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
  1. Inspect for a short circuit and repair it, if necessary.
  2. Replace fuse F1.
Is the repair complete?		 - System OK -
4
  1. Turn on the ignition, with the engine OFF.
  2. 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 -

  1. From beneath the instrument panel, reach up and press one of the retaining tabs for the trim panel on the electric control mirror switch.
  2. 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 -

  1. Disconnect the electric control mirror switch connector.
  2. Turn ONthe ignition, with the engine OFF.
  3. 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
  1. Turn on the ignition, with the engine OFF
  2. 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
  1. Verify that the electric control mirror switch has been reconnected.
  2. On the passenger door, remove the black plastic escutcheon to expose the electric control mirror connector.
  3. Disconnect the connector at the passenger door electric control mirror.
  4. Connect a voltmeter between terminal 4 and terminal 3.
  5. 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
  1. Disconnect the electric control mirror switch connector.
  2. Use an ohmmeter to measure the continuity between terminal 5, and the electric control mirror switch and terminal 3 at the power mirror connector.
  3. 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 Ω 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
  1. If the electric control mirror switch was previously disconnected for testing, reconnect the switch.
  2. Disconnect the electric control mirror connector at the passenger door power mirror.
  3. Connect a voltmeter between terminal 4 and terminal 5.
  4. 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
  1. Disconnect the electric control mirror switch.
  2. 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.
  3. 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 Ω Go to Step 16  Go to Step 15

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
