you light does not come on when you put the key into the on position before you start the car?
do you have a sedan or a hatch?
If you own a hatch you most likely only need to replace the clock unit. @ $30. If it is not the clock, you will need to ecu/pcm that most likely needs to be programmed, but not entirely sure of that.
if you have the newer style dash, in the sedan, I believe the bulb can be replaced.
