Inspect your hazard switch. Common for the 95-97 Jimmy and Blazer's to have this issue.

In most cases when the hazard switch goes bad, you lose your brake and turn signal functions. The third brake light should still be working though since it's on a different circuit.

Here is the fix for it:

GM Hazard switch repair Kit part # 15174447 Cost= $15.00 to $17.00 at the dealership. The hazard Switch kit will come with a small tube of dialectric grease. Smear this on the entire thing before installation.

First look at your old hazard hole. You should see it broken similar to this.

Reach in with your needle nose pliers and grasp the edge of the old switch housing and pull upwards and remove.

You should now have the entire assembly out. Now simply insert your new hazard switch in hole and push down firmly.

Takes about 3 minutes. If you can't do this repair in 3 min than your should be working at the dealer!!!

Good luck and keep us posted, at times the contacts go bad and some electrical contact cleaner may fix this issue if the contacts in the switch is still good.
