Fan won't stop. It keeps going and going and going... on 1999 Plymouth Grand Voyager

My fan won't shut off when the car is turned off? What is wrong and how do I fix it?

I wonder if the cooling fan relay has stuck shut. It is located all the way forward on the driver's front chassis leg in the engine compartment. Colors of wires at the relay are gray, dark green, black, and light green and dark blue
Thanks. Is that what the part is called?
