How do I know if it's the blower motor or the resistor?

Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.

Can a bad blower motor cause no heat?

Problems with Your Blower Motor or Blower Motor Resistor Without it, there's no circulation of air—hot, cold, or otherwise. The blower motor resistor is the part that controls the fan speed of the blower motor. Both of these components can fail, resulting in the heating system simply not working.

Why do I have to hit my blower motor to work?

Blower motor only start working after i hit a bump. In most cases that is a sign of worn down blower motor brushes not making a good contact. In some cases the blower motor/resistor pigtail could cause erratic operation of the blower motor too.

The resistor is at the bottom of the HVAC housing or just behind the glove compartment.Where is a blower motor resistor located? The heater blower motor resistor is often found beneath the dashboard. It is located in the heater and air conditioning compar...


  • Where is the blower located in the AC unit?
  • The air conditioner fan is located in the condenser unit (the portion of the AC that is parked outside your home). Therefore, to determine whether or not this part is working, you'll have to walk outside and look at the fan through the vents of the condenser unit.Is the blower motor on the inside or the outside? Unlike the condenser fan motor, the blower motor is located indoors. It's the componen...


  • How do I know if I have blower motor or resistor?
