Condition
Some customers may comment that the left or right outside rearview mirror glass shakes or flutters at normal driving speeds.
Cause
-
The mirror may have been accidentally pushed in manually or obstructed while folding.
-
The mirror actuator screws may be loose, allowing the mirror to move.
-
The metal spring may not have enough tension to hold the mirror from moving.
Correction
Follow the procedure below to correct this condition.
1. The power folding mirrors should be cycled three complete times to relearn the mirror positions. Then perform a road test and check the mirror
glass for stability. If stability is not corrected, proceed to Step 2.
2. Remove the mirror glass. Refer to Mirror Face Replacement in SI.
3. Verify the torque on the four retaining screws on the actuator.
Tighten
Tighten the screws to 1.13-1.6 Nm (10-14 lb in).
4. Bend the metal spring up to increase the tension engagement to the mirror housing 13 mm (1/2 in).
5. Install the glass assembly by pressing firmly, taking care not to allow the spring finger to unseat from its intended track in the mirror housing.
Road test the vehicle. If stability is not improved, replace the mirror assembly. Refer to Power Mirror Replacement in SI.
Parts Information
If replacing the mirror assembly, see Mirror in Group 16.068 of the appropriate Parts Catalog for part numbers and usage.
