All of a sudden my turn signal decided it would not flash to signal my turns. The light just stays on. I do not have any bulbs out, and the fuses are good. Any suggestions??

yeah the year might help, wiggle the hazard switch and see if they start working again

The trouble with my turn signal was the brain was going bad in my Trailblazer - apparently this is a common problem. Luckily the repair was covered under warranty. Thanks for your suggestion though!

This exact problem happened to me, and i couldnt figure out the problem. I created a new post, and one person posted they needed a new turn signal multifunction lever. Hope this helps.

I had the same trouble. I noticed that if I left my hazards on for more than 5 minutes, the relay contact got stuck. Luckily under warranty, but still an annoyance!
