WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The headlamp switch is supplied battery voltage through circuit 195 (TN/WH). When the headlamp switch is turned to the PARKING LAMPS ON position, the headlamp switch supplies voltage to circuit 14 (BN), which then supplies voltage to the exterior lamps.
Possible Causes
- Circuit 14 (BN) short to voltage
- Headlamp switch
- Vehicle security module (VSM)
