Electrically Heated Rear Window and Door Mirrors

FAULT DIAGNOSIS HINTS
The electrically heated rear window and door mirrors are activated by turning the ignition switch to the Drive position.
1. Check that fuses 9 and 18 are intact and supplied with current.
2. Check the voltage on relay 113.
3. Check the voltage on relay 113 while switch 116 is activated.
4. Activate relay 113 and check the electrically heated rear window connections and that the window heating element is supplied with current.
5. Check the connectors, wiring harness and ground connections.

If there is an open circuit in the diode on relay 113, the relay holding circuit will not operate.
