1998 dodge neon speedo quit working if you hit the dashboard sometimes it will work for a few minutes also fuel gauge went up and down and quit working but now it is back working?

This is a problem with some Neons. There is a block of wires (controller/bus) where most of the dashboard wiring connects. This "block" of wiring overheats and shorts out. It is not an uncommon problem with Neons. Some times lifting the dashboard will "unshort" the block. You may want to try to put a heat sync on it or try some other cooling method ASAP as this problem tends to get worse as time goes on.
