Power Mirror Position Sensor Test
- Disconnect electrical connector from power mirror motor. Connect three 1.5-volt dry cell batteries together in series. See Fig 1. Connect dry cell positive lead to terminal No. 11 and negative lead to terminal No. 8. Connect positive lead of voltmeter to terminal No. 10 and negative lead to terminal No. 8.
- While watching voltmeter, apply battery voltage between terminals No. 3 and 13, reversing polarity as necessary to move mirror in both directions. As mirror moves, voltage should gradually and smoothly change from 0.0-0.9 volt to 2.8-5.0 volts.
- Disconnect voltmeter and battery voltage from motor connector terminals (leave dry cell assembly connected). Connect positive lead of voltmeter to terminal No. 9 and negative lead to terminal No. 8.
- Apply battery voltage between terminals No. 12 and 13, reversing polarity as necessary to move motor in both directions. As mirror moves, voltage should gradually and smoothly change from 0.0-0.9 volt to 2.8-5.0 volts. If voltage is not as specified, replace power mirror.
