Defogger Test
- Reconnect the 8P connector to the mirror actuator, turn the ignition switch ON (II) and the mirror defogger switch is ON.
- Check voltage between the No. 3 and No. 4 terminals of the 8P connector. There should be battery voltage. If there is no voltage, check for an open in the wire. If voltage is as specified and the mirror fails to warm up, replace the mirror defoggers.
