I have had my 07 Tahoe LT3 into the dealer for excessive vibration in the driver side mirror. They have replaced the mirror and it still vibrates. Anyone else have this problem. I called the dealer back to let them know it still vibrates and they basically told me that I will have to live with it. Before I go back to the dealer, is there anyone else dealing with the same issue?? Thanks!!!!!!!

 

Yes, I have it on mine (wifey's) also. We haven't taken it to the dealer yet, but it is a pain. I've tried moving it all the way each way to lock it down, put the mirrors all the way in, and have pushed on the glass to get it to seat better because they snap in. Nothing has worked. We plan on taking it to the dealer soon.

 

Outside rearview mirror vibration problems can usually be linked to one of the following anomalies:
1. Airflow off the outer edge of bug-shield (if installed).
2. On power folding mirrors the mirror may simply need to be recycled (folded and unfolded 3 times consecutively)
3. Tire/wheel that is out of balance (in this case most likely the left front).
4. Lose or broken internal mirror assembly.

 

I have not had any vibration problems.

 

I have the vibro-mirror issue....I am taking the truck to the dealer in a week or so for other items, so I'll pass on any helpful info that I may find.

 

No vibration issue here on my LTZ.

 

Mine almost makes me sick it vibrates so much. I will try the recycle the mirrors trick and see if that helps.

 

If recycling the mirror does not fix the problem have your dealer take a look at Service Bulletin Document ID# 1852141 That reads:

Condition
Some customers may comment that the left outside 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.

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.
Remove the mirror glass. Refer to Mirror Face Replacement in SI.
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).

Bend the metal spring up to increase tension engagement to the mirror housing 13 mm (1/2 in).
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.
