Check the speed module or resistors for the fan as it appears that the problem is there.

Check the ground, the resistors are accully resisnting the Negitive Current.

SOURCE: Heater fan only works on high speed 4.

sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.

SOURCE: 1992 cadillac deville - hvac blower motor does not shut off.

replace the relay , when a relay sticks like that , a good test is to slap it with something like the handle of a screw driver , see if it un-sticks , its not a fix , just a test . cheers'

SOURCE: Lincoln 2000 town car Blower doesn't work at HI-MED-LOW speeds...

it is called blower motor resistor , should be close to blower motor , you will see a plug type connector with two screws , remove the screws and there should be a resistor inside the cover for the motor, swap with new and reassemble

You have clean the blower unit , may be its dirty then . and then check the blower resistor unit for malfunction.

II have a 2010 chev malibu the heat and cooling fan does not work


Check for power at the fan resistor wire to the resistor, if power. change the resistor block itself. it controls fan speeds. Most resistors are beside the blower fan, below glove box. You may have to remove a panel to get to the fan resistor. check all fuses first! Even under hood fuse box.

I have a 1998 olds 88 And. The blower motor motor isn't working where is the relay for the blower motor exactly


I think under the hood in a fuse box.I would check the blower motor resistors connection afterwards.Turn ignition and fan switches on then wiggle the pigtail going to the resistor.Its located in the heat duct on the passenger side near the floor.These resistors are known for getting hot and melting the pigtail causing it to loose connection.

Question:If the 30 A. fuse on a 2002 focus dash blower motor is good,and the thermal resistor is replaced, then it must be a faulty speed switch?


Don't know where you got your info . The heater blower motor electrical B+ power comes from Fuse F 64 a 40 amp fuse . This goes right to the blower motor on the green with orange stripe wire , The black with red stripe wire goes to the switch for high speed . There is Splice 24 that ties into the black with red stripe wire. The splice 24 turns into a black with orange stripe wire . An this wire goes to the blower motor resistor . All the switch does is route the B+ voltage through the different resistors to ground .

Thermal resistor "usually" stops working is because of faulty fan speed switch ???? Totally not true , resistor assemblies fail because of the heat associated with dropping voltage across the resistors , That is why they put the resistor assembly in the air box . Air blows over to cool the resistors . The switch is nothing more then a way to direct different speeds to ground .

Rather then listening to other people ,why not learn the right way to test electrical circuits .

Hello my name is Sean and I have a 2002 ford focus wagon with a 2.0 motor. The blower fan for the heat and air has stoped working. I have ordered a new blower fan and resistor but havent received yet. I...


the fan motor is maybe bad, disconnect it (the motor) and put in new fuse, if its ok, then the motor is bad. the resistor only handles speeds lower than HIGH. so replace the motor first, then try it, if all speeds work, then the resistor is OK.

I REMOVED THE AC FAN SWITCH FOR THE THE FAN AND WHEN I PUT IT BACK ON IT DOES NOT TURN ON ANY MORE. HOW DO I RE-INSTALL THIS TO WORK AND TURN ON FAN FOR AC AND HEATER?


Fan switch ? Blower fan or engine cooling fan ??...I presume you mean the blower fan speed control switch.

On top of the battery under the hood, is a set of Green 30Amp fuses. These burn out the holder and a/c no longer works.

If so, by pass fuse with a replacement/repair '' in line fuse'' of 30 Amps from you local parts store.

Other reason fan not working is failed fan resistor under glove box near fan housing....although this is usually low speeds not working by HI does.

If you have the non electronic a/c system, the a/c rotary switch in the panel burns out often.

Blower on the heater/AC not working on 1998 Escort, checked fuse under dash?


Ok, first off, check the fuses under the dash. If they're all good, does the blower work only on high speed? If yes, then you have a bad blower motor resistor, which is located under the hood, near the blower motor itself. If the motor doesnt work at all at any fan speed, make sure the wiring harness that plugs into the motor under the hood is clean and tightly installed. If it still doesnt operate, sometimes tapping on the blower motor housing will kick it on, but if that doesnt work, you may have to replace the blower motor. They are available aftermarket, and arent usually too expensive.

Heater wont work a fuse maybe? some how I doubt it. the rear window heater works. fan dead perhaps? no fan at all. not sure about heat.


Hi: Sounds like a possible heater resistor problem. First check to see if heater fan working, unplug heater under hood and put 12 volts to it from the battery with a wire (single black wire running to back of fan). If works then problem probably the resistor which is located on the fan housing under the hood to the right of the fan. The resistor has wires to it running from the heater fan, 2 - 7mm screws holding resistor in place, check resistor to see if any of the 3 elements are melted off, if so replace. Note: Rear window defrost has nothing to do with heater fan. Hope this helps...

fan blower resistor. Under hood near blower motor. Follow the power that goes to blower back to resistor, there should be several wires on it. That's the most LIKELY source of your problems.
