Without defogger timer
NOTE
Rear window defogger on cars without a timer. Power feed: ignition switch ON or START → 20A fuse [3] (10U) → /G to the defogger grid. The rear window defogger switch (toggle, OFF/ON) controls the ground side of the grid — pressing ON closes the path to body ground. There is no timeout; the grid is energized continuously until the operator presses OFF or the ignition is switched off.
