Trying to figure out my buddies truck, he took it to the dealer and they put a new BCM in to fix the problem, but it still does it. Heres what it does. Randomly. Battery gauge dies, all other gauges work, no dash lights, power front windows work, rears don't,moon roof doesn't work, radio goes into lock mode, power seats work, but presets don't, steering wheel controls don't work, auto headlights don't work, 4wd indicator doesn't work. This is driving us nuts, happens all the time for apparently no reason, wet/dry doesn't matter. It always does it all together. Thanks!
