My sister in-law has a 90 Cadillac Fleetwood 4.5 V8. The cooling fans
still run after the car is shut off. So not to run the battery down she
disconnected the battery. Does anyone know why the fans still run while
Maybe a little more explanation is in order?
The circuit that runs the fans is NOT disconnected when the car is turned
So....if the coolant is hot enough to require the fans to run, turning the
ignition off will NOT stop them.
If this is the case, they should stop on their own after a minute or two.
If they do not stop after a couple of minutes, then the coolant temperature
switch is likely stuck.
The fans will not shutt off when the car is off. It ran for over three
hours and it was still on. Even after it sat for days the batter was
connected and they were still on. It sounds like the coolant temperature
switch but I am unable to find it.
