Are you having problems with the Gauges (Speedometer, Tach, Gas, Temp, Battery, Oil, Tranny temp) in your 03-06 (also some 07) GMC, CHEVY, PONTIAC, BUICK, CADILLAC, HUMMER, OLDSMOBILE, ISUZU (Car or Truck) where they are fluttering, sticking, reading incorrectly, or just refusing to work. Then I have the solution to take care of that for you.
