Live in Wisconsin, don't know if the cold has anything to do with it, but my running lights have been staying on intermittently when the car is shut off and key is removed. Problem only started a few days ago. Through operation of the switch the lights get brighter when actually put in the position for only the running lights to be turned on, and dim but remain on when switch is shut off (and car is shut off). I know there has to be a short somewhere but before I dive into the electrical system of my car I'd like to hear from anyone who has suggestions of what else might be causing it. Defective switch? Any suggestions where to look for a short? Or where to start looking for a short? Any help or insight would be appreciated.
