HUD and tach not working, need help

[Seff]

I just bought a bone stock unmolested 89 240, but the HUD and tach arent working. The tach was working for a little while, but i heard something in the cluster pop, probably a fuse, but I dont know where it is or if there even is one in the cluster. I can hear the HUD making a high pitched noise, but then it goes away, and comes back on, goes away, comes back on, etc... Every once in a while, the light will illuminate but its very rare and only stays on for like a second. Id really like to fix this one b/c it only has 114k and its really hard to find one around here. Thanks for the help in advance, I really need it.
