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 (driver's side mirror) may not have enough tension to hold the mirror from moving.

Correction

 

Follow the procedure below to correct this condition.

1.<LI type=1>The power folding mirrors should be cycled three times to relearn position. Then perform a road test and check the mirror glass for stability. If stability is not fixed, proceed to Step 2. <LI type=1>Remove the mirror glass. Refer to Mirror Face Replacement in SI. <LI type=1>Check the torque on the four retaining screws on the actuator. Tighten

Tighten the screws to 1.13-1.6 N·m (10-14 lb in).

<LI type=1>Bend the metal spring (driver's side mirror) up to increase tension engagement to the mirror housing 13 mm (1/2 in).

2.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.

Hi guys, 2008 GMC Sierra, the mirror jiggles going down the road, bracket assembly is tight, is the mirror it self easy to get off with out breaking, and then what can be done to tighten. Thanks for any help.

 

On the GMT-800, the mirror can be pryed off it's circular rotating base by unclipping the actual mirror by prying the clips outward. With the mirror off, you can then tighten the torx screws that hold the rotating base tight.

 

I'm not sure on the new body style, but this is worth a shot.

I have the same problem except it is with my passenger side mirror....the mirror shakes when I am driving because it is loose. It is a 2001 Sierra. I am not sure what you mean by your directions though but I looked underneath the mirror and unclipped the plastic piece on the bottom but did not find a screw or anything to tighten it....could you elaborate a little on your process or is there a DIY somewhere?

 

Thanks
