Cooling fan not working properly

I have the vehicle listed above 1.5l. Runs fine, does not overheat, temperature gauge works fine, not low on water or leaking water and the relays work fine have already switched them out. For some reason when it gets to running temperature the fan kick's in like it's supposed to but after that will not shut off. runs the whole time the car does but will shut off when you shut the switch and the car off. Restart the car and again when it's supposed to come on it does just won't shut off, no idea.
