I have my 1998 firebird as a daily driver but need some help. I see the guages perfectly except the mileage... At night i barely see it but i can (and seems everything works, trip counter ect) but in daytime you can see it at all. Im guessing the light behind it is blown out, and need to know how hard it is to get behind it and replace the bulb and if anyone knows what type of bulb it uses.... any help would be great!
