Mode Control Motor
Test
Connect battery power to the No. 4 terminal of themode control motor and connect ground to the No.
I terminal.
Using a jumper wire, connect the No. 8 termjnal in-dividually to the No. 1, 2, 3, 6 and 7 terminals, inthat order. Each time the short circuit is made. themode control motor should run smoothly and stop.
NOTE: lf the mode control motor does not run whenshorting the first terminal, short that te.minal againafter shorting the other terminals.
The mode control motor is OK if it runs when jumping
the tirst terminal again.
lf the mode control motor does nol run in steD 2, re-move it, and check the mode control linkage anddoors for smooth movement. lf the mode controllinkage and doors move smoothly, replace the mode
control motor.

Test
1.Connect battery power to the No. 1 terminal of the
recirculation control motor, and connect ground to
the No. 2 and No. 4 terminals; the recirculation con-
trol motor should run smoothly.
Disconnect the No. 2 or No. 4 terminal from ground;
the recirculation control motor should stop at FRESH
or RECIRCULATE.
CAUTION: Never connect the battery in the oppo-
site dilection.
NOTE: Don't cycle the recirculation control motor
for a long time.
lf the recirculation control motor does not run in step
1, remove it, and check the recirculation control link-
age and door lor smooth movement. If the recircu-
lation control linkage and door move smoothly,
reDlace the recirculation control motor.

control motor, and remove the wire harness clip from
it.
2. Remove the two screws, the recirculation
motor and the flange collaf.

A/C Service Tips and Precautions
The air conditioner system uses HFC-134a (R-134a) refrigerant and polyalkyleneglycol {PAG) refrigerant oil (ND-OlL 8: P/N
38897-PR7-A01AH or 38899 - PR7 - A01), 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 equipment; damage to the air
conditioner system or your servicing equipment will result.
Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-l34a
from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and lubricant vapor ot mist can irritate eyos, nose.nd throat, Avoid
breathing th€ air conditionsr rofrigerant 8nd lubricant vapo. 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 comp.essed
atf,
@ some mixtures ol air and R-13i[a have been shown to be combustible at olevat6d pre3sures and cln resuh
in fire or explosion causing iniury or property damage. Nover uso compressed air to prossure te3t R-13,[8 service equip-
ment or vehicle air condition6r 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 Jittings 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 recovering the system. use a R-134a refrigerant Recovery/Recycling/Charging System; don't release refrigerant
into the atmosphere.
6. Add refrigerant oil after replacing the following parts.
NOTE:
. To avoid contamination, do not return the oil tothe container once dispensed, and never mix itwith other refriger-
ant oils.
.lmmediatelyafterusingtheoil,replacethecaponthecontainerandseal it to avoid moisture absorption.
. Do notspillthe refrigerant oil onthevehicle; it maydamagethe painu itthe refrigerant oil contacts the paint, wash
it off immediately.

Tips and Precautions
Never try to disconnect connectors by pulling on their
wires; pull on lhe connector halves instead.
Alwavs reinstall Dlastic covers.
Before connecting connectors, make sure the termi-
nals are in Dlace and not bent.
a Check lor loose retainer and rubber seals.
The backs of some connectors are packed with
grease. Add grease if needed. lf the grease is contami-
nated, reolace it.

Bef ore Troubleshooting
a Check applicable tuses 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:
a Do not quick-charge a battely unless the battery
ground cable has been disconnected. otherwise
you will damage the alternator diod€s.
a Do not attempt to crank the engine with the bat-
tery ground cable loosely connected or you willse-
verely damage the wiring.
a The originsl radio has a coded theft plotection cir-
cuit. Be sure to get the customel's code numbel
before- disconnecting the battsry.- removing the No. 47 (7.5 A) fuse from tho
under-hood luse/relay box.- removing the radio.
Atter service. leconnect Dower to the radio and
tum it on. When the word "CODE" is displayed,
enter the customer's 5-digit code to restore radio
ooeration.
Handling Connectors
a Make sure the connectors are clean and have no loose
wire terminals.
a Make sure multiple cavity connectors are packed with
grease (except watertight connectors).
a All connectors have push-down release type locks.
LOCKING TAB
LOCKING TAB
Some connectors have a clip on their side used to at-
tach 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 tirst release the lock and remove the con-
nector from its bracket.
