Sometimes the headlights flick on and off while driving. Then when the car is turned off, there is a clicking noise in the driver side dashboard that continues until it drains the battery. Also, sometimes the door locks cycle open or closed whether the car is driving or off. This has happened multiple times and caused me to replace the battery, and still I have to jump the car from time to time. This has happened several times over the past few years, but only now have I found this site to report it to.

The headlights went out on my car while driving home in a snow storm. When I took my vechile to pepboys to find out whats wrong. They said it was the lighting control module that can only be repaired at ford dealership. They also stated it was a recall on this. When I took it to ford they said their was no recall on the module. I am unable to drive my vechile, I cant get to work. Which I am in jeopardy of losing my job. If this is on recall why wont ford fix my car. It put me and my children in harms way of almost crashing trying to make it home.
