Here's what you should do:
* Don't ignore it: This isn't something you can safely troubleshoot yourself unless you have extensive automotive electrical and airbag system experience.
* Get a diagnostic scan: The most important step is to get the car's onboard diagnostic (OBD-II) system scanned. An auto parts store (like AutoZone, Advance Auto Parts, etc.) will often do this for free. The scan will give you a diagnostic trouble code (DTC) that pinpoints the problem. Common causes include:
* Faulty sensor: A crash sensor, seat belt buckle sensor, or other sensor might be malfunctioning.
* Wiring issue: A short, break, or corroded connection in the airbag system's wiring.
* Faulty airbag control module (ACM): This is the "brain" of the airbag system. It's often expensive to replace.
* Clock spring (spiral cable): This connects the steering wheel to the airbag system. Worn-out clock springs are a common cause in older vehicles.
* Low battery voltage: A weak battery can sometimes trigger the airbag light.
* Professional repair: Once you have the DTC, take your Windstar to a qualified mechanic specializing in automotive electrical systems or a Ford dealership. They can diagnose the specific problem and repair it safely. Attempting DIY repairs on the airbag system is incredibly risky and could be dangerous.
In short: Don't drive the vehicle until the airbag light issue is resolved. Get it diagnosed and repaired by a professional. The cost of repair will vary depending on the specific problem but could range from a relatively inexpensive sensor replacement to a more significant repair involving the ACM.
