Use a voltmeter or test light to isolate the problem. Connect a long wire to the negative lead and a good frame ground or negative battery post because you could have a open ground which will cause 12V on the ground side of the light.
I'd start at the switch. If you don't have 12V on the switch load side then the problem is upstream, otherwise it's downstream including a ground problem.
A voltmeter even a $10 one from HF is your friend.
