Chrysler Town & Country/Voyager, Dodge Caravan, Plymouth Voyager. Manual — part 135
(9) Place compressor front cover on a flat surface
with neck of cover facing up. Using a brass drift, press
out seal assembly (Fig. 13).
(10) Remove dowel pins, valve plates, and steel valve
plate gasket. Discard steel gasket (Fig. 14).
INSTALLATION
(1) Install dowel pins in front compressor body.
(2) Install cleaned valve plates.
(3) Install steel gasket.
(4) Clean crankshaft and coat lightly with refriger-
ant oil.
(5) Lubricate crankshaft seal seat cavity of front
housing with refrigeration oil.
(6) Lubricate crankshaft lip seal and seal O-ring
with refrigeration oil. Then install lip seal in front
cover using a socket that contacts the outer diameter of
the lip seal (Figs. 15 and 16).
(7) Install seal snap ring (Fig. 17).
(8) Lubricate front cover O-ring with refrigeration
oil and carefully place it in seal groove.
(9) Install lip seal protector on shaft (Fig. 18).
(10) Install front cover to front compressor body.
(11) Install compressor through-bolts and finger
tighten only. After bolts have been finger tightened,
torque to 29N
Im (260 in. lbs.).
(12) Install felt shaft seal and retainer (Fig. 19) into
front housing.
CAUTION: Refer to Oil Level in the Refrigerant Ser-
vice Procedures section for further details.

(13) Install refrigeration oil (500 SUS) into the com-
pressor through the suction port.
(14) Check compressor operation for smoothness by
rotating crankshaft at least five full revolutions.
(15) Check front housing clutch coil alignment pin
for proper installation.
(16) Install clutch assembly.
(17) Install compressor.
(18) Evacuate and charge refrigerant system.
COMPRESSOR HIGH-PRESSURE RELIEF VALVE
REMOVAL AND INSTALLATION
(1) Discharge the refrigerant system.
(2) Rotate the high pressure relief valve counter-
clockwise and separate relief valve from the vehicle
(Fig. 20).
To install, Reverse the preceding operation using a
new O-ring seal. Evacuate and charge the refrigerant
system.

COMPONENT DIAGNOSIS
CONDENSATE WATER DRAINAGE
Condensation that accumulates on the bottom of the
evaporator housing is drained from a rubber tube
through the dash panel and on to the ground. This tube
must be kept open to prevent condensate water from
collecting in the bottom of the heater A/C unit housing
(Fig. 1).
The tapered end of the drain tube is designed to keep
contaminants from entering the heater A/C unit hous-
ing. If the tube is pinched or blocked, condensate
cannot drain, causing water to back up and spill into
the passenger compartment. It is normal to see con-
densate drainage below the vehicle. If the tube is
damaged, it should be replaced.
BLOWER MOTOR VIBRATION AND/OR NOISE DI-
AGNOSIS
The blower speed switch, in conjunction with the
resistor block (Fig. 2), supplies the blower motor with
varied voltage.
CAUTION: Stay clear of the blower motor and resistor
block (Hot). Do not operate the blower motor with the
resistor block removed from the heater-A/C housing.
Refer to the Blower Motor Vibration/Noise chart in
this section for diagnosis.
BLOWER MOTOR ELECTRICAL DIAGNOSIS
Refer to the Blower Motor Electrical System Diagno-
sis chart in this section. Also refer to Group 8W, Wiring
Diagrams for more information.
