Function Test: Defogger

  1. Connect the No. 3 and No. 6 terminals with a jumper wire, and check for voltage between the No. 3 terminal and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch ON (II).
    • If there is no voltage or neither warms up, check for:
      • - an open in the ORN and ORN/WHT wires.
      • - blown No. 4 (7.5 A) fuse in the driver's under-dash fuse/relay box.
      • - poor ground (G601, G651).
    • If only one fails to warm up, check its defogger.
    • If both warm up, check the defogger switch.
