If you didn't fix why the light came on it won't go off. If you fixed the problem and disconnected the battery cables for several minutes and it came back on then you still have a problem

Either the bulb is bad or the previous owner removed it rather than fix the problem that caused it to come on and stay on.

Gotta be a connection in the wires under your Hood
