Mines not working right now either. Usually, it's the solder connection for the light that is bad. It's a common problem for most of those lights. When I push on mine it works. Take a look at the bulb first and if it's good, resolder the connections for that bulb.
To get to it remove the bezel that wraps around the top of the dash. There are 5 screws I think along the top. When you unplug the connectors on the right side don't turn the key on or the airbag light will come on and it will have to be reset. I've got the instructions to that if it happens.
