Why won't the parking lights shut off on a 97 GMC Jimmy?

If the parking lights on a 1997 GMC Jimmy won't shut off, it could be due to a faulty headlight switch, a malfunctioning relay, or a problem with the wiring. Additionally, a stuck or damaged parking light switch might be causing the lights to remain on. Checking these components for proper function or any signs of damage can help diagnose the issue. If necessary, consult a professional mechanic for a thorough inspection.
