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.
Why does my heater on my Pontiac Grand Am Not turn on?
Now the heater fan runs on all speeds. So if you are having this problem of the heater fan will not turn on , in a Pontiac Grand Am or similar GM car hope this helps.If the heater fan will only run on hi it is most likely the fan motor resistor. Loading…
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.
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 to change a heater relay on a Pontiac Grand Prix?
Sit in the passenger seat of your Grand Prix with the car turned off and the ignition key removed. Open the glove compartment and locate the bin on the side of the glove box. Pull the cover from the bin to expose the fuse panel inside the glove compartment.
How do you change a blower fuse on a Grand Prix?
The blower motor depends on a properly functioning 15-amp fuse to regulate the power flow that controls the blower motor speed. Buy a variety of fuses to keep on hand, and replace a blown fuse yourself in minutes. Sit in the passenger seat of your Grand Prix with the car turned off and the ignition key removed.
Where is the fuse on a Pontiac Grand Prix?
The Pontiac Grand Prix has a blower motor that is regulated with a fuse located in the fuse panel inside the glove box. If the blower motor in your Grand Prix is malfunctioning, you may have blown a fuse.
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.
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.

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.
