Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
SGI233
To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
SGI234
Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
Replace inner and outer races of tapered roller bearings and
needle bearings as a set.
Arrange the disassembled parts in accordance with their
assembled locations and sequence.
Do not touch the terminals of electrical components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.
After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.
Use only the fluids and lubricants specified in this manual.
Use approved bonding agent, sealants or their equivalents
when required.
Use tools and recommended special tools where specified for
safe and efficient service repairs.
When repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.
Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.

GI-5

PBIC0648E
7. Disconnect electrical connector.
8. Disconnect the quick connector as follows.
a. Put mating marks on tubes and connectors for correct instal-
lation.
PBIC0709E
b. Hold the connector while pushing in buttons, and pull out the
tube.
CAUTION:
The tube can be removed when the buttons are completely
depressed. Do not twist it more than necessary.
Do not use any tools to remove the quick connector.
Keep the resin tube away from heat. Be especially careful
when welding near the tube.
Prevent acid liquid such as battery electrolyte etc. from
getting on the resin tube.
Do not bend or twist the tube during installation and
removal.
PBIC0713E
To keep clean the connecting portion and to avoid damage
and foreign materials, cover them completely with plastic
bags or something similar.

TROUBLE DIAGNOSIS
CHECKING DISCHARGE AIR
1. Press mode switch four times and DEF button.
2. Each position indicator should change shape.
3. Confirm that discharge air comes out according to the air distri-
bution table. Refer to ATC-27, "
Discharge Air Flow" .
Intake door position is checked in the next step.
If NG, go to AT C - 5 9 , "
Mode Door Motor Circuit" .
If OK, continue with next check.
NOTE:
Confirm that the compressor clutch is engaged (visual inspection)
and intake door position is at FRESH when the DEF is selected.

AT C
In the most extreme case (very low ambient) the blower starting delay will be 150 seconds as described
above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above
56°C (133°F), at which time the blower speed will increase to the objective speed.
Start Up From Usual or HOT SOAK Condition (Automatic mode)
The blower will begin operation momentarily after the A/C button is pushed. The blower speed will gradually
rise to the objective speed over a time period of 3 seconds or less (actual time depends on the objective
blower speed).
Blower Speed Compensation
Sunload
When the in-vehicle temperature and the set temperature are very close, the blower will be operating at low
speed. The low speed will vary depending on the sunload. During conditions of low or no sunload, the blower
low speed is usual low speed (approx. 4V). During high sunload conditions, the auto amp causes the blower
fan speed to increase.(Approx. 7V)
Fan Speed Control Specification
COMPONENT DESCRIPTION
Fan Control Amplifier
The fan control amplifier is located on the heater & cooling unit. The
fan control amp. receives a gate voltage from the auto amp. to step-
lessly maintain the blower fan motor voltage in the 4 to 12 volt range.
DIAGNOSTIC PROCEDURE FOR BLOWER MOTOR
SYMPTOM: Blower motor operation is malfunctioning under starting
fan speed control.
