PINPOINT TEST 3: A SINGLE MIRROR DOES NOT FUNCTION WITH SWITCH LOGIC

Normal Operation

The exterior rear view mirror switch uses circuits (GY/BR), (V/O), (G/BR), (GY/O) and (GY) to control the exterior mirror movement.

- When power is directed through circuit (V/O, GY/O) and ground through circuit (GY), the LH/RH exterior mirror operates left.
- When ground is directed through circuit (V/O, GY/O) and power through circuit (GY), the LH/RH exterior mirror operates right.
- When power is directed through circuit (GY/BR, G/BR) and ground through circuit (GY), the LH/RH exterior mirror operates down.
- When ground is directed through circuit (GY/BR, G/BR) and power through circuit (GY), the LH/RH exterior mirror operates up.
