Ok I got a question for ya concerning my 2000 Ford Mustang car. My car was running fine, I have had no problems out of it until I had to Jump start a Ford F150 Truck with it one day and then the next day when I went to leave in my car I realized I didn't have any heat period, so then a couple days later I went to leave in my car went to start it and it wouldn't start and or it wouldn't even turn over, not even a click either!! Does anyone have any ideas of what it could be?
