Timer Function

WARNING: This page is about a different car, the 2011 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

BCM transmits rear window defogger ON signal to rear window defogger relay (integrated in fuse block J/B) for approximately 15 minutes when rear window defogger switch (A/C auto amp.^*1 and A/C amp.^*2 ) is turned ON while ignition switch is ON. Rear window defogger and door mirror defogger are operated.
Timer is cancelled when rear window defogger switch is pressed again during timer operation. BCM stops output of rear window defogger switch signal. The same reaction also occurs during timer operation when ignition switch is turned OFF.
^*1 : With auto A/C

^*2 : With manual A/C
