Mirrors

Intermittent

Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections

Heated Mirrors Inoperative

Step	Action	Values	Yes	No
1	Test the rear window defogger. Does the rear window defogger work?		Go to Step 4	Go to Step 2
2	Repair the rear window defogger before proceeding with the outside rearview mirror diagnosis. Is the repair complete?		Go to Step 3
3	Test the outside rearview mirror defoggers. Does the repair of the rear window defogger system also fix the condition with the outside rearview mirror defoggers?		System OK	Go to Step 4
4	Test fuses E21 and F19. Are fuses E21 or F19 open?		Go to Step 5	Go to Step 6
5	Test for a short circuit and repair if necessary. Replace the fuse. Is the repair complete?		System OK
6	On the side of the vehicle that has the malfunctioning defogger, remove the black plastic plate from the trim panel side of the door. Disconnect the electrical connector from the outside rearview mirror. Turn ON the ignition. Turn ON the defogger. Using a voltmeter, backprobe terminal 2 (ORN) at the electrical connector to the outside rearview mirror. Does the voltmeter indicate the specified value?	11-14 V	Go to Step 9	Go to Step 7
7	Repair the open circuit between fuse E21 and the defogger relay. Is the repair complete?		System OK	Go to Step 8
8	Turn ON the ignition. Turn ON the defogger. Use a voltmeter to fuse F19 and the defogger relay terminal 86. Does the voltmeter indicate the specified value?	11-14 V	Go to Step 10	Go to Step 9
9	Replace the defogger switch. Is the repair complete?		System OK
10	Replace the defogger relay. Does the outside rearview mirror work?		System OK	Go to Step 11
11	Turn OFF the ignition. Disconnect the electrical connector to the outside rearview mirror. Use an ohmmeter to measure the resistance between terminal 1 (BLK) of the outside rearview mirror connector and ground. Does the ohmmeter indicate the specified value?	0 ohms	Go to Step 13	Go to Step 12
12	Repair the open ground circuit for the outside rearview mirror. Is the repair complete?		System OK
13	Replace the defective outside rearview mirror. Is the repair complete?		System OK

Power Mirrors Inoperative

Step	Action	Values	Yes	No
1	Inspect the electric control mirror's left-and-right and up-and-down adjustments. Is the mirror operating for either the left-and-right or up-and-down adjustment?		Go to Step 12	Go to Step 2
2	Inspect fuse F1. Is fuse F1 open?		Go to Step 3	Go to Step 4
3	Inspect for a short circuit and repair it, if necessary. Replace fuse F1. Is the repair complete?		System OK
4	Turn on the ignition, with the engine OFF. Measure the voltage at fuse F1. Is the voltage at fuse F1 equal to the specified value?	11-14 V	Go to Step 6	Go to Step 5
5	Repair the open power supply circuit for fuse F1. Is the repair complete?		System OK
6	From beneath the instrument panel, reach up and press one of the retaining tabs for the trim panel on the electric control mirror switch. While pressing one of the retaining tabs, pull the switch assembly away from the instrument panel so that the connector is visible. Is the connector properly connected to the electric control mirror switch?		Go to Step 8	Go to Step 7
7	Connect the connector to the electric control mirror switch. Is the repair complete?		System OK
8	Disconnect the electric control mirror switch connector. Turn ONthe ignition, with the engine OFF. Connect a voltmeter between terminal 6 and terminal 8. Does the voltmeter indicate the specified value?	11-14 V	Go to Step 13	Go to Step 9
9	Turn on the ignition, with the engine OFF Measure the voltage at terminal 6. Does the voltage equal the specified value?	11-14 V	Go to Step 10	Go to Step 11
10	Repair the open circuit between ground and terminal 8. Is the repair complete?		System OK
11	Repair the open circuit between the F1 fuse and the electric control mirror switch. Is the repair complete?		System OK
12	Inspect the left-and-right adjustment for the electric control mirror. Is the left-and-right adjustment working for the electric control mirror?		Go to Step 18	Go to Step 13
13	Verify that the electric control mirror switch has been reconnected. On the passenger door, remove the black plastic escutcheon to expose the electric control mirror connector. Disconnect the connector at the passenger door electric control mirror. Connect a voltmeter between terminal 4 and terminal 3. Observe the voltmeter while operating the electric control mirror switch to select the left-and-right adjustment. Does the voltmeter indicate the specified voltage in one direction, and the same voltage with reverse polarity when operated in the opposite direction?	11-14 V	Go to Step 17	Go to Step 14
14	Disconnect the electric control mirror switch connector. Use an ohmmeter to measure the continuity between terminal 5, and the electric control mirror switch and terminal 3 at the power mirror connector. Use an ohmmeter to measure the continuity between terminal 4 at the electric control mirror switch and terminal 4 at the power mirror connector. Does the ohmmeter indicate the specified value for both measurements?	0 ohms	Go to Step 16	Go to Step 15
15	Repair the open circuit between the electric control mirror switch and the electric control mirror connector. Is the repair complete?		System OK
16	Replace the electric control mirror switch. Is the repair complete?		System OK
17	Replace the electric control mirror. Is the repair complete?		System OK
18	If the electric control mirror switch was previously disconnected for testing, reconnect the switch. Disconnect the electric control mirror connector at the passenger door power mirror. Connect a voltmeter between terminal 4 and terminal 5. Observe the voltmeter while operating the power mirror switch to select the up-and-down adjustment. Does the voltmeter indicate the specified voltage in one direction, and the same voltage with reverse polarity when operated in the opposite direction?	11-14 V	Go to Step 17	Go to Step 19
19	Disconnect the electric control mirror switch. Use an ohmmeter to measure the continuity between terminal 1 at the electric control mirror switch and terminal 5 at the electric control mirror connector. Use an ohmmeter to measure the continuity between terminal 4 at the electric control mirror switch and terminal 4 at the electric control mirror connector. Does the ohmmeter indicate the specified value for both measurements?	0 ohms	Go to Step 16	Go to Step 15
