SOURCE: 2006 Trailblazer AC fan

I believe you must be talking about the inside blower fan tht is not coming 'on'.
It could be the switch tht operates the fan, remove the switch and check for live wire if theres current over there, if theres current thn operate the switch and check other ports for continuity of the current flow.
Its better first though to check the fan itself, it could be faulty or jammed or the brushes wornout.Remove the fan and you can test it out with the help of the car battery and two pieces of wire one to + and the to - , if the fan works thn you will have to proceed further as mentioned above.
Hope this helps.

It may be the heater fan motor or connection to it .
I have replaced a lot of these that required a new connector to make then the original connector semi melted at the fan motor.

Your blower speed resistor has gone bad and needs to be replaced. You can pick one up at Auto Zone or Parts Source with the step by step instructions to getting the resistor replaced with common tools.

It is located under the glove box, way in the back of the passenger foot area. You'll need to remove 2 screws with a 7mm socket, and remove the plastic cover that covers the blower motor and another component box that I think controls the passenger airbag. After removing the plastic cover you'll need to side that passenger airbag module to the right so it pop off its mounting bracket and move it out of the way. That will give a better view of the blower motor. I highly recommend you also remove the blower motor itself because the Blower Motor Resistor is located behind it. I think you'll need a 5mm or 5.5mm socket to remove the 3 screws that hold in place the blower motor and 2 more screws for the Blower Motor Resistor... It's a cramped location to work in but if you have all the tools and enough lighting then it shouldn't take more than 30-60 minutes to do. The Blower Motor Resistor costs about $19-$25. Good luck

SOURCE: Bad Clutch Fan? Rear ac/heat don't work front only works on 4

The fan clutch isnt engaged at all times, therefore it may be normal to hold it in place (not recommended). On these trailblazer's 4.2L engine the fan clutch is electronically controlled. Usually when this vehicle's fan clutch malfunctions, there is a random ticking noise while idling or at a stop, also the "service engine soon" may turn on. As for the the fan speed problem, this may be a faulty blower resistor malf (typical) or climate control unit may be faulty. Hopefully this helps!!

On my 2006 chevy trailblazer My heater fan stopped and I received a P1400 error code . What caused the fan to stop?

The P1400 code is a heated catalyst so what is causing your fan not to work is either your temp sensor or a faulty wire somewhere running to the fan. Check the fuse or relays

AC/heat fan not functioning. Possible fuse or relay ??

I would check for 12 volts right where the motor plugs in. If the wires are purple and black, check the purple one for 12 volts with the fan on high. Fuse should be in the underhood fuse block if you have no power at the motor.

My blower fan isn't working

A mechanic would check for voltage at the fuse or breaker, the fan relay, the blower motor, and the resistor.

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.

Hi, the air conditioning in my '93 dodge shadow isn't working. The blower fan works and the heat works. But no a/c.

Look to make sure both ac fuse and relay are good and have good connection, then start the car and turn ac on any change? if not you probably don't have any Freon due to a leak in the lines attached to your ac.

Blower fan not working. AC still cooling. Not

Sure. But could also be fan switch or motor. Check with a test light to make sure where the voltage stops.

2006 Equinox blower fan will sometimes not come on, and other times just start working. A/C, heat, it doesn't matter.

There are two components between the heater/AC contol panel/module and the blower motor; a blower resistor and a High blower relay.The problem sounds like a connection issue(a wire is loose) or the relay is going bad.Have the voltage tested at the blower itself,at the relay and at the control panel.Do this when the blower is not working.Wherever there is no voltage when you turn on the blower,that component is the problem
