1991 Ford Taurus 6 cyl Two Wheel Drive Automatic 165000 miles
My son left the lights on in his car and the battery went dead. We jump started it but got a cable on the wrong post. Since then the heater/airconditioner is either off or working at full blast/ full heat, the brake warning lights are on permanently, the rear window defogger doesn't work, and I'm sure there are one or two other little issues.
Any ideas on what happened and what we need to do.
