Possible Causes:
* Faulty Clock Spring: This is a common culprit. The clock spring is a spiral cable located in the steering column that allows the airbag and other steering wheel controls to function. Wear and tear can cause intermittent electrical issues leading to the light flickering.
* Faulty Airbag Control Module (ACM): The ACM is the "brain" of the airbag system. Internal failures can cause intermittent problems and trigger the warning light. This is often a more expensive repair.
* Faulty Sensor: Various sensors within the airbag system (like seatbelt tension sensors, impact sensors, etc.) can malfunction and trigger the light.
* Wiring Issues: Damaged, corroded, or loose wiring anywhere in the airbag system can cause intermittent problems. This is often due to wear and tear, especially in older vehicles.
* Low Battery Voltage: A low battery can sometimes cause intermittent electrical glitches that affect the airbag system.
* Loose Connector: A connector that's not fully seated can cause an intermittent connection.
What to Do:
1. Don't Ignore It: Driving with an intermittent airbag light is risky. Get it checked as soon as possible.
2. OBD-II Scan: Take your Durango to an auto parts store (like AutoZone, Advance Auto Parts, etc.) and have them perform a free OBD-II scan. This will retrieve any diagnostic trouble codes (DTCs) stored by the vehicle's computer. The codes will help pinpoint the problem.
3. Professional Diagnosis: Based on the OBD-II scan results, you'll likely need to take your vehicle to a qualified mechanic or Dodge dealership for a proper diagnosis. The airbag system is complex, and improper repairs can be dangerous. They'll have the tools and expertise to properly diagnose and repair the issue.
4. Repair: The repair will depend on the cause identified by the diagnosis. It could range from a simple connector repair to replacing the clock spring, a sensor, the ACM, or even extensive wiring repairs.
Important Note: Never attempt to repair the airbag system yourself unless you are a highly trained professional with the proper safety equipment. Airbags contain explosives and can be extremely dangerous if mishandled.
In short, get your Durango checked out promptly to ensure the safety of yourself and your passengers. An intermittent airbag light is not something to take lightly.
