there is a thermo switch on the radiator. if this goes bad it will sense false heat and run the fans. If i remember, its a 22 dollar switch.

Put the relay back in.
pull the plug off the fan switch.
If the fans stop then you most likely have a bad radiator fan switch.
If it stays on then you most likely have a bad fan relay.

Good Luck,
