How to Test a Blower Motor Resistor
May 05, · Since you said the blow motor works when you ground the resistor, I would check ground G It's located on the righthand side of the engine compartment, attached to the right quarter panel. According to the diagram I have, it looks like that's also the ground for the HVAC control module, which might be why the unit intermittently goes blank. May 29, · SYMPTOMS OF A BAD BLOWER FAN MOTOR RESISTORIn this video we will explain the symptoms of a bad blower motor resistor. If you have faulty blower motor resisto.
One of the components of that system is the heater blower motor. The blower motor serves as the main electric motor that is responsible for blowing air through the vents. It is usually controlled by the blower motor resistor and switch, and can operate at several different speeds what is a carver at boston market help regulate cabin temperatures. When the heater blower motor fails, the vehicle can be left without a properly functioning heating and air conditioning system, which apart from compromising comfort, can also disable useful functions such as the window defogger.
Usually a bad or failing heater blower motor will produce a few symptoms that can alert the driver of a potential issue. If when the air or heat is turned on the vents blower noticeably less, or weaker air, that may be a sign that the heater blower motor is starting to wear out. A worn or weakened blower motor may not be able to provide adequate airflow to properly regulate the cabin temperature, and may also be approaching the end of its service life.
Another symptom of a bad or failing heater blower motor is a motor that only functions at certain speeds. Most blower motors are designed to operate at different speeds in order to be able to regulate different cabin temperatures efficiently. This can also be caused by a failed blower motor resistor or switchso having the vehicle properly diagnosed is highly recommended. No air flow from the vents when the heater or air conditioning is activated is another symptom of a bad blower motor.
If the heater blower motor burns out or short circuits, it will not function, and therefore will not be able to produce any airflow for the system. The blower motor will usually have to be replaced in order to restore proper operation to the system. The most popular service booked by readers of this article is Vehicle Engine Cooling Inspection.

Apr 23, · WHAT ARE THE SYMPTOMS OF A BAD BLOWER MOTOR RESISTOR ON DODGE JEEP CHRYSLERIf you have a Chrysler, Dodge, or Jeep and your blower fan does not work as it sho. Jul 17, · Worn blower motor causes repeat blower motor resistor failure. However, other factors can cause the blower motor resistor to fail prematurely. For example. as a blower motor ages and wears, it can draw more current—more current than the blower motor resistor was designed to handle. In that case, the blower motor resistor will fail repeatedly. Jan 08, · If when the air or heat is turned on the vents blower noticeably less, or weaker air, that may be a sign that the heater blower motor is starting to wear out. A worn or weakened blower motor may not be able to provide adequate airflow to properly regulate the cabin temperature, and may also be approaching the end of its service life.
The resistor of the blower motor is responsible for transferring the electrical current that's required to move air through the vents of vehicle. Blower motor resistors can wear out; the blower motor no longer works correctly if this occurs.
There are several symptoms that appear when the resistor of the blower motor is going bad. Recognizing these symptoms and replacing the resistor returns the airflow through the car to the proper levels. When the resister of the blower motor starts to fail, the motor operates only intermittently. This often presents itself as the blower fan not kicking on until the engine is producing a certain level of electric current.
The higher current can make the jump across the resistor contacts that are going bad and get the blower motor to engage. The blower motor could stop working again on longer roadtrips when the car is at a cruising speed and the electrical current of the motor drops again.
The lower settings of the blower motor require less electrical current to engage. But when the resistor of the blower motor is failing, it creates a larger gap between the connectors. This gap may be too far for the electric current to travel across. When this happens, the lower settings of the blower motor aren't able to function.
The top setting of the blower motor may still be operational. Reduced airflow is when the blower motor is trying to move air through the vents but the resistor isn't sending enough power to move the air with much pressure. The blower motor resistor is receiving power but not the full force.
Reduced air movement can occur at all of the different speed settings of the motor blower. Depending on how much resistor is still functioning, the reduced airflow could be an intermittent problem.
