No VERIFY the customer concern. | Component Tests Heated Rear Window Grid Wire Test - Using a bright lamp inside the vehicle, visually inspect the grid wire from the outside. A broken grid conductor line will appear as a brown spot.
- Run the engine at idle. Set the heated rear window switch and lights to ON. The heated rear window indicator light should illuminate.
- Working inside the vehicle with a multimeter, contact the broad red/brown strips on the heated rear window positive lead to battery side and negative lead to ground side. The meter should read 10-13 volts. A lower voltage reading indicates a loose heated rear window ground wire connection at the heated rear window ground wire screw.
- Contact a ground point with the negative lead of the multimeter. The voltage reading should not change.
- With the negative lead of the multimeter grounded, touch each grid line of the heated rear window at its pinpoint with the positive lead. A reading of approximately six volts indicates that the line is OK. A reading of zero volts indicates that the line is broken between the midpoint and the battery side of the grid line. A reading of 12 volts indicates that the circuit is broken between the midpoint of the grid line and ground.
- INSTALL a new heated rear window glass.
