Test the voltages coming ot the fan motor, if they are ok you will need to replace the fan.

    If the AC works only on 1 position, you need to replace the blower module resistor that controls the fan speed. Ask to your car dealer, if you mention the problem they should be able to indicate you the right part straight away.
    If you get the replacement resistor, and you want to do it yourself, ask the dealer a photocopy of the schematics, so that you can replace the part.

2002 ford focus fan knob not working at all 1 2 3 or 4 to turn heat on, although you can feel minimal heat coming from the vents.


Probably a blown fuse? Does the AC light come on when it's turned to MAX setting and the fan is on 1 thru 4 speed?It should.

2005 chevy equinox do my radiator and condensor


Hello: You may have a cooling fan(s) problem. Start the truck, turn the a/c on max, both fan and a/c control. Open hood the cooling fan(s) should be running. If not then you will need hands on trouble shooting. It could be fan(s) motor(s), relays, relay control, ie PCM, wiring, fuse etc. Systematic hands 0n trouble shooting will be needed with a upscale scan tool.

2005 chevy colorade check engine light comes on in warm weather and goes off in cool or cold weather.this has happen several times


Has this problem come shortly after refuelling? Do you live in a humid climate? 9 times out of 10 this is a result of the gas cap. Failing that, can you get your hands on a OBD 2 tool or go to your dealer and have them scan the truck. The Check Engine Light throws a code and the OBD2 tool reads that code. The code points to the problem.

The a/c and heater fan speed switch with the 1,2,3, and 4 modes are not working. first 1 and 2 didnt work now only 4 works. so if i want my a/c on the only option i have is 4. the car is a 2002 chevy...


most probably the heater resistor is bad , its just beside the blower motor, with a harness of 4 to 6 wires connected to it , usually blown because the blower motor is drawing too much power

2005 Chevy Avalanche - my heater contol turns the fan off when I put it on #5......works fine on 1, 2, 3, and 4, but as soon as I turn it to 5 ....it stops.....


Motor switch has gone out, most likely due to high load on level 5. Replace switch and I suggest lubricating blower motor bearing to help take the strain on the system.

Heater and Air conditioner does not go on. COuld


Could be a fuse, but try it all the way on high first. If it works on high only, it's most likely the resistor in the fan control. Hapened to mine a couple of times and Chevy charged me about $150 to fix it.
