Here's a cut and paste from the 2002 service manual. --Geoff
BLOWER MOTOR DESCRIPTION The blower motor and blower wheel are located in the passenger side end of the HVAC housing, below the glove box module. The blower motor controls the velocity of the air flowing through the HVAC housing by spinning a squirrel cage-type blower wheel within the housing at the selected speed. The blower motor and blower wheel can be serviced from the passenger compartment side of the housing. OPERATION The blower motor will only operate when the igni- tion switch is in the On position, and the a/c heater mode control switch is in any position, except off. The blower motor circuit is protected by a fuse in the junction block. On models with the standard manual temperature control system, the blower motor speed is controlled by regulating the battery feed through the blower motor switch and the blower motor resis- tor. On models with Automatic Temperature Control (ATC) system, the blower motor speed is controlled by using a linear blower controller with a pulse width modulation input. The blower motor power module adjusts the battery feed voltage to the blower motor, based upon an input from the blower motor switch, through the ATC control module. Pulse width modulation of blower power allows the blower to operate at any speed from stationary, to full speed. The blower motor and blower motor wheel cannot be repaired, and if faulty or damaged, they must be replaced. The blower motor and blower wheel are not serviced separately and must be replaced as an assembly. REMOVAL WARNING: ON VEHICLES EQUIPPED WITH AIR- BAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISO- LATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYS- TEM CAPACITOR TO DISCHARGE BEFORE PER- FORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRE- CAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. (1) Open the hood and disconnect the negative bat- tery cable remote terminal from the remote battery post(Refer to 8 - ELECTRICAL/BATTERY SYSTEM/ CABLES - REMOVAL). (2) Remove the lower right under panel duct. (3) Remove the blower motor connector from the blower motor resistor block/power module. (4) Squeeze the blower motor wiring grommet and push the grommet through the blower motor housing cover. (5) Remove the blower motor housing cover. (6) Remove the blower motor retaining screws. (7) Lower the blower motor from housing. INSTALLATION (1) Install the blower motor in the HVAC housing and tighten the mounting screws to 2.2 N·m (20 in. lbs.). (2) Install the blower motor housing cover. (3) Position the blower motor wiring grommet in the blower motor housing cover. (4) Connect the blower motor harness connector to the blower motor resistor block/power module. (5) Install the lower right under panel duct. (6) Connect the negative battery cable remote termi- nal to the remote battery post(Refer to 8 - ELECTRI- CAL/BATTERY SYSTEM/CABLES - INSTALLATION).
