How much does it cost to fix the wiring connecting to my headlight?

Hello, Diagnostics may take a moment since there is an open circuit, but likely the technician will recommend replacing the 'pigtail' (the wires and connector for that headlight) to eliminate the problem. Before you take it in for service, see if the ground cable (bolted to chassis) near the headlight is properly grounded, and then wiggle wires one at a time until you find the bad spot. That can save you diagnostic time and money. Let me know if you have more questions.
