Mirror Motor Test

  1. To perform mirror motor test, remove mirror switch. Disconnect electrical connector. Using a 12-volt source, connect positive and negative leads to specified wire terminals. See appropriate MIRROR MOTOR TEST table.
  2. Reverse positive and negative leads on these wire terminals. Reverse leads again. Mirror motor should move up and down or left and right as specified.
NOTE: Most models with mirror select switch use duplicate wire colors in circuit between mirror switch and mirror motors: one set of wires leads to left mirror motors, other set leads to right mirror motors. When testing mirror motors on models with duplicate wire colors, connect battery positive lead to one wire terminal and battery negative lead to other wire terminal as specified. If mirror motor does not operate, leave positive lead connected. Disconnect negative lead and connect to other wire terminal of same color. If mirror motor does not operate, leave negative lead connected. Disconnect positive lead and connect to other wire terminal of same color.
