So last night on my 2 hour drive home I was in the interstate when I start to realize if I tapped my brakes the entire dash/infotainment system would flicker, if i activated the turn signal for either direction it would do the same.
now here's the big part, if I activate the high beams in either direction on the column, my dash and stereo would black out for about 2 seconds, while the door locks all unlock and lock, it cancels the cruise control, locks the steering wheel, appears to throw the truck into neutral, and flashes a multitude of lights on the dash, including the traction control, abs, stabilitrac, and airbag lights.
I've done some reading and unplugged and replugged the BCM and it fixed it until this morningmorning it did it again, after shutting the truck off and turning back on ut appears to have went away.
what could be causing this?
