assembly towards right side of vehicle and remove rear A/C-heater
assembly.
5) To install, reverse removal procedure. Ensure all wiring
and hoses are clear and not pinched. Tighten bolts and nuts to
specification. See TORQUE SPECIFICATIONS .
Removal (Ram Pickup - Front)
1) Disconnect negative battery cable. Drain cooling system.
In engine compartment, remove coolant hoses from heater core tubes.
Remove coolant overflow bottle.
2) Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Disconnect refrigerant lines from
evaporator and plug or cover all openings in A/C system. Remove
instrument panel. See INSTRUMENT PANEL. Remove Powertrain Control
Module (PCM) and position aside. DO NOT disconnect 60-pin connector
from PCM.
3) Remove attaching nuts from studs on engine compartment
side of dash panel. Remove defrost duct. Disconnect electrical
connectors. Remove attaching nuts from studs in passenger compartment
side of dash panel. Remove A/C-heater assembly from vehicle. See
Fig. 5 .
4) Place A/C-heater assembly upside-down on work bench.
Remove screw securing floor duct to bottom of A/C-heater assembly and
slide floor duct off of center heat duct adapter. Unsnap center heat
duct adapter from bottom of A/C-heater assembly housing. Remove screw
hidden behind adapter. Remove remaining screws and separate A/C-heater
assembly.
Installation
Ensure mode door pivot pins are properly inserted in holes.
To complete installation, reverse removal procedure.
A/C-HEATER CONTROL PANEL R & I
Removal & Installation (Dakota & Durango)
1) Disconnect negative battery cable. On models equipped with
A/T, unlock ignition switch. Set parking brake and place gear selector
lever in "L" position. If equipped, set tilt steering column in lowest
position.
2) On all models, carefully pry bezel away from instrument
panel to disengage clips. Unplug connectors from cigarette lighter and
auxiliary power outlet. Disconnect fog light switch (if equipped).
Remove A/C-heater control panel screws.
3) Pull control panel outward enough to disconnect wiring
connector, vacuum harness, and temperature control cable. Remove A/C-
heater control panel. To install, reverse removal procedure. Adjust
temperature control cable. See TEMPERATURE CONTROL CABLE ADJUSTMENT .
Removal & Installation (Ram Pickup)
1) Disconnect negative battery cable. Reach under driver's
side of instrument panel, near transmission tunnel and unplug A/C-
heater control panel to A/C-heater assembly vacuum harness connector.
Disconnect vacuum harness from center air duct.
2) On models equipped with A/T, unlock ignition switch. Set
parking brake and place gear selector lever in "L" position. If
equipped, set tilt steering column in lowest position.
3) On all models, remove screw securing cluster bezel to
instrument panel. See Fig. 6. Carefully pry bezel away from instrument
panel to disengage clips. Unplug connectors from cigarette lighter and
auxiliary power outlet.
4) Remove 4 screws attaching A/C-heater control panel. Pull
control panel outward enough to disconnect wiring connector, vacuum
harness and temperature control cable. Remove A/C-heater control

test system. Ensure A/C system is operating properly.
Orifice Tube Replacement Kit (Villager)
1) Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Drain engine coolant to a level below
thermostat. Remove upper radiator hose and bracket to gain access to
condenser end of liquid line. Remove condenser-to-evaporator liquid
line from vehicle.
2) Locate orifice tube in metal portion of liquid line, at
indentation. See Fig. 20. Make a 4" (102 mm) index line on liquid line
with indentation at the midpoint. Cut a 2.5" (63.5 mm) section from
liquid line with indentation in the middle, at least 1" (25.4 mm) from\
start of closest bend. Clean out liquid line to remove contaminants.
3) Lubricate orifice tube replacement kit compression nuts
and rings with refrigerant oil and install on liquid line. See Fig. 21
. Ensure flow direction arrow points toward evaporator. Ensure index
line on liquid line is properly aligned for installation. Tighten
compression nuts to 65-70 ft. lbs. (88-95 N.m).
4) To complete installation, reverse removal procedure.
Lubricate "O" rings with refrigerant oil. Evacuate, charge and leak
test system. Ensure A/C system is operating properly.
