First I would make sure the bulb is good. You could use your multi meter to test for continuity. If the bulb checks good, make sure the socket is good and check if it's getting power. If it isn't, you'll need to work backwards until you locate the area where there is a power loss.
If you have any questions, let me know. And, I hope this helps.
