I'm in the far end of a road trip, and towards the end of the road trip my seat belt warning started going off erratically. Tapping on the driver side seat belt buckle seemed to silence the warning for a while. This seems to suggest a contact issue somewhere in the buckle. The car is a 2010 Ford Mondeo station wagon.
The alarm is annoying, but the real issue here is that this problem might also affect the airbag function, so I'd prefer to get the issue fixed before the return trip.
Is there a way for an amateur to fix this, or at least silence the seat belt alarm for the return trip? I have a largish collection of tools at hand, but specialized automotive tools probably aren't included.
