FILAMENT
inspection
1. Turn the rear window defroster switch ON.
2. Connect the (+) terminal of the voltmeter to the center of
each filament and the (-) terminal to the body. The stan-
dard voltage at the center of each filament is approximate-
ly 6V. If the meter indication is high, there is a short circuit
between the center and the grounded side of the filament.
If the indication is low or zero, the malfunction is between
the center and positive side.
Repairing
7. Use paint thinner or ethyl alcohol to clean the damaged part
of the filament.
2. Attach tape to both sides of the damaged part of the filament.
3. Using a small brush or marking pen, coat the damaged part
with silver paint (part no. 2835 77 600) or equivalent.
4. Let the paint set for 24 hours at 25OC (77OF) to let it dry
completely. (If a blow dryer is used to heat it to 150°C
(302OF), it can be dried in about 30 minutes.)
Note
l Do not use the rear window defroster until the paint
is dry.
l Do not use gasoline or sDmiiar solvents to clean the
damaged part.

Performance test
After finishing repairs, conduct a performance test of the air
conditioning system as follows.
1. Connect the manifold gauge set. (Refer to page U-32.)
2. Start the engine and keep the engine speed at
1,500 rpm.
3. Operate the air conditioner at maximum cooling.
4. Open all windows and doors.
5. Place a dry-bulb thermometer in the center ventilator outlet.
6. Place a dry and wet thermometer close to the blower inlet.
7. Wait until the air conditioner outlet temperature stabilizes.
Stabilized condition
Blower inlet temperature: 25-35*C (77-95*F)
High-pressure side:
1,177-1,619 kPa (12.0-16.6 kg/cm’, 171-235 psi)
Note
l If the high-pressure side becomes too high, pour
cool water on the condenser. If It is too low, cover
the front of the condenser.
8. After the air conditioner stabilizes, read the dry and wet ther-
mometer at the air inlet.
9. Calculate the relative humidity from the chart below by com-
paring the wet- and dry-bulb readings.

the difference between the inlet dry-bulb and outlet dry-bulb
temperatures.
11. Verify that the intersection of the relative humidity and tem-
perature difference is in the shaded zone.
