    I had this problem about 3 years ago, Under warrany, the dealer replaced the resistors underneath the glove box. Where your passangers put their feet. There are 3 or 4 resistors soldered to a plastic plate that plug in. They allow the fan to operate at different speeds., mine only worked on high. You can go to the dealer and get the exact replacement set and install it your self for a lot less. When I did it, I read them out with a fluke, but since it was a warranty item I figured I'd let the dealer fix it. Hope it helps.

fords are notorius for faulty fan switches, you will need to get a new one, but it will probably fail in a year or two.

SOURCE: heater (and a/c) blower motor runs only at the two highest speeds

I had the same exact symptom (02 Prizm LSI)..Order yourself a Blower Motor Resistor (I clicked on it---scroll up on this same screen that you are reading--- AC Delco part, $25.79). When the part arrives, look at it, and then look behind and to the left of your glove box door, YOU WILL SEE IT RIGHT AWAY. 2 screws, takes about 10 minutes to change. Its been nice to get all 4 speeds back! Good luck.

We have a 2006 Jeep Liberty. Our heater/ac would only work on 4 (highest setting) for the longest time. Now it only will work when it seemingly wants to.Replaced blower motor resistor with no change


Sounds like the blower motor speed control switch may be defective or you have burned wiring or connectors, pull the blower switch out of the dash and examine it for signs of overheating and a burnt smell, check the connector at the blower motor as well for same things, repair as needed, also I would replace the blower motor as well.

My blower only works 1 through 4 and will not work on the highest position number 5


{: ) Check out the J-case fuse (square) labeled BLWR 40amps at the underhood fuseblock. This fuse is the source of power to the blower motor when position 5(max speed) is selected. If this fuse is tested to be okay, you need to access for the blower resistor connectors. Turn ignition on, and set blower to max speed (#5). Probe on the blower resistor terminal (orange wire) and you should get 12volts, also probe the terminal (red wire) which came from the 40amp fuse. 12v should be present on these two terminals at the blower resistor when at max blower speed. Particularly on the orange wire, if you don't get 12volts when at #5 position, it 's probable that the blower speed control switch is faulty. But if you did got 12volts during the procedure, then you should replace the blower motor resistor. Goodluck.

05 GMC sierra heater blower stopped working. It used to work on setting 1-4 but lost 4 a couple weeks ago and now none of them work. Is this a bad blower , resistor or both?


The resistor is most likely bad but should still work on the highest setting.Would check pigtails to the resistor and to the blower motor for burnt or discolored wiring.You can try tapping the blower motor and wiggling the wiring harness too see if it will work on the highest setting. It is possible that the blower motor is bad as well typically when you lose the speed selection it is the resistor but you should always have high speed.

Ford fusion 2007, blown blower fuse, replaced fuse, works at highest speed only (highest of 4) the other three setings don't work.


hte blower resistor is shot, near the blower motor, have the blower motor checked my guess is that it requiring too much power to run, hence the blown fuse

Fan switch only works on the two highest settings


the various speeds are controlled through resisters (spring-like in apperance) one of different value for each speed, none for highest speed as the power gets to the blower uninpeeded . the resistor pack should be located on the center of the firewall, held by 2 screws. thats under the hood. where the engine bay ends....

Vent fan only works when set to 4


Hi.....
On your Vehicle the problem for the FAN speed is NOT the FAN switch.
99.9 % of this problem on cars is the BLOWER MOTOR RESISTOR.
The blower motor resistor give the speed to the Fan.
But on High speed the switch make a By pass of the switch using a Relay for the high speed.
The Blower motor resistor, is located Beside of the Blower motor On the passanger compartment.

If you replace the blower motor resistor you have 99.9% of this will solve your problem.

I'm a Mechanic.

I hope this help on your problem.
Thank you for use fixya...

Faulty Heater Fan


I would check the blower motor resistor. The resistor slows the current going to the blower motor to make the fan run slower for the first three speeds.The high speed runs of full battery voltage.I hope this helps.
