INSPECT BACK WINDOW (DEFOGGER WIRE)

NOTICE:

INSPECT BACK WINDOW (DEFOGGER WIRE)

  1.  Turn the ignition switch ON.
  2.  Turn the defogger switch ON.
  3. Inspect the voltage at the center of each defogger wire, as shown in the illustration.

 

Standard voltage

 

HINT: If there is approximately 10 V, the wire may be broken between the center of the wire and the end on the battery side. If there is no voltage, the wire may be broken between the center of the wire and the end on the ground side.

  1.  Place the voltmeter positive (+) lead against the defogger wire on the battery side.
  2.  Place the voltmeter negative (-) lead with the foil strip against the wire on the ground side.
  3.  Slide the positive (+) lead from the battery side to the ground side.
  4.  The point where the voltmeter deflects from approx 10 V to 0 V is the place where the defogger wire is broken.

HINT: If the defogger wire is not broken, the voltmeter indicates 0 V at the positive (+) end of the defogger wire but gradually increases to about 12 V as the meter probe moves to the other end.

2. INSPECT WIRE HARNESS (FRONT WINDOW DEICER WIRE)
