Using a jumper wire. connect the No. 7 terminalindividually to the No, 2,3, 4,5 and 6 terminals in
that order. Each time the connection is made. the
mode control motor should run smoothly and stop.
lf the mode control motor does not run when jump-
ing the first terminal, jump that terminal again afterjumping the other terminals. The mode control
motor is OK it it runs when jumping the first termi-
nal again.

1. Disconnect the negative cable from the battery.
2. From under the hood, open the cable clamp, then dis-
connect the heater valve cable from the heater valve
arm. Turn the heater valve arm to the fullv ooened
oosition as shown.
When the engine is cool, drain the engine coolant
from the radiator (see section 10).
@ Do not remove the rldiator cap when
the engine is hot; the engine coolant is under pres-

A/C Service Tips and Precautions
The air conditioner system uses HFC-'134a (R-134a) refrigerant and polyalkyleneglycol {PAG) refrigerant oil*, which are not
compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do
not attempt to use R-12 servicing equipmenu damage to the air conditioner system or your servicing equipment will
resutr.
*KEIHIN SP-10:
. P/N 38897 - Pl3 - A01AH: 120 m{ (4 fl.oz, il.2 lmp.oz)
. P/N 38899 - Pl3 - A01: 40 mf 11113tl.oz,1.4 lmp.oz)
Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a
from the air conditioner system,
CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or misl can irritats eyes, nose and throat. Avoid
breathing the air conditioner refrigerant and lubricant vapor or mist,
lf accidental system discharge occurs, ventilate work area before resuming service.
R 134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed
air.
E@ Some mixtures of air and R-13,1a have been shown to be combustible at elevat€d pressures and can result
in fire or explosion causing iniury or property damage. Never use complessed air to pressure test R-l3,[a service equip-
ment or vehicle air conditioner systems.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
1. Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
2. Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't
remove the caps or plugs until just before you reconnect each line.
3. Before connecting any hose or line. apply a few drops of refrigerant oilto the O-ring,
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When discharging the system, use a R l34a refrigerant recovery/recycling/charging station; don't release refrigerant
into the atmosphere.
6. Add refrigerant oil after replacing the following parts.
Note these items when handling refrigerant oil:
o To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriger-
ant oils.
. lmmediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
. Do not spill the refrigerant oil on the vehicle; it may damage the painu if the refrigerant oil contacts the paint, wash
it off immediately.

lf the compressor is marginally operable. run the
engine at idie speed, and let the air conditioner
work for a few minutes. then shut the engine off.
Disconnect the negative cable from the battery.
Recover the refrigerant with a recovery/recycling/
charging station (see page 22-59).
Disconnect the condenser fan connector. Remove
the compressor clutch connector and the wire har-
ness clip from the condenser fan shroud, then dis-
connect the compressor clutch connector. Remove

Troubleshooting
Tips and Precautions
Bef ore Troubleshootin g
. 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 thc engins wilh the battery
ground cable loosely connected or you will severely
damage the wiring.
Handling Connestors
. Make sure the connectors are clean and have no loose
wire terminals,
. N4ake sure multiple cavity connectors are packed with
grease (except water-tight connectors).
. All connectors have push-down release type locks.
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.

CONNECTORBRACKET
Never try to disconnect connectors by pulling on
their wires; pull on the connector halves instead.
Alwavs reinstall olastic covers.
Before connecting connectors, make sure the termi-

. Check for loose retainers and rubber seals.
RETAINER
The backs of some connectors are oacked with
grease. Add grease if necessary. lf the grease is con
taminated. reolace it.
