Test B: Single Mirror Completely Inoperative

Turn ignition switch to LOCK position. Disconnect mirror control switch 8-pin harness connector C740. Disconnect inoperative mirror 5-pin harness connector. Measure resistance between mirror control switch harness connector C740 terminal No. 3 (Yellow/Red wire) and inoperative mirror harness connector terminal No. 2 (Yellow on driver's side; Yellow/Green wire on passenger's side). See Figure and Figure . If resistance is greater than 10 k/ohms, repair open in appropriate circuit. See WIRING DIAGRAMS  . If resistance is 5 ohms or less, replace mirror control switch.
