Anyone have issues with turn signal in mirror?

[jherbst777]

Hi guys - first post on this site but I have used it very often for reference...good stuff. Anyway - the turn signal in my passenger side mirror of my '07 Yukon Denali decided to quit on me last week. No other electrical issues. When I turn it on at night you can see that its really trying to work on the very top and very bottom of the arrow but obviously nothing like it was. It still folds in fine, operates correctly and defrost is still working. Is this a bulb issue or do I have to spend a bunch of $$$ on a new mirror? Thanks!!

Jherbst,
Have you talked to the dealer yet? You could always try and replace the light bulb and see if that was the issue. I would start at the dealer, they will at least be able to diagnose the issue for you.

Every so often both sides of mine don't work, and it coincides with the switches on the doors not lighting up. Its weird, happens maybe once a month. Always both sides at the same time.
