Park lamps stay on

The problem may lie in your multifunction switch (headlamp switch) or your insturment cluster. This is a smart cluster and used to control many Body Control Module (BCM) functions. The Park lamp illumination feed comes from the Instrument Cluster (BCM) based on inputs from the Multifunction Switch. Because the Multifunction Switch is a mechanical part, used frequently, I would suggest replacing it first. Multifunction Switch Without Fog Lamp 5019711AA $114.00. (Includes Headlamp Dimmer, Turn Signal And Wiper Switch). With Fog Lamp 5019712AA $153.60. Includes Headlamp Dimmer, Turn Signal And Wiper Switch.
