Question about Pontiac Aztek

Blower motor fan speed control switch

My fan only blows on one speed. No matter what I turn the dial to, it stay blowing at one speed. Sometimes it is on high and sometimes it is on med/low. So, I know it is not the blower motor. It is a problem with the switch. I would like to order a new one but the dealer in our rural town can only order the entire climate control dash. I need just the plug (I believe). What is this plug called and where can I order it? Do you think it will solve my problem?

It is probably the blower control module, not your temperature switch - I would try replacing that.

SOURCE: new climate control unit but when on blower not working for heat or ac

I'm assuming the problem is the blower motor isn't coming on or working. 1st, check the fuse. 2nd, remove the glove box or pull the 2 tabs that act like stops when it's open ( the glove box will open out further) and you'll see the power plug connector for the blower unit. Turn on the blower through the climate control (heat, A/C, or whatever) and wiggle the connector to see if the blower turns on. If starts working, then an easy solution is pull the connector off and gently press the prongs together or inward. Then carefully reconnect with damaging the prongs. This worked for 96 Mark VIII due to the fact the prongs were not "seating" correctly in the female connector. It's been about 2 years since I did this and the connection is still good. If wiggling the plug doesn't work, pull the plug, turn on the climate control (heat, A/C), and check for voltage to the plug. That's about all I can help with.

SOURCE: Front climate control blower only works on high speed.

Replace your blower motor resistor
Resistor located under dash on passenger side in screwed into blower housing. May be able to be repaired. Requires soldering a small piece of "unmelted solder" across where the old fusible link was. look carefully at resistor. Or else just replace. Buy new. Junkyard resistor likely to be as bad as yours.

SOURCE: Blower on heater works sometimes, sometimes it

Sounds like the blower resistor. It will either be located in the engine compartment outside the motor or inside the vehicle inside the blower motor cover. It could also as well be selector switch

AC blows cold air, fans stop blowing


I think you have a "variable speed resistor" problem, it's overheating. It's an electronic device usually located near or attached to the AC motor blower that controls the fan speed. This is a common problem with aging AC blowers with electronic controls.

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.

The mercedes benz e320 2003 A/C blower works only sometimes.


the fan must be removed and checked for binding and drag. if it gets worse, a fuse will keep blowing. if the motor spins freely, then the controls have to be diagnosed

My heat is hot but doesn't blow. Is it the resistor, motor or something else? I checked my fuses they look fine.


Clear out the dust on the dial and slide control first.
MOVE these control back and forth and sensor for broken linkage and connecting rods.
If these are able to move smoothly then turn the back and froth and monitor for the flap / defector blending valve movement.
Pass a ShopVac to clean out all the dust.
==== The resistor pack for the blower motor can fail over time.
Check loose connector on blower and resistor pack around the firewall.

Please keep me up to date on the fix via email.

The blower motor on my heater will not turn off. When I move the switch it keeps blowing regardless of the setting.


Hello you do not specified the make and model of your car regardless you will need to locate your blower motor speed switch usually located within inches from the blower motor it self some people call this switch the blower motor isolator switch as well this controls you fan speeds.Sometimes you loose one or more speeds and usually your left with one speed before it quits all together

A/c fans wont blow


If the fuse is blown for the blower then there is a short, that is not an answer, go to the blower and check to see that the blower motor connector has 12 volts to it when the blower is set to high speed on control, if it does then u need a new blower motor, if it doesn't then the control switch is defective or the blower motor speed control resistor is defective.
