Mirror Switch Test
- To perform mirror switch test, remove mirror switch. Leave electrical connector connected. Place mirror select switch in LEFT position. (On vehicles with separate mirror switches, test applies to LEFT and RIGHT mirror switches).
- Hold mirror directional switch in positions specified in table. Check voltage at terminals specified in table. See appropriate MIRROR SWITCH TEST
table. 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 positions specified in table. Using an ohmmeter, check continuity of mirror switch by probing both terminals as specified in table. Place mirror select switch in RIGHT position. Repeat continuity test.
NOTE:
On most models with mirror select switch, duplicate wire colors are used in circuit between mirror switch and mirror motors: one set of wires leads to driver mirror motors, other set leads to passenger mirror motors. When checking for voltage on models with duplicate wire colors, probe wire terminal as specified in table. 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 in table. 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 the same color.
