on the passenger side floorboard you will see the black plastic duct work for the heater. you will also see two screws right about the center of it. this is where the resitors are for the speed control of your fan. it takes about ten minutes to change.

How do you replace the blower fan resistor on a 2003 buick rendezvous?
where is the switch resistor on 2003 buick
Heater fan switch works only on the highest setting?
The blower motor speed resistor is burned out. You can replace only the resistor but the resistor probably burned out because the blower motor is going bad. If you want to fix it for good, replace both the blower motor and blower motor speed resistor.
If the blower stopped working my 2001 Kia Spectra could this be the motor blower resistor or should I replace the blower motor?
Check to see if you are getting power to blower motor - if so replace blower motor If not check fuse, switch, resistor pack.
Only high-speed on fan was working now it doesn't is it the switch or the blower and how can you tell which one it is?
It is most likely a bad blower motor resistor. Replace the resistor. If the problem continues, it could be the switch.
1998 dodge stratus you replaced the blower motor resistor and your blower motor still works on high only?
replace the blower motor switch
Why is the fan blower not running in switch positions 1 2 and 3 on your Mazda 626?
Defective Blower Motor Resistor Pack. Replace it.
Why does the blower switch work on all but high for 1997 GMC Safari?
You need to replace the blower motor resistor. I've been there done that.
Why does your heater only blow on high?
Most likely your blower motor resistor is bad. I replaced the resistor and the blower motor fan and it ended up being the speed control switch (alot easier to replace than the resisitor). Both the resistor and switch are around $19.
How do you tell if Chevy fan blower resistor is bad or the selector switch?
Examine the back of the switch for loose or melted connections. Then examine the resistor for burned spots. In most cases a burned resistor is the result of a failing blower motor. So if a new resistor burns out in a short time, replace the motor also.
How do you test a resister in a blower?
To test the blower motor resistor, unplug the resistor connector. Each blower motor switch input terminal on the resistor must have continuity to the resistor output terminal, which is connected to the circuit going to the blower motor. If the blower motor resistor continuity does not check OK, replace the faulty resistor.You need a multimeter to test the resistor block and there should be continuity between all terminals.
Why your 1997 marquis not working on low after you change resistor?
Assuming you are asking about the HVAC blower motor, check the condition of the switch and the electrical connection at the switch. And, if the original resistor was burned out the cause is usually because of the blower motor drawing too much current. If so, replace the blower motor or you will burn out another resistor soon.

Replace the blower motor resistor.
