1. Remove the outside air temperature sensor
(see page 21-68).
2. Dip the sensor in ice water, and measure the resistance. Then pour warm water on the sensor,
and check for a change in resistance.
3. Compare the resistance reading between terminals No. 1 and No. 2 of the outside air temperature
sensor with the specifications shown in the graph;
the resistance should be within the specifications.
4. If the resistance is not as specified, replace the outside air temperature sensor (see page 21-68). 1. Remove the front grille cover (see page 20-163).
2. Lift the tab (A) to release the lock, then remove the
outside air temperature sensor (B) from the bracket.
Disconnect the 2P connector (C) from the outside
air temperature sensor.
3. Install the sensor in the reverse order of removal.

Power Transistor Test
POWER TRANSISTOR (To 12 V Power source on vehicle)JUMPER WIRE
A
1. Remove the passenger’s dashboard undercover
(see page 20-104).
2. Disconnect the 4P connector from the power transistor.
3. Measure the resistance between terminals No. 3 and No. 4 of the power transistor. It should be
about 1.5 k .
 If the resistance is within the specifications, go to step 4.
 If the resistance is not within the specifications, replace the power transistor.
NOTE: Also check the blower motor. Power
transistor failure can be caused by a defective
blower motor. 4. Carefully release the lock tab on terminal No. 1
(YEL) (A) in the 4P connector, then remove the
terminal and insulate it from body ground.
5. Reconnect the 4P connector to the power transistor.
6. Make sure the YEL wire is completely isolated, then supply 12 V to cavity No. 1 with a jumper wire.
7. Turn the ignition switch to ON (II), and check that the blower motor runs.
 If the blower motor does not run, replace the power transistor.
NOTE: A faulty blower motor can cause the
power transistor to fail. If the power transistor is
replaced, also check the blower motor for
binding, and replace it if necessary.
 If the blower motor runs, the power transistor is OK.

A/C System Noise Check (cont’d)
5. Turn the ignition switch to LOCK (0), and check the
drive belt for excessive wear, oil contamination,
improper routing, or a faulty belt tensioner
(see page 4-30). Correct any problems found. Start
the engine, run the A/C system, and check if the
noise is coming from the drive belt, the belt
tensioner or any of the pulleys. Repair or replace
any faulty components.
6. Listen for noises coming from the A/C lines, the A/C hoses, the condenser, the evaporator, the receiver/
drier, or the expansion valve, and check these
items:
 Noises caused by A/C components touching other components or the body. Reroute or
insulate the A/C component(s) as needed, and
recheck for noise.
 Loose, damaged or excessively worn A/C components or mounting hardware. Repair or
replace the faulty component(s) or hardware, and
recheck for noise.
 A moaning noise coming from the A/C suction line. If there is a moaning noise, check the
system refrigerant charge (see page 21-92). If the
refrigerant charge is OK, replace the receiver/
dryer.
7. Check the operation of the A/C compressor clutch:  Make sure compressor clutch engages withoutslipping. If the clutch does not engage,
troubleshoot the A/C compressor clutch circuit
(see page 21-62). If the compressor clutch slips,
replace the complete clutch assembly (see page
21-86).
 Make sure the compressor clutch disengages. If the clutch does not disengage, do the A/C
compressor clutch check (see page 21-85). If the
compressor clutch is OK, replace the A/C
compressor (see page 21-83).
 Make sure the compressor clutch cycles normally. If the compressor clutch is cycling rapidly, the
A/C system is probably low on refrigerant due to
a leak. Do the refrigerant leak check (see page
21-93). If the refrigerant charge is OK, and there
are no leaks, troubleshoot the A/C compressor
clutch circuit. 8. Listen with a stethoscope for noises coming from
the A/C compressor, and check these items:
 The noise changes when the compressor clutch disengages. If the noise does not change when
the A/C compressor disengages, the noise may
be caused by an engine-related component.
Probe the engine area with a stethoscope to
pinpoint the noise.
 The A/C system operating pressures are normal. If the system pressures are abnormal,
troubleshoot the problem using the pressure test
table in the A/C system check (see page 21-99).
Correct the pressure-related problem(s), and
recheck for noise.
 The compressor hose connections, mounting brackets, and fasteners are in good condition. If
any of these components are loose, damaged, or
excessively worn, repair or replace the faulty
component(s), and recheck for noise. If these
components are in good condition, and the noise
is still present, replace the A/C compressor
(see page 21-83).

Tips and Precautions
Before Troubleshooting
Handling Connectors
22-3
General Troubleshooting Information
A A A
A
1. Check applicable fuses in the appropriate fuse/relay box.
2. Check the battery for damage, state of charge, and clean and tight connections.
 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 s everely damage the
wiring.
 Make sure the connectors are clean and have no loose wire terminals.
 Make sure multiple cavity connectors are packed with dielectric grease (except watertight connectors).
 All connectors have push-down release type locks (A).  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
connector from its mount bracket (A).
 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 terminals (A) are in place and not bent.
