had this problem a few years back. i took of the glove compartment and under in the area by the fan there was a card. it was bad. look into it. should solve your problem
the resistor has melted the variable settings. Replace resistor under passenger dash.
The blower resistor has failed. Located behind glove box door.
Assuming you're talking about the blower motor, because the blower motor resistor is faulty, and needs to be replaced. On the high setting, it doesn't go through the resistor - on the other settings, it does.
The blower motor resistor pack is defective. Replace it.
If you mean the fan works on high only it's the blower motor resistor.
Bad blower resistor? Bad switch?
: My 2002 focus blower fan worked at the highest setting only and not 1,2 and 3. I fixed it by replacing the blue resistor pack held down by 1 screw behind the glove box next to the blower motor. : At first I checked the power supply to the blower motor connector. I was getting power only at setting 4 and none at other settings. : Fan blower electrical diagram showed that the only connection to the fan blower is the power supply, resistor pack and front panel switch.
Defective blower motor. Although I do not know if this is the problem, I have seen this on other vehicles. Check into the blower motor resistor. RockAuto.com has them with great pictures so you know exactly what you are looking for. They are generally located close to the blower under the dash. Very easy fix just a couple of screws. Cheaper and easier than replacing the blower motor.
I think you have problem with the blower resistor. Please follow the procedure to check. * remove the connector to the blower motor. * use voltmeter to check the voltage. * connect one probe to the ground and the other probe to the 3.0R/w of the motor supply. * turn on the the blower motor with dial, you should read supply voltage, 12Vdc. * if you have positive voltage at the 3.0R/w then you should check the blower resistor and blower switch. blower switch supplies battery negative to the blower motor through the blower resistor. if you need further help please just let me know.
there is a resistor that controls the speed and should be near the blower motor its called blower motor resistor
ITS IN THE FUSE BOX. THERES TWO OF THEM, ONE IS LABELED TOP BLOWER AND THE OTHER LOWER BLOWER.
The blower resistor has probably failed. The connecter also likes to fail. They are located under the hood on the large black plastic housing on the passenger side. There are 4 wires in the connecter.
