156 rear fog light problem.
Im having an unusual problem with my rear fog light. Sometimes when i turn on the lights on the car, the rear fog turns on with them even though I havent pressed the button to turn them on. It doesnt do it all the time but its starting to do it more and more. As soon as I press the button to turn off the rear fog it stays off and wont come on again. My 156 is an 03 preface lift with facelift interior , if that makes a difference.
Anyone any suggestions ecause its starting to bother me.
