I've seen this discussed elsewhere, when an airbag warning light flashes a code "27" multiple times, then goes to solid until ignition is turned off. The service guy at Ford dealer says "it's a generic airbag warning, but we can fix it for about $150." I've read this appears when the passenger airbag OFF indicator lamp is burned out, which is not the case for this vehicle. If this switch (passenger airbag off) is the problem (which he speculated was a possibility), is it a dealer-only replacement, or is the switch readily available to guys like me? Naturally, no information in the Haynes manual about airbag systems. Any information from somebody who's encountered this would be greatly appreciated, as the light is a real annoyance.
