my digital odometer on my 98 camaro doesnt light up... if you look very close u can kinda see it still but its not bright and yes i checked dimmer switch and it works good for the gauge lights but my odometer is not lit up...

 

bulb... thats all i can think of. not sure how many there are or how to get to em.

 

there is a bulb behind there. 194 size. probably burned out. check out the how to i have in the interior to get to it.
