Is there a reset button on a furnace blower motor?
All furnaces are equipped with a reset button. They are generally red or yellow and are located inside the blower compartment. The reset button is a safety feature that will shut down the furnace when a problem is detected, often a hot or overheating furnace, before it trips the circuit breaker.
What to do when your heater fan stops working?
Fuse Good Relay (fan speed under hood) on firewall replaced Still no power getting to blower motor (purple wire) Mechanic found the harness plugging into the fan switch in the dash had melted. Unplug and take a look at yours. A.C. and heat blower now work. I was surprised the meltdown in harness dident blow any fuses 3 people found this helpful.
Why does my AC blower motor not work?
The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all. This may also cause the blower motor to work intermittently.
Why is the resistor not working on my blower?
Hi There, The resistor is what controls the speed of the blower motor, not the relay. The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all.
Why does my Chevy S-10 heater fan stop working?
If this system is wired as a simple circuit and has a ground side resistor to provide speed changes, that’s how it reduces the current flow. when using “hi blower” the resistance would be in the melted connector you found. If this system is controlled by a more complex climate control it may be scanned or self tested.

Why is my blower motor resistor not working?
CLICK HERE TO RESET YOUR PASSWORD! Help! Fan quit working on all 4 speeds. AC light & recirc light still light up and AC compressor clutch engages when turning fan on in AC mode, but not getting the fan to work. I replaced the blower motor resistor and the control unit with new parts from rockauto (ACDelco).

Why does my air conditioner blower not work?
We’ve got a little extra weirdness going on in this one ’92 s10. The blower will work, but only after tapping on the resistor/relay/fan speed switch. Changing the fan speed or turning the blower on or off will cause it to fail again until you give the relay another good tap or two.
