September 2003 CrashInjury

I was going down the highway. I stopped at a gas station for a cup of coffee with my sister and 3 year old daughter. When I went to put my daughter in the car I noticed smoke coming up from under the plastic part in the back seat on the door part. I saw something spark and took the casing off and then it sparked again and it flamed some everytime I blow it out it would spark again. I got the wires off the metal from the door and the one wire came apart.
