My appologies for yelling. Double-posting is not taboo, and will get maximum exposure, but it can also be counter-productive, like trying to listen to two simultaneous conversations.

You said that your relay is not receiving power at times. That said, I don't think it will be your fuse strip, since if the fuse melts the relay will still continue to function, the coil will energize and the contacts will close, there just will be no 12V applied to the GPs since the fuse is open.

Sorry, I don't have a wiring diagram for that series automobile.

Best Regards,
