Rear Window Defogger Timer

WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2005 Acura NSX, 2004 Acura NSX, 2003 Acura NSX-T, 2003 Acura NSX, and 2002 Acura NSX-T. However, it is still accessible from the selected car via links, so may be relevant.

The rear window defogger is controlled by the integrated control unit. When the defogger switch in the combination switch is pushed, it sends a signal to the defogger timer in the integrated control unit and the defogger stays on for 25 minutes or until the ignition switch is switched off. The indicator light in the switch shows when the defogger is on. See Fig 1 and Fig 2 .
