I have a 2007 ford focus and the other even the o/d off light began flashing. we have established that it only occurs when the parking lights are on and so believe it may be a short. Has anyone had a similar problem and know how to fix it? or do you know where the overdrive fuse is?? Please help if you can, i can't afford an expensive reapair and need to at least get it working long enough to trade for a new car.
