Fasten Seat Belt

Has anyone had this problem? Every time I stop at a light or stop sign, upon accelerating from a stop the fasten seat belt warning lights up for a few seconds. Sometimes (especially at night) it gets to be annoying.

Louis,

On the 87 carrera the seat belt warning light is controled by the seat belt warning module/relay that is located in the front trunk area, left sides just behind the gas hood strut. Most likely you have a loose contact in the relay or the seat switch that is triggering the relay to turn the light on, or a bad ground connection of which there are three located in the front Trunk. I would check and clean my ground connections first, if there are good I would go to the relay next, pull it out and shake it, if you hear someting rattling around then it is most likley the problem. The relay is tied into the power windows and the intenisve washer system, so if you leave it out those systems will not operate. However the european vehicles do not use the seat belt warning system so you can confirure your car to not use this feture by removing the relay and installing two jump wires in the socket. The first jump wire will go between terminals "L" and "G" and the next wire will jump terminals "86" and "31"..... Hope this helps

PS: one last thing; it is also possible that the seat belt warning switch is also defective ethier wy deactivating the system will solve you issue, if you need my help shoot me an email and I will see what I can do
