REAR WINDOW DEFOGGER
REAR WINDOW DEFOGGER
Component Parts and Harness Connector LocationINFOID:0000000003533066
System DescriptionINFOID:0000000003533067
The rear window defogger system is controlled by BCM (body control module) and IPDM E/R (intelligent
power distribution module engine room).
The rear window defogger operates only for approximately 15 minutes.
Power is supplied at all times
• through 15A fuses (No. 43, 46, and 47 located in the IPDM E/R)
• to rear window defogger relay and heated mirror relay (located in the IPDM E/R)
• through 50A fusible link (letter f, located in the fuse and fusible link box)
• to BCM terminal 70.
With the ignition switch turned to ON or START position, power is supplied
• through ignition switch
• to rear window defogger relay (located in the IPDM E/R)
• through 10A fuse (No. 59, located in the fuse and relay box)
• to BCM terminal 38
• through 10A fuse [No. 8, located in the fuse block (J/B)]
• to front air control terminal 14.
Ground is supplied
• to BCM terminal 67
• to front air control terminal 1
• through body grounds M57, M61 and M79
