maybe the fan were wired straight to power so whenever car has power the fan will kick on.

Coolant Temperature Sensor.

When the ECU gets a bad / out of range reading it 'assumes' the worst and runs the fans all the time to avoid overheating.

Please take a few pics and trace your wiring. We could probably help if we had some info.

My fans do the same ever since I installed an OBDI stepdown on my B14. I know my CTS is good.
