Re: 93 fan kicks on and stays on long after car is shutoff?? (jgcox6)
First, rule out an overheating problem. If this is caused by TRUE overheating, then you can replace your thermostat or check for a plugged radiator, or something along those lines.
Does this happen even when you drive a short time - so the engine's not even warmed up?
Look where the UPPER radiator hose is attached to the head. There's a sensor there (a fan swich) - unplug it while the fan is running after shutoff. If that makes the fan stop, then get a new switch.
There's 2 fan switches on your car. The one in the thermostat housing (lower radiator hose) is responsible for switching the fan while the ignition is turned on. The one at the upper radiator hose is responsible for switching after shutoff. There's a fan timer module to decide which switch controls, and to shut off the fan even if the switch is stuck closed.
Not all years of Accords have this same system, so everyone else who finds this thread has to be careful which years...
