The high speed switch for the heater, and the stepper motor in the dash, are fire hazards in a lot of trucks after they changed the heater console to center mounted in the dash. The stepper motor melted while I was driving and started smoking out of my dash in a 95 burb I had. Fixed that and later the heater switch actually started a small elec fire on the back of the console. No replacements so I went through about 50 trucks at wrecking yards, and I literally found 2 switches that didn't show signs of melted housings. Never owned a 97+ so I can't speak for those trucks.
