The blower motor in a Pontiac Grand Am is a small motor that spreads the air that comes through the car's vents. The motor turns a small basket wheel inside your ventilation system. If the blower motor goes out, no air will circulate through the vents. The blower motor is located beneath the glove box in Grand Ams. It is accessible by removing the trip panel.
Open your Grand Am's hood and remove the negative battery cable.
Slide your passenger seat back as far as it will go, allowing you room to work. Using a screwdriver, gently pry off the trim panel just below your glove compartment. In some vehicles, the blower motor is accessible through the glove box. Accessing the motor via the panel under the glove box is slightly easier and gives you additional room to work.
Press the two locking tabs on the wiring harness. This harness is plugged into the existing blower motor. As you press the tabs in, pull back on the wiring harness.
Using a screwdriver, remove the Grand Am's three retaining bolts that mount the existing blower. Once you remove them, pull the old blower motor out. Using the mounting holes as a guide, match up the new motor's holes with the mounting holes. Tighten the motor down with your wrench.
Plug the wiring harness into your Grand Am's new blower motor.
Reconnect the negative battery cable.
Turn on your car; ensure the new blower is working.
