BLOWER MOTOR
REMOVAL
(1) If the vehicle is equipped with air conditioning,
recover the refrigerant from the refrigerant system.
See Refrigerant Recovery in this group for the proce-
dures.
(2) Disconnect and isolate the battery negative
cable.
(3) If the vehicle is equipped with air conditioning,
the accumulator must be relocated in order to service
the blower motor. This is done by loosening the accu-
mulator retaining band screw and disconnecting the
accumulator inlet tube from the evaporator outlet
tube. The accumulator can then be moved far enough
to access and remove the blower motor. See Accumu-
lator in this group for the procedures.
(4) Unplug the blower motor wire harness connec-
tor (Fig. 16).
(5) Remove the three screws that secure the
blower motor and wheel assembly to the heater-A/C
housing.
(6) Rotate and tilt the blower motor unit as needed
for clearance to remove the blower motor and wheel
from the heater-A/C housing.
INSTALLATION
(1) Align and install the blower motor and wheel
assembly into the heater-A/C housing.
(2) Install and tighten the three screws that secure
the blower motor and wheel assembly to the heater-
A/C housing. Tighten the mounting screws to 2.2
N·m (20 in. lbs.).
(3) Plug in the blower motor wire harness connec-
tor.
(4) If the vehicle is equipped with air conditioning,
connect the accumulator inlet tube to the evaporator
outlet tube and tighten the accumulator retaining
band screw. See Accumulator in this group for the
