GENERAL PROCEDURES
Contaminated Refrigerant Handling
1. CAUTION: If contaminated refrigerant is detected, DO NOT recover the refrigerant
into your recovery/recycling equipment.
Recover the contaminated refrigerant using suitable recovery- only equipment designed for
capturing and storing contaminated refrigerant.
zThis equipment must only be used to recover contaminated refrigerant to prevent the
spread to other vehicles.
z If this equipment is not available, contact an A/C repair facility in your area with the
correct equipment to carry out this repair.
2. Determine and correct the cause of the customer's initial concern.
3. NOTE: Residual refrigerant oil in the suction accumulator/drier must be drained and measured
for correct oil system matching. For additional information, refer to Refrigerant Oil Adding in this
section.
The suction accumulator/drier cannot be cleaned and a new suction accumulator/drier must be
installed.
Remove the suction accumulator/drier. For additional information, refer to Section 412 - 03 .
4. Clean the A/C evaporator core and the A/C condenser core by flushing. For additional information, refer to Air Conditioning (A/C) System Flushing in this section.
5. Install the new suction accumulator/drier. For additional information, refer to Section 412 - 03 .
6. Correctly oil match the system. For additional information, refer to Refrigerant Oil Adding in this
section.
7. Evacuate and charge the system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
8. Dispose of contaminated refrigerant according to all federal, state and local regulations.

GENERAL PROCEDURES
Vacuum Hose Repair —
Mini-Tube
1. Measure the length of the damaged area of the mini-tube vacuum hose.
2. Cut a piece of standard 1/8 inch inner diameter vacuum hose approximately 25 mm (1 inch longer than the damaged area of the mini- tube vacuum hose).
3. Cut off the mini-tube vacuum hose on each side of the damaged area.
4. WARNING: Read the warning information on the product label to prevent possible
personal injury.
Dip the mini- tube hose ends in commercially available paint thinner containing methyl ethyl
ketone (MEK). This solvent will seal the mini- tube in the vacuum hose.
5. Insert the ends of the mini- tube vacuum hose approximately 9 mm (3/8 inch) into the ends of
the standard 1/8 inch repair vacuum hose section.
6. Shake the repair joint after assembly to make sure the solvent is dispersed and the vacuum line is not plugged.
7. Test the system for a vacuum leak in the repair area. zUse the Vacuum Tester or equivalent.

DESCRIPTION AND OPERATION
Air Distribution
NOTE:
The air distribution system of this vehicle cannot be equipped with a cabin air filter.
There are two sources of air available to the air distribution system:
zoutside air
z recirculated air
Recirculated air is only used during MAX A/C.
Air distribution within the vehicle is determined by the function selector switch position. Airflow control
doors are used to direct airflow within the air plenum chamber. Vacuum control motors (18A318) are
used to position these airflow control doors. Refer to Section 412 - 00 for a description and operation of
each of the system functions.
The air distribution system is designed to provide airflow from the defrost nozzle when no vacuum is
applied to any of the vacuum control motors. This is done to prevent a situation where defrost cannot
be obtained due to a system vacuum leak.
Air enters the passenger compartment from the:
zinstrument panel A/C register (19893).
z heater outlet floor duct (18C433).
z windshield defroster hose nozzle (18490).
z side window demisters.
Passenger compartment air is exhausted from the vehicle through open windows or body air vents.
Instrument Panel Registers
There are A/C registers on the left and right sides of the instrument panel and in the center instrument
panel finish panel.
The LH and RH A/C registers are only serviceable as assemblies.
The center A/C registers are not serviceable as assemblies. The registers are installed with the
instrument panel center finish panel assembly. Component Locations SECTION 412-
