Hey guys i signed up to share this with you. I have a 07 sierra and every time it rained or was dewey i would start my truck and it would run but i had no gauges or radio. Took it to garage numerous times about $600 later replacing fuse panels n such problem still there: moral of this story check every light on your truck headlight, taillight, 3rd brake light, fog lights if you see water in your light unplug it and order a new one! This was my issue 3rd brake light was full of water sending short back and cutting everything but motor out.. hoping this will help someone
