Operation Description
• When rear window defogger switch is turned ON while ignition switch is ON, the rear window defogger switch transmits rear window defogger switch signal to BCM.
• BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
• Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and
operate when rear window defogger relay turns ON.
• Rear window defogger ON is displayed when front air c ontrol (manual A/C) or A/C switch assembly (auto A/
C) receives signals.
Timer function
• BCM turns rear window defogger relay ON for approx imately 15 minutes when rear window defogger switch
is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door
mirror defogger) operate.
• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.

WITH MANUAL A/C
WITH MANUAL A/C : DescriptionINFOID:0000000009463031
• The rear window defogger is operated by pre ssing the rear window defogger switch ON.
• The indicator lamp in the rear window defogger switch illuminates while the rear window defogger is ON.
WITH MANUAL A/C : Component Function CheckINFOID:0000000009463032
1. CHECK REAR WINDOW DEFOGGER SWITCH FUNCTION
1. Push ignition switch to ON.
2. Press rear window defogger switch.
3. Check that the indicator lamp of t he rear window defogger switch illuminates.
4. Press rear window defogger switch.
5. Check that the indicator lamp of t he rear window defogger switch extinguishes.
Is the inspection result normal?
YES >> Rear window defogger switch function is OK.
NO >> Refer to DEF-19, "WITH MANUAL A/C : Diagnosis Procedure"
.
WITH MANUAL A/C : Diagnosis ProcedureINFOID:0000000009463033
Regarding Wiring Diagram information, refer to DEF-11, "Wiring Diagram".
1.CHECK REAR WINDOW DEFOGGER RELAY OPERATION
1. Push the ignition switch to ON.
2. Check that an operation noise of rear window defogger relay [located in fuse block (J/B)] can be heard
when pressing the rear window defogger switch ON and OFF.
Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 5.
2.CHECK FUSE
Check if Fuse 22 from the rear window defogger relay output is blown.
Is the fuse blown?
YES >> Replace the blown fuse after repairing the affected circuit.
NO >> GO TO 3.
3. CHECK FOR VOLTAGE FROM THE REAR WINDOW DEFOGGER RELAY
1. Connect a voltmeter between Fuse block (J/B) and ground.
2. While pressing the rear window defogger switch ON and OFF, check for voltage between Fuse block (J/B)
and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Perform rear window defogger relay diagnosis. Refer to DEF-26, "Diagnosis Procedure"
