- Corroded or damaged wiring in the emergency flashers circuit.
- Faulty emergency flasher switch or relay.
- Malfunctioning body control module (BCM).
- Poor ground connections affecting circuit performance.
- Short circuits or open circuits within the wiring harness associated with the emergency flashers.
Symptoms of B17D2 Jeep
- Emergency flashers not functioning or flashing erratically.
- Turn signals may not operate correctly or may fail to illuminate.
- Warning lights on the dashboard may illuminate, indicating a fault in the electrical system.
- Difficulty in starting the vehicle due to potential BCM issues.
- Unusual clicking sounds from the relay or BCM when attempting to activate the flashers.
