Just got a 03 yukon xl slt 215k on it, has a few issues prndl wasn't lighting up so i reflowed it then replaced all the bulbs with blue leds, and now im getting unknown driver and dont have key fob to change it and my abs, batt, and low fuel light are on and fuel, volts,oil pressurr and temp gauge are not working, 2nd problem is randomly goes into 4lo or auto 4wd when you start the truck up. I also repaited the grill and bumper, not a real big fan of chrome
