 ford explorer... My heater is only blowing cold air. The heater core and tubes get warm to hot, the temp control knob works. Is there any time of short term quick fix i can do till i have the money to...


If the thermostat is not opening (coolant circulating) and getting coolant through the inlet hose of the heater core you will not get any heat. If the thermostat is working then the heater core is clogged. Some folks take the heater inlet and outlet hose off and flush each end with a garden hose, got to give it enough pressure to unclog the core.

2003 ford explorer no heat and clicking in dash board


Clicking sound is your blend door actuator stripping it's gears and failing to open the door that directs the blower air through the heater core. Follow the sound to the actuator and remove it. Install a new one. You may have to remove some panels to get to it. The part is shown below and costs $32 at autozone. Please let me know if you have questions.

The heat in my 2006 grand prix will not get hot. We replaced the thermostat and got nothing. So I got the radiator flush and force filled again. Still nothing. Temp of the motor still gets to the middle,...


Are the 2 tubes that go to the heater core getting hot? If so, then the blend door is not opening to allow heat to get to the cabin.

Possible vacuum motor problem, either disconnected, or the controller for the blend door is broken is likely problem.

Troubleshooting by Symptom Poor Heater System Performance CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.
  1. Start the engine.
  2. Idle the engine until the thermostat opens (upper radiator hose will be hot) Is the engine at normal operating temperature (approx. 200° F)? If yes, go to the next step. If no, go to step 16.
  3. Set the mode selector to FLOOR mode.
  4. Set the heater control selector to the warmest temperature setting.
  5. Set the blower speed the lowest setting.
  6. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 14. If no, go to the next step.
  7. Set the mode selector to PANEL mode.
  8. Select the maximum blower speed.
  9. Select the warmest temperature setting.
  10. Place a thermometer into the center I/P PANEL air outlet and affix a second thermometer to the heater core outlet heater hose.
  11. Record the temperature at the center I/P PANEL air outlet and at the heater core outlet heater hose. Are the two temperature readings about equal? If yes, go to the next step. If no, go to step 13.
  12. Inspect and repair the cowl, cowl area, recirculation door, and the HVAC evaporator/heater core case for cold air leaks. Repair any problems found, go to step 17.
  13. Inspect the temperature door operation. Repair any problems found, go to step 17.
  14. Turn OFF the engine. Back-flush the heater core. Start the engine. Select the FLOOR mode and the lowest blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Is the inlet heater hose feel significantly hotter than the outlet heater hose? If yes, go to the next step. If no, go to step 17.
  15. Replace the heater core. When the repair is completed, go to step 17.
  16. Check for low engine temperature problems, Repair or replace as needed, go to step 17.
  17. Operate the system in order to verify the repair. If the system operates properly, the repair is complete. If the heater still does not work properly, repeat the entire procedure.

  4. Disconnect the vacuum lines from the defroster and panel mode vacuum actuators and position them out of the way.
  5. Remove the 3 heater-A/C unit cover attaching screws, fastened upward at the defroster outlet chamber.
  6. Remove the 2 heater-A/C unit cover attaching screws, fastened upward at the air inlet plenum.
  7. Remove the 11 heater-A/C unit cover attaching screws, fastened downward into the housing. Then lift the cover from the heater-A/C unit.
  8. Remove the old heater core from the case. To install:
  9. Install the new heater core into the heater-A/C unit case in the same position as the old one.
  10. Place the cover onto the case and secure in place with the 11 retaining screws.
  11. Install the 2 heater-A/C unit cover attaching screws in the air inlet plenum.

The auxiliary A/C and heating system has the following features:
  • The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
  • The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
  • Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
  • The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
  • Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
  • Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.
---------------------------------------
I would say the auxiliary mode door (#4) electric motor is not wokring.
