PRINTED-HEATER 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 circuit tester at rear window glass
centre A.
Condition is good if it indicates about 6V.
3. If 12 V 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 (0V).
4. If 0 V is indicated at A, there is a break in the positive
terminals from A. Defect where the voltage changes
suddenly (12 V) in the same method described above.

Inspection procedure 14
Rear defogger does not operate.
Probable cause
If the rear defogger does not operate when the rear defogger switch is turned
on (timer operates for 20 minutes), the cause is probably a malfunction of the
A/C-ECU power supply system (earth).
Malfunction of connector or harness

Malfunction of A/C-ECU
Can an operating sound be heard when the rear defogger switch
is operated?NOInspection procedure 15 (Refer to P.55-52.)
YES
Replace the A/C-ECU.
