Mirror Switch Test

To perform mirror switch test, remove mirror switch. Leave electrical connector connected. Place mirror select switch in LEFT position. (On Brougham, test applies to both mirror switches).
Hold mirror directional switch in specified positions. See appropriate MIRROR SWITCH TEST table. Check voltage at specified terminals. Place mirror select switch in RIGHT position. Repeat voltage test.
Disconnect mirror switch connector. Place mirror select switch in LEFT position. Hold mirror directional switch in specified positions. Using an ohmmeter, check continuity of mirror switch by probing specified terminals. Place mirror select switch in RIGHT position. Repeat continuity test.

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 checking for voltage on models with duplicate wire colors, probe specified wire terminal. If voltage is not present, probe other wire terminal of same color. When checking continuity, connect ohmmeter positive lead to one switch terminal and ohmmeter negative lead to other switch terminal as specified. If there is no continuity, leave positive lead connected. Disconnect negative lead and connect to other switch terminal of same color. If there is no continuity, leave negative lead connected. Disconnect positive lead and connect to other switch terminal of same color.
