REAR WINDOW DEFOGGER
GENERAL INFORMATIONM1543000100319
Rear Defogger operation
The defogger relay turns ON if the defogger switch
built-in the A/C-ECU is turned ON when the ignition
switch is in the "ON" position. When the defogger
relay turns ON, power is supplied to the defogger
and the defogger is activated. The defogger comes
with a timer function that causes the defogger switch
to automatically turn OFF in about 11 minutes after
the defogger switch is turned ON.
TROUBLESHOOTINGM1543000701013
The rear window defogger is controlled by the
A/C-ECU. For troubleshooting, refer to GROUP 55-

ON-VEHICLE SERVICE
PRINTED HEATER LINES CHECKM1543001800311
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 six volts.
3. If 12 volts 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 volts).
4. If 0 volts is indicated at A, there is a break in the
positive terminals from A. Defect where the
voltage changes suddenly (12 volts) in the same
method described above.
