The day time running light on the drivers side is staying on and wont shut off at all and I had my job look at it and it is the junction box. However I have had multiple people tell me they have had this issues.
When I turn the truck off the dim headlamps stay on with the keys out. The only way to make them go off is to pull the battery.
