CLEAN OR REPLACE AIR CONDITIONING FILTER
Remove the glove compartment door assembly.
Remove the air filter case Click here.
Remove the clean air filter Click here.
Visually inspect the surface of the clean air filter.
If the clean air filter is contaminated with foreign matter, clean or replace it according to the maintenance schedule.
Note
Some filters are not able to be cleaned.
FINAL INSPECTION
Check the operation of the body parts.
Hood
Auxiliary catch operates properly.

Front and rear doors
Door locks operate properly.
Doors close properly.
Back door
Door lock operates properly.
Door closes properly.
Seats
Seat adjusts easily and locks securely in any position.
Front seatback locks securely in any position.
Rear seatback locks securely in any position.
Folding-down rear seatbacks lock securely.
Be sure to deliver a clean vehicle. Especially check:
Steering wheel

CORROSION INSPECTION
INSPECT REFRIGERANT AMOUNT OF AIR CONDITIONER
This method uses a manifold gauge set to locate problem areas. Read the manifold gauge pressure when these conditions are established.
Test conditions:
Temperature at the air inlet with the air recirculation switch set at RECIRC is 30 to 35°C (86 to 95°F).
Engine is running at 1500 rpm.
All doors are fully open.
Blower speed control switch is at HI.
A/C switch is on.
Gauge readings (Reference):
Normally functioning refrigeration system.
| Gauge Reading | ||||||
|---|---|---|---|---|---|---|
|
The A/C system periodically changes between normal and improper function due to moisture in the refrigerant system.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
| During operation, pressure on low pressure side cycles between normal and vacuum | Moisture in refrigeration system freezes at expansion valve orifice, causing temporary stop of cycle. However, when melted, normal state is restored. |
|
|
The A/C system does not function effectively due to insufficient refrigerant.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
|
Gas leakage from refrigeration system |
|
|
The A/C system does not function effectively due to poor circulation of the refrigerant.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
|
Refrigerant flow obstructed by dirt in condenser | Condenser clogged | Replace condenser |
The A/C system does not function or functions intermittently because the refrigerant does not circulate.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
|
|
Refrigerant does not circulate |
|
The A/C system does not function effectively due to overcharged refrigerant or insufficient cooling of the condenser.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
| Pressure extremely high on both low and high-pressure sides |
|
|
|
The A/C system does not function due to air in the refrigeration system.
CAUTION:
The low-pressure piping may be very hot and cause serious burns.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
|
Air in refrigeration system |
|
|
The A/C system does not function effectively due to an expansion valve malfunction.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
|
Problem with expansion valve |
|
Replace expansion valve |
The A/C system does not function due to a defective compressor.
| Symptom | Probable Cause | Diagnosis | Corrective Action |
|---|---|---|---|
|
Internal leakage in compressor |
|
Repair or replace compressor |
