The A/C blower can be accessed by removing the housing located behind the glovebox. The procedure is a little daunting, but can be done. Plus the smaller your fingers are the better. There are 4 screws holding the two halves of the blower box together. Feel around and located them before you start, this will give you a good idea which ones need to come out first. usually the top ones. The fan sits inside, so make sure theres no power to fan, or ignition, as it will cause you to have a very bad and bloody day.

I have a 2002 Grand Am SE, my heat works fine, temperature wise, but doesn't flow out of my vents very well. Whenever I turn the heat on I hear a loud humming/vibrating sound coming from my blower...

I had a very similar problem on a Buick recently. Like mine, your blower's fan blade assembly may have come loose from the motor shaft. There is a very small washer type clip that holds the fan blade part to the motor's shaft. Usually the whole blower assembly is pretty easy to get to and take off...usually. A lot of GM cars had the assembly accessed from the firewall behind the engine. You would need to pull the blower motor out and check the fan assembly.

2005 gmc denali ac fan will not shut off even with key off

Common problem.

If you have automatic climate controls, replace the blower control module mounted on the blower itself under the glovebox.

If you have manual climate controls, replace the blower motor resistor assembly, same location.

Remove the plastic skid guard under the glovebox to access the bottom of the blower motor. Remove the 2 tiny screws that attach the part. Then open and empty your glove box. Stick your finger in the access hole on the left side of the door, press the spring and the door will flip upside down. There you will have access to the wiring connectors for either part. Remove this, and the part should drop down. Very easy procedure.

Air only works on speed 5

If you have auto climate control, replace the blower motor controle module.

If you have Manual climate control, replace the blower motor resistor assembly.

Both are in the same place, on the bottom of the blower motor itself. Take off the plastic kick piece at the bottom of the glovebox to access the bottom. You'll see small screws holding the piece to the blower motor. From there, empty your glovebox and open it. You'll see an access hole to the left, stick you finger in there and depress the spring loaded piece to drop the door upside down. There you'll have access to the electrical connector from the blower resistor to the blower motor. Very easy job and is a very very common thing to go bad.

How do i replace a blower motor

I assume the blower is not running. The first thing to check is the fuse for the blower motor. This is either in the fuse panel under the dash or on the main junction box in the engine bay.

Next step is to check that the motor is actually getting power. You should be able to access the blower fan assembly from the glove compartment. The compartment door will probably need to be removed, along with some other dash parts. You should be able to see the AC evaporator unit, with the fan assmbly.

It's unlikely but not impossible that the motor has failed. There may be leaves or other garbage in the motor assembly. In any case, removing the assembly will allow you to clean and test it.

The more likely problem however is the blower speed 10W resistor has failed. Look on the assmbly for a removable panel with two or three wires. Remove this panel, and look for a large ceramic resistor. This sits in the air flow to keep cool, and adjusts the blower speed.

When this resistor burns out, the blower stops.

  3. If moved on early model vehicles, reposition and secure the A/C vacuum tank.
  4. Connect the blower motor cooling tube.
  5. Install the coolant recovery reservoir, then if equipped, install the VCM.
  6. Connect the negative battery cable.

  6. Remove the blower motor-to-case screws (the lower screw is on the bottom front of the cover).
  7. Disconnect the harness from the blower motor.
  8. Use a razor or utility knife to cut through the cover on the cut line as neatly as possible because the access cover has to be reinstalled.
  9. Starting with upper half of the cover, tear the remaining part of the access cover from the remaining portion. Then remove the lower half of the cover in the same manner.
  10. Remove the blower motor assembly.

To install:
