connector to the damper gear motor. If these wires
have good continuity, the damper gear motor is
probably defective.
Replacing Damper Gear Motor
1. Remove the evaporator access panels as necessary
to access the damper gear motor and damper door.
2. Remove the two bolts that attach the damper door
to the damper door shaft.

3. Remove the two bolts that attach the damper door
to the damper gear motor shaft and remove
damper door.
4. Disconnect the damper gear motor harness from
the main harness.
5. Remove the three screws that attach the damper
gear motor to the evaporator blower housing and
remove the damper gear motor. These screws are
located on the inside of the evaporator blower
housing.
6. Place the new damper gear motor in position and
fasten it to the evaporator blower housing with the
three screws.
7. Reconnect the damper gear motor harness to the
main harness.
8. Place the damper door in position and fasten it to
the damper gear motor shaft with the two bolts.
9. Fasten the damper door to the damper door shaft
with the two bolts.
10. Replace the evaporator access panels that were
removed to access the damper gear motor and
damper door.
Condenser and Evaporator Fan
Location
When mounting the condenser or evaporator fan and
hub assembly on the fanshaft, the blowers and inlet
orifices must be properly aligned for proper air flow
and to prevent damage to the blower.
Condenser Inlet Orifice Alignment
1. Loosen the condenser inlet orifice on the condenser
coil bulkhead.
2. Center the inlet orifice in the condenser blower and
tighten the inlet orifice mounting hardware to hold
the inlet orifice in this position.
3. Check the radial clearance of the blower by passing
a 0.09 in. (2.3 mm) gauge wire completely around
the circumference of the condenser orifice and the
condenser blower.

Evaporator Fan Blower Alignment
1. Loosen the inlet orifices on the sides of the blower
housing.
2. Center the blower wheel in the blower housing with
equal overlap on both inlet orifices. The overlap on
each orifice should be approximately 0.15 in. (3.8
mm).
3. Tighten the hub pinch bolts that hold the blower
