Step 4-Step 6:
Exterior Rear View Mirror Switch Test:
Normal Operation
Under normal operation, the exterior mirror control switch uses circuit (L/G), (Y/V), (GY/O) or (V/O) to control mirror movement.
- When power is received through circuit (L/G)/(Y/V) and grounded through (GY), LH/RH exterior will operate LEFT.
- When ground is received through circuit (L/G)/(Y/V) and powered through (GY), LH/RH exterior will operate RIGHT.
- When power is received through circuit (GY/O)/(V/O) and grounded through (GY), LH/RH exterior will operate UP.
- When ground is received through circuit (GY/O)/(V/O) and power through (GY), LH/RH exterior will operate DOWN.
Possible Causes
- An open in circuit (GY/O), (V/O), (L/G) or (Y/V) between the exterior mirror control switch and either the LH or RH exterior rear view mirror
- Inoperative exterior mirror control switch
- Inoperative exterior mirror motor
