Was driving along in car and exterior lights fail. Other failures include dash board lights, radio down and fuel gauge failure. Car kept running and no noticeable driving problems. Kept driving then exterior and interior faults restored. Second time this has happened in last month.
What caused this and what do I need to start trouble shooting?
Yes. Scotty answered my question directly on one of his YouTube videos.
Short answer: Check grounds and inspect BCM.
Start at 8:40

Start by checking all your fuses and grounds.
Hopefully you don’t have messed up wires, just try and look at your owners manual to see which fuse is for the lights that went out, then see if it’s blown and replace it, super cheap. Wire issues though? Not so much. So best of luck I hope it’s a fuse!!!
