Heater and A/C Blower Motor Replacement

Mobile Heater and A/C Blower Motor Replacement at Your Home or Office

When your blower motor resistor malfunctions, your fan might operate at high speeds but fail to function properly at lower ones. Ignoring this issue can lead to overheating and potential damage to your A/C system. Let us help by installing a new air conditioner blower motor, restoring smooth airflow from your fan. Blower motor resistor problems are prevalent in many vehicles. The most common sign of a faulty blower motor resistor is when the heater fan operates only at the highest speed setting and fails to work at lower speeds. In some cases, a malfunctioning blower motor resistor can cause the heater fan to cease functioning altogether.

What is a Heater and A/C Blower Motor?

A blower motor, also known as an air conditioner (A/C) blower motor, heater blower motor, or heater fan motor, is a vital component of your vehicle’s heating, ventilation, and air conditioning (HVAC) system. Controlled by the knobs or buttons on the climate control unit, it is responsible for circulating cold or warm air from your vehicle’s A/C and heating system through the interior vents, distributing it throughout the cabin. Even if a vehicle lacks an air conditioning system, it will still have a blower motor assembly to circulate outside air inside the cabin, in addition to providing heat.

How is Heater and A/C Blower Motor Replacement Done?

If the blower motor fails to function at all, it must be tested first by measuring the voltage at the blower motor connector when activated. If voltage is present but the motor fails to run, it indicates a faulty or jammed motor. Typically located underneath the glove compartment, accessing the motor may require removing the glove box. The motor can usually be removed by loosening screws or bolts and disconnecting the motor harness. Reinstallation involves inserting the blower motor, reconnecting the wiring harness, and repositioning the glove box if necessary.

Recommendations
