Question about 2006 Chevrolet Trailblazer Ext

1 Answer

Just today, my a/c fan blower motor quit-it "blows" cool air at high speeds, so do not think it is the compressor- also, rear air & blower work fine- I checked (I think) all of the fuses and they seemed okay. 40,000 miles on car and no problems otherwise to date. Any suggestions? Thanks. John Murphy.

    I have the exact same problem in my '03 Trailblazer. AC emits cool air but does not blow while the rear fans blow just fine. I also checked the fuses and they seemed fine. I have Climate Control on mine and I believe it to be a sensor that is malfunctioning - not sensing the temp in vehicle that sets off the blowers.

It is the blower motor resistor. I had the same problem on my 05 ext and now it just happened on my 06 ext. It is located behind the glove box, very easy to change.

Weak blower motor


Check good voltage and ground for blower motor. Actuators under the dash may be restricting air flow? High speed doesn't usually use a resister.
Check for hvac trouble codes, in my part of the country, some of the national brand autostores will check codes for free, if there are any.
If you think problem with blower motor, itself, replace it. Sometimes, you can remove blower motor, use jumper wires for voltage and ground, using inline fuse, come off the battery, see if it blows like you think it should?

The a/c on my 2010 Mercury Milan quits blowing after about 2 hours of driving. Any ideas?


Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.

Ac fan speed


Replace the blower motor resister,this is the speeds for the blower motor,it is located very near the blower motor,and is mounted on the blower box,and it actually goes inside the box,to keep it cool.The reason for it`s failure is the blower motor,even though the blower motor sounds,and runs good,it is drawing too many amps.If this was at all helpful,please rate,thank you.

The ac quit working...no fan, no air. The 30amp


check the ac blower transistor under passenger side of dash behind the blower motor. on my 2003 compressor would not cut on , front blower only operated on high an blew hot air, rear blew on all speed but only hot air. $58.00 at dealer plus tax. 15 minute fix. there is a video on youtube that documents the process. just fixed today

I have 2001 Volvo S80 and the heater and AC comes on for a minute or two and then shuts off. The dealer said it was the blower mower burned out. How can that be if it works now and then?


Assuming that the dealer is correct and isolated the problem down to the blow motor...
it IS possible for the motor to work intermittently due to heat buildup. Malfunctions due to heat will call the motor to run fine for a bit, and then quit when the motor reaches a high enough temperature to cause a malfunction. It would then quit working until it cooled back down, and repeat the process.

Whether is it just dead, or it is intermittently dead, for all intensive purposes, the motor is no longer usable and needs to be replaced with a new unit.

No high speed on fan for heat and air


Replace your high speed cooling fan relay with a known working relay (rear window defrost for instance) and see if the fans turn on while the air is on high. If so, you need a new relay. You can also look into the fuse that protects the relay circut.

A/c doesn't blow unless high speed


Its your blower motor. Check the strip fuse (30 amp) outside the fuse box in a tootsie roll sized clip case by the strut mounts. In between the fuse box and strut mount. If not you may need a regulator or new blower motor.

Car heat blower is not blowing heat/air into the care


it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.
