TROUBLESHOOTING
There is noise when the engine is running.
Kind of Noise (Parenthe-
sized is how noise
sounds.)SymptomCauseRemedy
AM, FM: Ignition noise
(Popping, snapping,
crackling, buzzing)
Popping sound becomes
faster with the increase
of engine speed.

The noise is lost with
ignition switch turned to
ACC.
Mainly due to the
spark plugs.

Due to noise circula-
tion from elsewhere

Noise from the engineCheck the noise capacitor
and earth cable and
replace if necessary. (See
Fig. 1 and Fig. 2.)
AM, FM: Defogger noise
(1) (Murmuring)Occurs when the defogger
switch is turned to ON and
OFF.Noise produced by spark-
ing when the defogger
switch is turned to ON/
OFF enters the glass
antenna.Check the noise capacitor
and replace if necessary.
(See Fig. 1.)
AM, FM: Defogger noise
(2) (Snapping noise)Occurs when the defogger
switch is turned to ON.Noise produced by current
flowing in the defogger
enters the glass antenna.Check the choke coil and
replace if necessary.
(See Fig. 3.)
AM, FM: Defogger noise
(3) (Scratching, gaggling)Occurs when the defogger
switch is turned to ON with
print heater wire broken.Noise produced by spark-
ing where print heater is
broken enters the glass
antenna.Repair the print heater.
AM, FM: Wiper motor
noise (Humming, wheez-
ing)Sound becomes faster with
the increase of wiper speed
and is lost when the wiper is
stopped.Caused by sparking in
wiper motor brush.Replace the wiper motor.
FM: Mirror motor noise
(Humming, wheezing)Occurs when electric mirror
operates.Caused by sparking in
mirror motor brush.Replace the electric
motor.
Other electrical compo-
nents–Noise is emitted by some
electrical components in
long use.Repair or replace electri-
cal components.
Static electricity (Crack-
ling, crinkling)
Noise is stopped when
the vehicle comes to a
complete stop.

Noise becomes louder
when the clutch is
released.Occurs when parts or
wiring move for some
reason and contact metal
parts of the body.Put parts or wiring into
position.
Various noises are produced
by body parts.Due to electrical detach-
ment of the hood, exhaust
pipe and muffler, suspen-
sion, etc. from the body.Tighten mounting bolts
securely. In many cases,
remedy of one part does
not eliminate the problem
due to incomplete earthing
elsewhere.
Caution
(1) Never let the noise filter contact a high tension cable. The noise filter could break down.
(2) Check that there is no external noise. This check is necessary to prevent misidentification of noise
sources.
(3) Noise prevention should be performed by eliminating noise sources in the descending order of loudness.

INSTALLATION SERVICE POINT
ACOMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of
oil according to the procedures described below, and then
install the compressor.
1. Measure the amount (X m
) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount
120 to 140 m
– X m
= Y m

NOTE
(1)“120 to 140 ml” is the amount of oil filled in a new
compressor.
(2) Y m
indicates the amount of oil in the refrigerant
line, the condenser, the cooling unit etc.
INSPECTION
REFRIGERANT-TEMPERATURE SWITCH SIMPLE
CHECK
When the A/C is off, check that there is continuity between
the refrigerant-temperature switch terminals. If no, replace
the compressor assembly.
COMPRESSOR MAGNETIC CLUTCH OPERATION
INSPECTION
Connect the battery (+) terminal to the compressor side
terminal, and earth the battery (–) terminal to the body of
the compressor. The condition is normal if the sound of the
magnetic clutch (click) can be heard.AView A

REMOVAL SERVICE POINTS
AFAN MOTOR AND SHROUD ASSEMBLY
REMOVAL
Remove the clamp bolt of the power steering oil cooler pipe.
Remove the fan motor and shroud assembly while pulling
the power steering oil cooler pipe toward you.
BDISCHARGE HOSE / LIQUID PIPE A
DISCONNECTION
Plug the open end of the disconnected hose and the opening
in the cooling unit not to let foreign matter get into them.
Caution
Seal the hoses completely, otherwise the compressor
oil and receiver will absorb water vapour easily.
CCONDENSER REMOVAL
Move the radiator to the engine side and then lift up the
condenser to remove it.
