Ross, Thanks for your input! It's on the right track. I'm not just talking about Goblin's and Cobalts. All newer cars have BCM or similar electronic "ocotopi" in the middle of their function! *****DANGER, Rant Ahead, Do Not Read!***** I had my brand new RV's (chassis) BCM(a 2022 F5500) took out some headlights, running lights and reduced engine output. Cause? the 40 amp BCM feed circuit's fuse was loose! That held us hostage for a week!; until a renegade electrical guru and great friend stumbled onto the problem by isolating what fed the systems that were off. (Dealer was no help, they said "put it in line and we'll look at/diagnose it in 3 weeks, then put in line for repair. Short story, est to be back on the road in 6 weeks or so and the unit was brand new. {Did I mention we live full time in this unit? This was unacceptable. This Machine had 1500 miles on it and cost $225K!} I was in a world of Pissed Off I'd never even imagined, much less visited!) ***** But amazingly everybody lived happily ever after; for a while. I don't trust BCM's.
