“1994 Mercury grand Marquis. The cruise control switch. My brake lights stopped working. A nice man pulled up next to me and told me my brake lights are out. I went home popped the hood of the car and started looking for a bad fuse. I found it in the car compartment not under the hood. 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. …”
