    Ever since i have owned my car at night the speedometer doesn't light up so i rely on my hud which is fine but id like to get this working. Everything else behind the dash lights up. Like gear position or high beams on or off. But as far as fuel levels, speed, rpms, engine temp. None of which are back lit. Has anyone ever heard of this happening? Or know how i can fix it? I have looked around and cant find anything on this.

    I looked for the fuse but i cant find which one would be just that section of the dash.. Do you know where i could get replacement bulbs? Maybe even Leds? Thanks

    Are there any write ups on taking out the dash and such to get to this area?

    all you have to do it pull the panle out and the cluster is right there with 4 nuts(screws), the knee cover thing doesnt have to come off all the way, just pull the top two clips out then the top panle and be poped off..
    sorry for the spelling

    but all the other lights work in the cluster like the headlight, turn signals. other individual lights light up. Even though its just part of it, it could still be a ground?
