My son's '93 has twice now run down the battery, cause is radiator fan
continues to run after switching off the engine. According to the FORD
CD I have, it is controlled by the "Constant Control Relay Module",
which evidently controls other things too.
Any of you guys seen a similar problem or have experience trouble
shooting this problem?
Thanks, JRnNC

The electric cooling fan on the 93 2.3L is designed to only operate with
the ignition switch in the run position. I would therefore put the CCRM
high on the suspect list. One of the two solid state driver relays inside
the module may be stuck in the closed position...HTH

Thanks Mike! Guess we'll go after that CCRM.
