A/C System Service

Evacuation

Use only service equipment that is U.L.-listed and is cer-

tified to meet the requirements of SAE J2210 to remove

HFC-134a (R-134a) from the air conditioner system.

CAUTION: Exposure to air conditioner refrigerant and

lubricant vapor or mist can irritate eyes, nose and throat.

Avoid breathing the air conditioner refrigerant and lubri-

cant vapor or mist.

If accidental system discharge occurs, ventilate work

area before resuming service.

R-134a service equipment or vehicle air conditioner sys-

tems should not be pressure tested or leak tested with

compressed air.

Some mixtures of air and R-134a have been

shown to be combustible at elevated pressures and can

result in fire or explosion causing injury or property

damage. Never use compressed air to pressure test R-

134a service equipment or vehicle air conditioner sys-

tems.

Additional health and safety information may be obtained

from the refrigerant and lubricant manufacturers.

1. When an A/C System has been opened to the atmo-

sphere, such as during installation or repair, it must

be evacuated using a R-134a refrigerant Recovery/

Recycling/Charging System. (If the system has been

open for several days, the receiver/dryer should be

replaced, and the system should be evacuated for

several hours.)

2. Connect a R-134a refrigerant Recovery/Recycling/

Charging System to the vehicle, as shown, follow-

ing the equipment manufacturer's instructions.

NOTE: If low-pressure does not reach more than 93.3

kPa (700 mmHg, 27.6 in.Hg) in 15 minutes, there is

probably a leak in the system. Partially charge the

system, and check for leaks (see Leak Test).

Troubleshooting

Tips and Precautions

Before Troubleshooting

Check applicable fuses in the appropriate fuse/relay

box.

Check the battery for damage, state of charge, and

clean and tight connections.

Check the alternator belt tension.

CAUTION:

Do not quick-charge a battery unless the battery

ground cable has been disconnected, otherwise you

will damage the alternator diodes.

Do not attempt to crank the engine with the battery

ground cable loosely connected or you will severely

damage the wiring.

Handling Connectors

Make sure the connectors are clean and have no loose

wire terminals.

Make sure multiple cavity connectors are packed with

grease (except waterproof connectors).

All connectors have push-down release type locks.

LOCKING TAB

Some connectors have a clip on their side used to

attach them to a mount bracket on the body or on

another component. This clip has a pull type lock.

Some mounted connectors cannot be disconnected

unless you first release the lock and remove the con-

nector from its mount bracket.

BRACKET
Never try to disconnect connectors by pulling on

their wires; pull on the connector halves instead.

Always reinstall plastic covers.

Before connecting connectors, make sure the termi-

nals are in place and not bent.

BENT TERMINAL

Check for loose retainer and rubber seals.

The backs of some connectors are packed with

grease. Add grease if necessary. If the grease is con-

taminated, replace it.
