CHECK HEATED WINDSHIELD DEFROSTER SYSTEM
Start the engine.
Check that the windshield glass (heated windshield defroster LH and heated windshield defroster RH) becomes warm by operating the No. 2 combination switch assembly (windshield deicer switch).
Confirm that heated windshield defroster system operation stops after approximately 4 minutes.
Note
If the ambient temperature is 5°C (41°F) or higher, or if a malfunction of the ambient temperature sensor (thermistor assembly) is detected, the EHW NO. 1 relay and EHW NO. 2 relay will be deactivated and the No. 2 combination switch assembly (windshield deicer switch) indicator light will blink.
