My 2000 Denali has a problem in the hazard switch on top of steering column. The Brake lights were out except the over head strip, and after investigating, found that the hazard switch when moved slightly will then allow the lites to work. So for the most part they work with a little piece of tape holding the switch to the side. The dealer says this has been a common problem, but the switch is $300 with a couple hours labor. Is it tough to remove the column to get at it, or do I just bite the bullet and have it done? I imagine the airbag is an issue.
