System Description/YD Engine Models without
Common Rail and K9K Engine Models
=NJEL0463The rear window defogger system is controlled by the time control unit. Therear window defogger operates
only for approximately 15 minutes.
Power is supplied at all times
through 20A fuse [No. 7, located in the fuse block (J/B)]
to rear window defogger relay terminal 5 (B7 relay models) or 3 (B6 relay models)
through 10A fuse [No. 13, located in the fuse block (J/B)]
to rear window defogger relay terminal 6 (B6 relay models).
through 15A fuse [No. 5, located in the fuse block (J/B)]
to time control unit terminal 9.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 10, located in the fuse block (J/B)]
to the rear window defogger relay terminal 1 and
to time control unit terminal 1.
Ground is supplied to terminal 5 of the rear window defogger switch throughbody grounds M28 and M67.
When the rear defogger switch is turned ON, ground is supplied
through terminal 3 of the rear defogger switch
to time control unit terminal 3.
Terminal 13 of time control unit then supplies ground to the rear window defogger relay terminal 2.
With power and ground supplied, the rear window defogger relay is energized.
Power is supplied
through terminals 5 and 7 of the rear window defogger relay (B6 relay models)or
through terminal 3 of the rear window defogger relay (B7 relay models)
to the rear window defogger and door mirror defogger.
The rear window defogger has an independent ground.
With power and ground supplied, the rear window defogger filaments heat and defog the rear window.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.
