1: I think the passenger door may have actually been open... Will have to try again with it closed.
2: When it first started, there was a passenger. During the test, there was not.
3: Didn't have the car running because that's a good way to wreck it, but yes, the driver's side belt was on.
4: Driver's side retractor works fine, because I only have the problem with a passenger.
5: Will try that if the other ones fail.
Understood, and I always make sure my passenger is wearing their belt. Particularly because I think the ticket for that is up to around 100+ now...
