Looked out of the windshield and saw smoke I jumped out of the car and saw where the smoke was coming from and tore the wires from the switch. I went to a ford dealer and he said it is not covered. Wrong year. This is the same switch that has caused fires that burned down homes and has caused deaths.
At approximately 2:00 a.m on july 6, 2005, my husband and 16 year old son were awaken by a neighbor, telling them that our 1994 grand marquise (mercury) was on fire. My husband and son barely escaped when the fire hit the house and burned our home down to the ground.
Vehicle was parked inside of the carport and without warning it caught on fire. Driver called the fire department to extinguish the fire. Vehicle was not towed but was inspected by engineer with verite forensic engineering contracted by ford motor co.
