2) Ensure system is properly charged with correct amount of
refrigerant. Evacuate and charge system as necessary. Ensure receiver-
drier is not clogged. Check compressor belt for proper tension. Check
for clogged expansion valve. Check compressor operation. Repair or
replace components as necessary.
INSUFFICIENT AIRFLOW
Check for air leakage at air duct joint. Check for frost on
evaporator. Ensure blower motor is operating properly. Check for
obstructed air intake.
INSUFFICIENT COOLING
Ensure system is properly charged with correct amount of
refrigerant and free of air and moisture. Evacuate and charge system
as necessary. Ensure receiver-drier is not clogged. Ensure sufficient
airflow through condenser exists. Check compressor belt for proper
tension. Check compressor operation. Repair or replace compressor as
necessary. Check for clogged expansion valve. Replace expansion valve
as necessary. Check A/C compressor clutch coil.
INTERMITTENT COOL AIR
Check for air or moisture in system. Evacuate and charge
system as necessary. Check for expansion valve malfunction. Replace
expansion valve if necessary. Check compressor belt for proper
tension.
TESTING
* PLEASE READ THIS FIRST *
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG RESTRAINT
SYSTEM article.
NOTE: For testing procedures not covered in this article, see
HEATER SYSTEM article.
A/C SYSTEM PERFORMANCE
1) Park vehicle out of direct sunlight. Install A/C gauge
set. Start engine and allow it to idle at 1000 RPM. Turn A/C on. Set
A/C controls to recirculated air, panel (vent) mode and full cold

SERVICE PRECAUTIONS. Turn ignition switch to LOCK position. Disconnect
negative battery cable. Shield cable end. Disconnect positive battery
cable. Remove battery. Wait at least 60 seconds before continuing.
2) Remove air bag module. Place air bag module on ground at
least 20 feet away from people or objects. Air bag module face (trim
cover) must face upward to prevent movement of air bag module when it
is deployed.
3) Make a harness with two 20-foot (or longer) wires. Connec\
t
wires at one end of this harness to stripped wires of SRS Air Bag
Adapter Harness "B" (MB628919) for driver-side air bag, or SRS Air Bag\
Adapter Harness "A" (MB686560) for passenger-side air bag. See Fig. 2.
4) Wrap connections with insulating tape. Temporarily connect
other end of harness wires together to prevent unexpected air bag
deployment. Connect appropriate adapter harness to air bag module
connector. Place a tire without a rim over the air bag module so rim
hole surrounds air bag module. Stack 3 more tires on top of first
tire. Connect ends of 20-foot wires to terminals of a 12-volt battery.
5) After air bag module deploys, let it cool off and allow
dust to settle for at least 30 minutes before approaching. Tightly
seal deployed air bag module in a strong vinyl bag and dispose of air
bag as you would any other part.
DEPLOYED AIR BAG CLEAN-UP
WARNING: Vehicle interior will contain sodium hydroxide powder, a
by-product of air bag deployment. Since this powder can
irritate skin, eyes, nose and throat, wear safety glasses,
rubber gloves and long-sleeved shirt during clean-up.
1) Avoid breathing powder from air bag deployment. Begin
clean-up by putting tape over air bag exhaust vent to prevent
additional powder from escaping into vehicle interior. Use a vacuum
cleaner to remove any residual powder from A/C-heater outlets and
vehicle interior.
2) Turn blower motor to low for a few minutes and exit
vehicle. Turn blower motor off. Vacuum any other powder expelled from
plenum. Vacuum interior a second time to recover all powder. Avoid
kneeling or sitting on unclean areas. Wrap deployed air bag in heavy
vinyl plastic and dispose of it as you would any other part.
POST-COLLISION INSPECTION
When a vehicle has been involved in a collision, certain
components of the passive restraint system must be inspected or
replaced. See PASSIVE RESTRAINT SYSTEM INSPECTION article in the
GENERAL INFORMATION section for post-collision inspection information.
REMOVAL & INSTALLATION
WARNING: Follow air bag service precautions to prevent accidental air
bag deployment and personal injury. See SERVICE PRECAUTIONS.
Replace faulty SRS components; DO NOT repair or disassemble.
Handle all SRS components carefully.
DRIVER-SIDE AIR BAG MODULE & CLOCKSPRING
Removal
1) Before proceeding, see SERVICE PRECAUTIONS. Reactivate
SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Ensure front wheels are in straight-ahead position. Remove
lower covers from air bag module. Remove air bag module mounting nut
