Need some advice. I have a 2011 Ford Edge that just recently hit 101k miles. The check charging system light kept coming on and off on Friday then while I was on my way home, I experienced a full system shut down of the electrical in the cabin. When I pulled over the engine - for lack of a better word, shuddered and seized. The steering column locked and I couldn't put it in neutral to get it in a safer spot. I thought it was the alternator so we changed that and got the same issue. Took the alternator, both new and old, to be tester and both are fine. At this time, the battery will not hold a charge, everything in the cabin is dark, and for some odd reason it's blowing hot air out of the vents full blast and can't be turned off. Obviously. We're still going to check for exposed wires and possible corrosion. Any other thoughts as to why this is happening?
I do know I have a blown fuse on the positive connection to the battery which I'm replacing tomorrow. Surely that's not the only problem.
