Bringing my wife back from the store just a little while ago, outside temps mid-90s, I lost all the electric inside the truck. Fan and a/c stopped as did the speedometer. I couldn't even open the windows. Got hot inside real quick. But, it kept running, I made a turn and headed to my favorite auto fix-it shop. Caught the owner about a minute before he was closing. Smart guy. Right quick he figured out it was my ignition switch gone bad. Oddly, with the tilt steering wheel in the up position all works OK. He has ordered part, I'll be back first thing in a.m. and he will repair. Honest guy and he knows what he is doing. Bugger having stuff go bad though. Costly.
