REAR WINDOW DEFROSTER T BATTERY POSITIVE VOLTAGE 45UOTX-18C -- FAULTY PORTION OV BATTERY POSITIVE VOLTAGE 45UOTX-18; Rear Window Defroster Switch (Refer to section U.) Rear Window Defroster Filament 1. Turn the rear window defroster switch ON. 2. Connect the (+) terminal of a voltmeter to the center of each filament and the (-) terminal to the body. The stan- dard voltage at the center of each filament is approx. 6V. If the meter indication is high, there is a short circuit be- tween the center and the grounded side of the filament. If the indication is low or zero, the fault is between the center and positive side. REPAIRING FILAMENT Caution Use only paint thinner or ethyl alcohol for clean- ing. Other solvents can damage the surrounding filament. 1. Use paint thinner or ethyl alcohol to clean the damage section of the filament. 2. Apply tape to both sides of the damaged section of fila- ment. 3. Using a small brush or marking pen, apply silver paint (part no. 2835 77 600) or equivalent to the damaged sec- tion. 4. Use a blow dryer heated to 60°C (140°F) for 30 minutes or let the paint set for 24 hours at 20°C (68°F) to let it dry completely. Do not use the rear window defroster until the paint is dry.

u AIR CONDITIONER 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-25.) 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 in- let. 7. Wait until the air conditioner outlet temperature stabi- lizes. 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. Stabilized condition Blower inlet temperature: 30-35°C (86-95°F) High-pressure side: 1.38-1.56 MPa (1 4.0-1 6.0 kgflcm*, 200-227 psi) 8. After the air conditioner stabilizes, read the dry and wet thermometer at the air inlet. 9. Calculate the relative humidity from the chart below by comparing the wet- and dry-bulb readings.

UNDERCOATING, PVC PAINTING AND RUST PREVENTIVE WAX TREATMENT Air dry a minimum of 4-6 hours [20°C (68OF)l. L Heat dry a minimum of 30-40 minutes [60°C (140°F)]. Color coat i Apply coating after PVC paint film is thoroughly dry. Sanding is not necessary if all oil and grease were completely removed. Conditions such as air pressure, paint viscosity, etc. can be same as for ordinary body coating. -1 Done in same way as for ordinary body coating. Nozzle type A Nozzle type B RUST PREVENTIVE WAX TREATMENT WAX APPLICATION PROCEDURE Preparation of equipment 1. Prepare equipment suitable for the wax chosen. 2. Use the correct nozzle, spray pattern, and in- jection pressure based on instructions provided for the wax. 3. If necessary, clean the nozzle with thinner before beginning work. Preparation of vehicle (or parts) 1. Scrape mud, etc. off the wax application area. 2. Dry any water collected at the wax application area. 3. The temperature of the vehicle body should be kept at more than 10°C (50°F) during the opera- tion. 4. Close all windows of the vehicle. Caution When repairing a damaged part, complete painting first, then apply the wax. The reasons are: a) The wax is sometimes dissolved by heat [more than 120°C (248OF)I during the drying process, resulting in deteriorated anticor- rosion effects. b)lf the wax applied before painting is smeared over the paint application surface, poor painting will result because the wax repels the paint.
