If you are talking about the inside heater a/c blower motor, it may be starting to go. You also might want to check the blower motor relay in the black junction box under the hood, usually near the battery. If this relay is cutting out, it may be bad or may be cutting out becuase the fan motor is drawing too much current due to wear.

I would check to see if there is a short on the fan controller switch and the motor. sounds like a crossed wire, especially if it's ignoring your speed selection and running when the key is out. could be near the fuse box under the dash. the cig lighter circuit is live all the time as well as a couple others, it maybe crossing with it. I would pull the fuse panels assem down and check for crosses and shorts.

02 kia spectra fan/blower not working, all fuses relays good but no power to either? ??


No power to heater blower fuse? this isn't separately fused to my knowing ,if there wasn't any power to this fuse other devices wouldn't work as well , as fuse under hood supplies power to many things , what ive found many many times to satisfy this complaint is that yes there is power to underdash fan , but its rusted up and cant turn , rust occurs when ac drain backs up and water has nowhere to run ,except to motor , then rust starts !!

Why blower fan won't turn off after i turn off ac/heater


You relay switch is stuck on. Replace it. Second thing to check is the fan switch may need to be replaced. If you turn off your engine and then back on does the heater fan go on even when it is turned off at the switch?

05 nissan maxima making a loud noise when the heater or the AC turns on but the heater and AC works need help


-Depend on what sound like...? It could be loose fan, some object hang in to the fan, or dry leave or may be some thing stuck inside the fan's housing.
-You can open from the inside and check. If find some thing, remove and turn on to find out still any noise before closed.

Good Luck

Fan does not blow in 2002 chrysler sebring


If the heater fan only runs turned on full, it's likely the resistor pack that controls the speed. They usually can't be bought or put in my normal folks.

Temp gauge often reads too hot, engine normal.


It sounds like your cooling fans are not comming on by themselves, but when you turn on the ac it forces them to turn on. Make sure relay is good, then replace coolant temp sensor, this may have failed no telling pcm to turn on cooling fans. Thanks

Radiator fan will not run but motor is good


follow the wires coming off the fan they will lead you to the relay from that the relay will run to the temp sensor which trips the relay for the fan
