POWER MIRROR SWITCH TEST
Remove power mirror switch. Check for continuity between specified terminals at switch. (Scheme 1) See POWER MIRROR SWITCH CONTINUITY TEST table. If continuity does not exist, replace switch.
| Switch Position | Terminals | |
|---|---|---|
| Left Switch | ||
| Off (Neutral) | (1) | |
| Up | 3 & 4; 7 & 8 | |
| Down | 4 & 7; 3 & 8 | |
| Left | 4 & 9; 7 & 8 | |
| Right | 4 & 7; 8 & 9 | |
| Right Switch | ||
| Off (Neutral) | (1) | |
| Up | 1, 7 & 8; 2 & 4 | |
| Down | 1, 2 & 8; 4 & 7 | |
| Left | 1, 7 & 8; 4 & 10 | |
| Right | 2, 8 & 10; 4 & 7 | |

Scheme 1
POWER MIRROR MOTOR TEST
Disconnect power mirror motor connector. Apply battery voltage between specified terminals (reverse polarity to move motor in opposite direction). See POWER MIRROR MOTOR TEST table. (Scheme 2) Replace motor if it does not operate as specified.
| Mirror Direction | Terminals No. | |
|---|---|---|
| With Memory | ||
| Left/Right | 8 & 7 | |
| Up/Down | 3 & 7 | |
| Without Memory | ||
| Left/Right | 6 & 5 | |
| Up/Down | 4 & 5 | |

Scheme 3
POWER MIRROR POSITION SENSOR TEST
- Disconnect power mirror motor connector. Connect three 1.5-volt dry cell batteries together in series. (Scheme 4) Connect dry cell positive lead to terminal No. 9 and negative lead to terminal No. 12. Connect positive lead of voltmeter to terminal No. 10 and negative lead to terminal 12.
- While watching voltmeter, apply battery voltage to terminals No. 3 and 7, 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. If voltage is not as specified, replace power mirror. If voltage is as specified, go to next step.
- Disconnect voltmeter and battery voltage from motor connector terminals (leave dry cell assembly connected). Connect positive lead of voltmeter to terminal No. 11 and negative lead to terminal No. 12.
- Apply battery voltage between terminals No. 7 and 8, 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. If voltage is not as specified, replace power mirror.
Scheme 4
Liquid Crystal Mirror Test
Remove rear view mirror. Using jumper wires, apply positive battery voltage to terminal No. 1 and negative battery terminal to terminal No. 4 at rear view mirror connector. (Scheme 5) Connect positive lead of voltmeter to terminal No. 2 and negative lead to terminal No. 3. Press mirror switch. Observe voltmeter and shine an electric light on face of mirror. Battery voltage should be present and face should change from bright to dark. Replace mirror as necessary.
