I have a 1999 Ford Van E-350 that has an intermittent problem: The seat belt / door ajar / lights left on / keys left in the ignition gong starts up as soon as the ignition key has been inserted into the ignition.

Checking all the possibilities, non of the above problems is found. Yet the gong continues through the entire trip.

The gong is not designed for long-term use on trips.

I tried temporarily disconnecting the sensors under the seats, but that did not stop the gong.

Any ideas on how to address the issue?

Thanks

Lar2- I believe that you will find a electrical short ,probley in the ign. Switch it self,you will have to use a test light to find out. It could also be a shorted fuse, where it's really blown but has elect. Curent flowing through it. Bnelieve me I've seen this . A good mech. Will tell you this can happen also. You will probley have to take it to a mech. Any way, I say this because I don't know how mech. Inclined you are. HOPE I've helped you though, Good Luck. :::::: F.B.E.
