1998 Grand Marquis Cooling Fan Relay

I have a 98 Grand Marquis with a number of electrical problems. Yesterday I drove the car for about 1/2 hour and when I shut off the engine, I noticed that the cooling fan was still running. I did'nt think much of it but an hour later the stupid fan was still running. It eventually killed the battery. I jump started the car and got it running. The fan started up again. I tried pulling the fan fuze and the fan relay and the fan still was running. I discovered two more relays that are not marked in the owners manual and tapped on one of them and then the fan stopped. The relay is a F80B-14B192 -AA which is different than all of the other relays. Anyone have any experience with this problem? I think that it is odd that when I pull ou the 30 A fuze and the relay that is indicated as being the fan relay, the fan doesn't stop.

Maybe that fuse supplies power to the relay coil, but not the contacts?

You probably have the old Ford problem of a stuck relay. The contacts get stuck closed and are held in place even though the Computer shuts off power to the coil. A new relay will resolve the problem. Fred
