My Mondeo has deceloped a weird intermittent fault..initially there were occasions when the airbag light came on and stayed on. No flashing, just stayed on. After a while I worked out that when I started the car, if there was a delay in the blowers coming on, the airbag light would stay illuminated.

More recently it has escalated, in that the speedo, rev counter and odometer also stop working if the airbag light is on. In one instance it was around 6 miles of driving before the blowers came back on and it started working normally.

It's still intermittent - it happened this morning once, but not for the last 3 days - anyone know what this is?

It sounds like a bad connection somewhere.

I will let more experienced people suggest where to look.

Q.

Not only a bad connection but more than likely a bad earth connection as it's affecting so many items. Look for somewhere damp as this can cause electrolysis on the earth (usually seen as a white deposit) as most connections are aluminium.
