Can a blower motor resistor be intermittent?
Intermittent Operation When the resister of the blower motor starts to fail, the motor operates only intermittently. The higher current can make the jump across the resistor contacts that are going bad and get the blower motor to engage.
How do you test a blower motor resistor?
Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.
What causes a blower motor resistor to go out?
In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.
What causes a heater fan to fail on a modus?
There are two common causes of a heater blower fan problem in the Modus without aircon: A. Faulty Heater Resistor (Otherwise known as the Heater Blower Resistor, Resistor Pack, Heater Rheostat or Blower Motor Resistor, Part No. 7701209803 ) Usually, it is the thermal fuse on it that fails.

Why are room heaters not good for You?
We give you four reasons why heaters are not good for you. While air conditioners remain switched off during winters, room heaters are used extensively to beat the chill. Being an easy, inexpensive and convenient way to keep warm, it isn’t a healthy way of living when it is cold.
Can a burnt heater blower cause a fire?
A burnt connector like this will cause a dead or intermittent heater blower, and replacing it will almost certainly restore the heater blower to normal. If left like this, the fault can progress until a fire is the result, so be warned. You can replace just this, or the complete Heater Resistor.

What are the signs of a bad heater motor?
Common signs include the car’s heater not working or getting stuck on a certain speed, or something getting jammed in the blower motor. 1. Blower motor stuck on one speed 2. Blower motor does not work on certain settings 3. No air from the vehicle’s vents Average rating from 130,908 customers who received a Vehicle Engine Cooling Inspection.
What happens if a heater blower has no power?
A blower motor without power will not be able to produce any air pressure, and as a result the heating and air conditioning system will be left with no air coming from the vents.
Why does my AC blower motor work intermittently?
Intermittent electrical problems can make you feel like your a blind man trying to catch a stray dog. You can’t post conmments that contain an email address.
