I have a 2008 GT with anti-theft and after market remote start. I don't know if they have anything to do with this. But, anybody have this problem? My fog lights will just go on sometimes in the garage. My wife told me this one day and I thought she was dreaming. I saw it myself today while just walking by my car. The fog lights went on, then after a bit went off. After awhile I thought maybe the anti-theft stuff, so I bumped the car, nothing.
Why me

 

Can't say on the 08, but on the 05s & 06s the key has to be on for the fog lamps to work.

 

I've had issues with one of the front turn signal/marker lamps coming on as well as one of the brake lights. When the brake light decided to stay on constantly one of my headlights decided not to function on the low setting. It was only one of the brake/turn signal bulbs that stayed lit up.

Both times the bulbs stayed lit while the key was off and the light switch was off. I had to disconnect the battery and let it set in order to correct the situation. Of course the dealer won't do anything since they can't get it to do it again.

 

I would definately call the dealer. It may be an issue with the SJB.

 

What is the "SJB"?

 

"smart junction box"

This could also be related to your aftermarket remote start.

 

Thanks, I learned that today. Went by both Ford and Sterio shop. No answers yet. But will keep checking. I do notice my fogs go on like they are supposed to with stock fob, and not at all now with aftermartet remote.
This all worked fine on my 06 GT.
