Greetings,

Anyone every have any trouble with a flashing seatbelt light? The sb light on my 83 300 cd will come on randomly, stay on for about five seconds and go off. It also will come on if I use the blinkers, power windows, push buttons on for the AC controls, power sunroof. Also if I should hit a bump on the road the light come on. I know there is has to be an electrical short somewhere. Any suggestions on where or how to start tracing this short? Thanks.....

I to had this problem. I fixed mine by looking under the drivers seat for a black cord. This cord sits in its own plastic housing. The cord was out of its housing on mine and it was just a simple matter of snapping it back into its housing. The light flashes because once the cord was out of its housing it would disconnect sometimes and cause the light to come on. Sorry for not having a technical answer with technical terms but take it for what it is worth.

LoveLEE143,

I checked out the black cord as you discribed. It is connected and in its housing. I was hoping for a simple fix. I will begin tracing for electrical shorts this weekend. Thanks for info, it gives me a starting place.
