How to change the blower resistor pack on a 2002 Pontiac Grand Prix?

Gently pull down and back on the blower resistor pack, rocking gently side to side to slide the pack off of the screw that you loosened. Once it pops free, the blower resistor pack will pull straight down and out for complete removal from your 2002 Grand Prix. If you inspect it, it is usually obvious where the resistor has burned and failed.

How do you remove a 2002 Grand Prix?

Loosen this hidden screw approximately two turns without removing it. Gently pull down and back on the blower resistor pack, rocking gently side to side to slide the pack off of the screw that you loosened. Once it pops free, the blower resistor pack will pull straight down and out for complete removal from your 2002 Grand Prix.

What causes a blower resistor pack to fail?

Blower resistor packs cause most of the failures. Rarely does the blower motor itself fail. The blower resistor pack drops the voltage to the blower motor, reducing the speed of the fan motor at lower speed settings. Less power equals less airflow. Restricting the voltage creates heat in the resistor pack, and over time, the resistor burns.

Where is the sound damper on a 2002 Pontiac Grand Prix?

Open the passenger door. Get down on your knees, and look up above where the passenger feet go, directly under the glove box on your 2002 Grand Prix. There is a cardboard reinforced felt sound damper held in by plastic retainers. Gently pry the plastic retainer clips, being careful to not damage them. Remove the sound damper.

How do you replace a blower motor resistor?

Remove the screws that secure the blower motor resistor to the housing… and put them someplace safe. At this point, you can remove the resistor from the housing. Take your new resistor… put it in position… and install it using the screws that held the old resistor in place.

Where is the resistor on a blower fan?

Some common locations are near the blower fan motor, under or behind the dashboard, around the passenger footwell etc. Once the resistor is located and detached, it is often possible to say whether the resistor has burned out or not judging by the physical appearance only.

How to troubleshoot the air conditioning in a Pontiac Grand Prix?

See if the problem is as simple as a blown fuse. It is probably a blown fuse if the temperature controls on the dashboard seem to work correctly but have no effect on the air. Find the fuse box in a Pontiac Grand Prix inside the glove box.

What happens when you change the blower resistor pack?

The blower resistor pack drops the voltage to the blower motor, reducing the speed of the fan motor at lower speed settings. Less power equals less airflow. Restricting the voltage creates heat in the resistor pack, and over time, the resistor burns.

Why did my Pontiac Grand Prix blower pack fail?

In the heat of summer, or the frigid depths of winter, blower motor failures frustrate numerous owners of 2002 Pontiac Grand Prixs. Blower resistor packs cause most of the failures. Rarely does the blower motor itself fail. The blower resistor pack drops the voltage to the blower motor, reducing the speed of the fan motor at lower speed settings.

How to change the blower resistor pack on a 2002 Pontiac?

Cut down several inches to make a flap of the sound insulation. Pull the flap down to provide more access to remove the blower resistor pack. Pull the gray safety retaining clip out of the connector to the blower motor resistor. Once this is free, unplug the blower motor resistor pack connector.

How can I tell if my blower motor resistor is faulty?

Another symptom of a faulty blower motor resistor is no air from the vehicle’s vents at all. Power to the blower motor is fed through the blower motor resistor, so if it fails or has any issues power can be cut off to the motor.

What does the blower motor resistor do in a car?

The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor.
