Disconnect the battery and fully charge it. The number of flashes does
reveal a coded fault message but it usually stems from low battery rather than actually faulty airbag.

Battery is only a year old. another thing that happened, would not
turn over tonight and appears to be the igition switch. figure maybe it was not making contact and the air bag ckt was reseting. thanks.

Cleaning the switch seems to have taken care of the issue. has turned
over and started up every time since and no issue with the air bag light or the wipers. thanks for all the information.

Glad to hear that it was an inexpensive fix! Too often, those type of repairs cost lots of MSUs (Miata Spending Units). Iva & Vixen 2004 Classic Red No more winkin' Miata |
