The fan switch itself is a possibility, but there is also a resistor pack behind the glove compartment. Hi speed doesn't use the resistors, though, so if it doesn't run on hi, it narrows it down to the switch, the motor, the motor ground, or the blower relay, or any of the associated wire connectors.

Break Down And Replace The Blower Motor


REMOVAL

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIR-BAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY OR DEATH OR DEATH.

NOTE: The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.

  1. Disconnect and isolate the negative battery cable.
  2. Remove the passenger side cowl trim panel.
  3. Position the carpet to access the front upper screw that secures the air inlet housing.
  4. Remove the recirculation door actuator.
  5. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.
    1. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
    2. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and remove the lower HVAC housing.
    3. Push the rubber grommet through the opening in the lower air inlet housing.
    4. Route the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
    5. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing.
    6. Gently flex the recirculation air door downward to gain access to remove the blower motor from the HVAC housing. NOTE: To aid in installation, note the position of the blower motor mounting tabs prior to removal
      1. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as necessary.
      INSTALLATION

      1. Gently flex the recirculation-air door downward to gain access to install the blower motor into the HVAC housing.
      2. Position the blower motor to the HVAC housing and tilt and rotate the blower motor as necessary to install it into the HVAC housing.
      3. Align the blower motor mounting tabs to the locations noted during removal and install the three screws that secure the blower motor to the HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      4. Route the blower motor wire lead through the opening in the lower air inlet housing and seat the rubber grommet.
      5. Position the recirculation door pivot shaft into the lower air inlet housing and install the inlet housing.
      6. Install the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      7. Install the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing. Tighten the screw to 2 N·m (17 in. lbs.).
      8. Connect the blower motor wire lead connector to the blower motor resistor or power module, depending on application.
      9. Install the recirculation door actuator.
      10. Reposition the carpet.
      11. Install the passenger side cowl trim panel.
      12. Reconnect the negative battery cable.
      13. Perform the heater-A/C control calibration procedure.

Installed new blower motor. bearing shelled in old one. new motor won't blow. tested . it's good don't have power to moter. fuses good relay good. isthere a circuit breaker in wiring for b


I don't have a diagram for a 2008. On 2005 models the blower motor relay gets power from a 30amp fuse.
When the blower switch is in the high position the resistor is bypassed and power flows directly to the motor. The motor is grounded to the car.
The fan relay also gets power from a 7.5amp fuse and is controlled by the HVAC control on the dash.
Do you have power into and out of the relay?

Blower moter will not shut off when I turn the key off.


More than likely it's the blower motor resistor. Gm's wonderful electrical engineers decided it was a good idea to run constant power to the high speed fan relay which is part of the resistor assembly. When the relay stick the fan stays on. The resistor is located under the dash on the passenger side ne'er the blower motor. There is a plastic trim pannel that will need to be removed from under the dash in order to see it. It is typically help in place with two screws that you will need a 5.5mm socket to remove (yes it's a 5.5mm socket). Lmk

FAN BLOWER (FOR A/C AND HEAT) ONLY BLOWS ON THE HIGHEST SETTING. IS THERE A FAN SPEED CONTROL OR RELAY THAT CAN BE REPLACED, OR IS IT SOMETHING ELSE?


Hello leebarker
The blower moter switch or the blower moter controler can cause this
problem. Remove the plug from the switch, use a 12v test light to locate
the 12v power wire in the plug. Next with a small jumper wire bring power from the 12v contact to the low and medium speed contacts on
the plug if the blower changes speed replace the switch if it still only
has high replace the controler. The blower controler is located on the
passenger side end of the heat-a/c box near the blower moter.
By the way the key must be in the on position for this test.
I hope this helps. Good luck.

Replaced the climate control and blower wont work


f that just put power to the blower moter and see it it runs if you pull the relay jump a wire across the terminals with it out and add a ground wire to the case of the blower to another spot on the chasis if it still does not run your blower switch may be bad dont worry just run a toggle switch to a good blower moter

My heater and AC blower not working. Please help


In the fuse block,under the hood on top of the fender. Locate fuse #35 it's 40amp fuse for the blower moter. If the fuse is ok,there is another
common problem you can check. The blower moter resistor assembly,
located under the dash on right side. With a 12v test light check for
power to the blower moter from the resistor. If you have no power to the
moter, replace the resistor assembly. If niether of these works, I'll need
to know if you have climate control or manual control hvac. And for some reason, the wheel base. long wb or short wb. to dig any deeper.
But I hope one of the causes I've mentioned will cure the problem.
Good luck.
