Heated Glass Element Grid Test
PRINTED-HEATER LINE CHECK
1. Run engine at 2,000 r/min. Check heater element with battery at full.
2. Turn ON rear window defogger switch. Measure heater element voltage with voltmeter at rear window glass center A.
Condition good of indicating about 6 V.
3. If battery positive voltage is indicated at A, there is a break in the negative terminals from A.
Move test bar slowly to negative terminal to detect where voltage changes suddenly (0 V).
4. If 0 V is indicated at A, there is a break in the positive terminals from A. Detect where the voltage changes suddenly (battery positive voltage) using the same method described in step 3.
PRINTED-HEATER LINE REPAIR
REQUIRED MATERIALS
- Thinner
- Lead-free gasoline
- Tape
- Fine brush
- Conductive paint
1. Clean disconnected area with lead-free gasoline. Tape along both sides of heater element.
2. Mix conductive paint thoroughly. Thin the required amount of paint in a separate container with a small amount of thinner and paint break three times at 15 minutes intervals.
3. Remove tape and leave for a while before use (circuit complete).
4. When completely dry (after 24 hours) finish exterior with a knife.
CAUTION: Clean glass with a soft cloth (dry or damp) along defogger heater element.
