SOURCE: heater blower motor works intermittently

I would replace the blower motor, this sounds like a motor brush problem inside the motor itself.

Look next to the blower. You can remove the panel under the passenger side. Go through the glove box and move it down out of the way to access the electrical connector. Then remove two bolts and the electrical connector.

SOURCE: NEED TO REPLACE BLOWER RESISITOR. FAN ONLY WORKS ON HIGH SPEED

Under the dashboard on the passenger side you will see the blower motor. Near the blower motor inside the air duct is the resistor. It should be held in place by two screws. Hope this helps. Good luck

Pontiac g6 2006 heater/ac fan doesnt work on #3 speed setting, fan made squealing bearing noise for a while but quit, also inside/outsied air vent switch vent makes clicking noise when set to outside air


you will need to replace the blower motor as it has probably siezed going by the squealing noise you say you heard.i`m assuming this has more than 3 speeds for the fan motor.if it wasn`t working on one speed then you probably have a bad blower motor resistor that will need to be replaced as well so you will have all fan speeds.this is located in the air duct housing near the blower motor and will have about 6 wires on it.some of these on under the hood on the firewall anywhere from the passenger side to the center of the firewall.not sure about the vent switch.if the vent switch is moving the doors and you hear a clicking then you may have a vent door problem that the door pivot is worn.

Why did my 02 trailblazer stop blowing ac through all the vents when, switched to heat it still doesn't blow air through the vents? I have no air flow what's wrong?? :(


First check all the fuses. There should be one for Blower or Heater. If all fuses are good, It is likely a bad blower motor or a switch to turn on the blower motor. Try all fan speeds in non auto mode and see if you get any activity. If you get activity on some fan speeds then it is the switch or sometimes called the blower motor resistor. If no activity, its time for a new blower motor. They are under the dash usually on the passenger side, shouldnt be too hard to pull out.

2006 Ford Mustang blower fan works on high only -


Need to change the switch that works high, medium, and low. It is a separate switch mounted usually behind the glove box or somewhere under the dash. Hope this helps, Mitchell.

Does my 06 Trailblazer have a cabin air filter


{: ) There's no cabin air filter installed. If your concern is a low air output, I suggest you remove the front blower motor and clean it with pressurized air. Maybe the blower fins have accumulated dust or debris and this will diminish the air output. Also check the inside of the housing once you removed the blower motor. Sometimes some dry leaves or matter accumulate on the evaporator wall, hence, blocking some of the air. Good luck.

The fan will not kick on...on my 2006 Trailblazer. Fuses look good along with the relays. The compressor seems to be working fine. Can't get air to flow through the vents.


The list of things that could be bad; blower motor, blower motor resistor pack (control module), resistor pack wire harness, fan selector switch and fuses. You say the fuses and relays look good, what does that mean? And which fuses did you check? Fuse for blower is in the underhood fuse panel and is #35.The relay is inside the control module, so you can not see it.

Ac fan motor doesnt work on low speeds only on


I will assume the heater fan also doesn't work on low. You will need to replace the fan speed selector switch
