DEFOGGER

GENERAL DESCRIPTION

M1543000100353

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 17 minutes after the defogger switch is 
turned ON.

DEFOGGER DIAGNOSIS

M1543000701068

The defogger is controlled by the A/C-ECU. For trou-
bleshooting, refer to GROUP 55, Auto A/C Diagnosis 
− Symptom Chart 

P.55-68

1. Run the engine at 2,000 r/min. Check the heater element 

with the battery at full.

2. Turn "ON" the rear window defogger switch. Measure the 

heater element voltage with an ohmmeter at the rear 
window glass centre A. Condition is good if it indicates about 
6 V.

3. If 12 V is indicated at A, there is a break in the negative 

terminals from A. Move the test probe slowly to the 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.
