Test C: A Single Mirror Does Not Function With Switch Logic

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

Normal Operation
The exterior mirror control switch is supplied voltage from the central junction box (CJB) through circuit 1523 (DG) and ground through circuit 57 (BK). The exterior mirror control switch activates the LH exterior mirror up and down positions by switching voltage and ground on circuits 940 (DB/OG) and 945 (YE/BK). The exterior mirror control switch activates the LH exterior mirror left and right positions by switching voltage and ground on circuits 942 (RD/OG) and 945 (YE/BK). The exterior mirror control switch activates the RH exterior mirror up and down positions by switching voltage and ground on circuits 943 (VT/OG) and 945 (YE/BK). The exterior mirror control switch activates the RH exterior mirror left and right positions by switching voltage and ground on circuits 944 (DG/OG) and 945 (YE/BK). The exterior mirror control switch must be in the appropriate (left or right) position for the desired mirror to operate.

This pinpoint test is intended to diagnose the following:
- Exterior mirror control switch
- Exterior mirror motor
- Wiring terminals or connectors
