Okay I have a 2003 mustang gt. this morning I went out and noticed my mileage lights were still on along with the air bag light. So I blamed it on the cold weather. I got to work and turned the car off and those lights never turned off. The mileage lights have no numbers displayed but are dots, and the air bag light is dim but not off...I have no idea what's wrong? Should I try disconnecting the battery for an hour and see what happens? I need help please.
