BLOWER MOTOR RESISTOR
REMOVAL
1) Disconnect negative (–) cable (2) at battery (1).
2) Disable air bag system, if equipped. Refer to DISABLING AIR
BAG SYSTEM in Section 10B.
3) Open glove box (1), then remove screw (2).
4) Remove glove box.
5) Disconnect blower motor resistor (1) at coupler.
6) Remove heater blower resistor (1) by removing its fastening
screw (2).
INSPECTION
Measure each terminal-to-terminal resistance on resistor.
Resistance H-LO: Approx. 2.0
H-M1: Approx. 1.0
H-M2: Approx. 0.4
If measured resistance is incorrect, replace heater blower resistor.
INSTALLATION
1) Install heater blower resistor with screws.
2) Enable air bag system, if equipped. Refer to ENABLING AIR
BAG SYSTEM in Section 10B.
