Intermittent A/C, headlight, and liftgate issues after a minor collision, likely caused by wiring damage that is difficult to trace without specialized tools or diagrams.

Workarounds Described

• Using a multimeter to test voltage at pins
• Swapping relays with identical ones from other parts of the vehicle
• Disconnecting battery to reset systems

Implied Software Gaps

• Software that automatically cross-references collision impact location with known wiring pathways and suggests specific circuit tests
