    Hey guys, hopped in my truck tonight, started it up and while I was sitting there I unplugged my sander controller and was tucking the wiring back up under the dash when all of a sudden "Service 4x4" and "Service Tire Monitor System" came up on the dash. Then I noticed my fog lights, dash brightness switch, steering wheel controls, and the back lighting for my light, fog, and 4x4 switches all stopped working... Any ideas? I checked all my fuses and they all seemed fine?
