    my switch does not control the vents

  • 15frit Dec 04, 2008

    The speedometer was the first to go. It was out for 6 months. Now all the instruments are out including gas gage and temp gage. Oddly enough, the tach still reads OK. Any help would be appreciated.

    I just bought a Bonneville GXP in Sept of 08 and after a month, I have the same problem with the instrument panel. The fuel guage was the first to go. Then the speedo, tach, went inop and I'm not sure if the temp guage is working correctly or not. What in the world is going on with these instrument panels? The heads up display works fine according to the OBDII scanner I have installed on it. It still racks up the miles like it should but I need to know how to fix this!! ANY HELP??????

Have you checked how low the freon is in the compressor of the air conditioner? Sometimes if it is too low the compressor won't pick it up and therefore, the fan won't work. on any speed and if it does it won't blow cool. Hope this helps.

Controls for ac not working on 1998 buick century


see this steps and fix it. God bless you

Start the car and turn the air conditioning on. Allow the engine to run a few minutes so the air can cool. Check to make sure you have the proper buttons selected. This simple step may uncover the root of the problem.

  • 2 Adjust the air controls on the dashboard to see how they are working. If the controls move the way they should with the proper amount of resistance and stopping in the right places but have effect on the air, then the problem may as simple as a blown fuse. If the controls are not working at all, then the problem is in the control panel.
  • 3 Get to the fuse box in a Ford Explorer by removing the instrument panel to the left and slightly below the steering wheel. There is a fuse remover provided in the fuse box. A blown fuse will have a broken wire in it. In a Ford Explorer, this fuse is red number 10.
  • 4 Find the control panel by prying off the top instrument panel around the air conditioning temperature controls. Unscrew four screws, one in each corner, and remove the temperature control panel. Unplug four electrical connectors and one vacuum hose to the control panel.
  • 5 Listen for the blower motor to be properly working while the engine is running and the air conditioning controls are turned to high. Adjust them from low to high to make sure the blower motor noise increases and decrease accordingly.

    Hi I,ve got a 2000 Jeep Grand Cherokee, the problem I,m having is when I turn on the heating fan i get a mist or steam coming out of the vents smells like coolant could this be a heater core problem ,...


    Yes, your core is leaking. The core is in the box under the dash. The procedure is quite involved. I will attempt to paste from autozone.com below:
    1. Before servicing the vehicle, please familiarize yourself with safety procedures.
    2. Disconnect and remove the negative battery.
      CAUTION After disconnecting the negative battery cable, wait 2 minutes for the driver-s/passenger-s air bag system capacitor to discharge before attempting to do any work around the steering column or instrument.
    3. Drain the cooling system into a clean container for reuse.
    4. Remove the instrument panel by performing the following procedure:
      1. Turn the steering wheel in the straight-ahead position.
      2. Remove the A-pillar trim from both sides of the vehicle.
      3. Remove the top cover from the instrument panel.
      4. Near the windshield line, remove the 4 instrument panel-to-chassis nuts.
      5. Remove the scuff plates from both front door sills.
      6. Remove the trim panels from both sides of the inner cowl.
      7. Remove the floor console.
      8. Remove the fuse cover from the junction box.
      9. Remove the instrument panel cluster bezel.
      10. Remove the steering column opening cover from the instrument panel.

        Both lower clock spring connector receptacles Left multifunction switch receptacle Right multifunction switch receptacle Both ignition switch receptacles Shifter interlock solenoid receptacle Sentry Key Immobilizer Module (SKIM) receptacle, if equipped
      14. Turn the ignition switch to ON position; then, release and remove the shifter interlock cable connector from the ignition lock housing receptacle.
      15. Turn the ignition switch to OFF position; this will prevent the steering wheel from turning and the loss of the clock spring centering following steering column removal.
      16. Remove the 4 steering column-to-instrument panel steering column bracket nuts.
      17. Remove the steering column from the instrument panel.
      18. Disconnect both side body wiring harness bulkhead connectors, the Ignition Off Draw (IOD) wiring harness connector and the fused wiring harness connector from the junction block connector receptacles.

      21. Disconnect the instrument panel wiring harness-to-floor console retainers.
      22. Remove the instrument panel-to-floor console bracket screws and the bracket.
      23. Remove the driver-s side floor duct-to-heater/air conditioning housing assembly screw and remove the duct.
      24. If equipped with a manual heating-air conditioning system, disconnect the vacuum harness connector from behind the driver-s side floor duct.
      25. Remove the instrument panel steering column support bracket-to-driver-s side of the heater/air conditioning housing assembly screw
      26. Remove the instrument panel steering column support bracket-to-intermediate bracket screw.
      27. Remove the instrument panel steering column support bracket-to-driver-s side cowl plenum panel nut.
      28. Remove the 2 instrument panel-to-driver-s side cowl side inner panel screws.
      29. Remove the instrument panel end cap.
      30. Remove the lower right center bezel from the instrument panel.
      31. At the passenger-s side cowl side inner panel, disconnect the instrument panel wiring harness bulkhead connector from the lower cavity of the inline connector.
      32. Near the right side cowl inner panel, located under the end of the instrument panel, disconnect both halves of the radio antenna coaxial cable connector.
      33. Disconnect the 2 instrument panel-to-heater/air conditioning assembly wiring harness connectors.
      34. At the passenger-s side, remove the 2 instrument panel structural duct-to-heater/air conditioning housing assembly screws.

    No heat or cold air will come out of my2004 Mitsubishi Galant. I took off the dash panel behind the glove box to get to the Blend Door Motor, but after turning the air from hot to cold at various speeds,...


    Does the air blows through the dash board vents. Does the selector is functional, that means you can force the air stream through wind shield, or vents or down to the legs. If these things are OKthen check CONTROL PANEL.
    Remove the trim plate surrounding the center instrument panel. Detach the electrical connectors and remove the control panel.

        Parking brake release handle linkage rod from the parking brake mechanism located on the left cowl side inner panel. Instrument panel wiring harness connector from the parking brake switch located on the parking brake mechanism. Three wiring harness connectors (body wiring harness, headlight, dash) from the 3 junction block connector receptacles located closest to the dash panel. Head light/dash-to-instrument panel bulkhead wiring harness connector screw and disconnect the connector. Instrument panel-to-door wiring harness connector located directly below the bulkhead wiring harness connector. Infinity sound system wiring harness connector (if equipped), located at the outboard side of the instrument panel bulkhead connector. Stop light switch electrical connector. Vacuum harness connector located near the left side of the heater/air conditioning housing.
      8. Under the passenger-s side of the instrument panel, disconnect the radio antenna coaxial cable connector.
