Installation of the blower motor for the Nissan Altima involves removing the glove compartment and other components of the car. While this sounds like a lot of extra work, the glove compartment comes out easily and the blower unit is located directly behind it. The blower motor is located within the blower unit and is a little different than you may imagine.
Align the eight locking tabs on the blower motor with the slots on the blower housing and snap the two pieces together. The assembly can now be installed in the car.
Position the blower unit in the car and install the two bolts at the top of the unit along with the screw near the bottom of the blower unit. Tighten the bolts with a wrench or socket and the screw with a Phillips-head screwdriver.
Install the electrical connector for the blower motor, intake door motor and fan control. The connector will snap into place on the blower housing.
Install the glove compartment into the dash board by sliding it into place and installing the eight retaining screws. Tighten the screws with a Phillips-head screwdriver.
Test the motor by turning the blower switch on and cycling it through the speeds. The blower should speed up and slow down as you work through the positions on it.
