Hey, I got another one. My kid's car died on the toll road at the Indiana/Ohio border. I took a car dolly over there and towed her home. My mechanic did not have time to look at it, as she was only going to be home for a few days. Took it to a different local shop. Big shop. Well known in the area. They diagnosed that her air conditioner compressor locked up and killed the car. So they disconnected the clutch and then the car wouldn't start. They said one of the computers died and it would be around $800 to replace. I told them I kinda doubted that diagnostic and asked to speak to the owner. He had them check it again.
Blown fuse. $8.
Car has been running fine for 6 years after that. No air, but no $800 computer, either.
