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.
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.
