on this 98 s70, all of the gages quit a few days ago, and at that same time several warning lights came on. after a few days of doing this, i went through the fuse box, pulling every fuse, inspecting it, and putting it back. none were blown. after this, the gages all began working normally, and the warning lights all turned off.
is this most likely to be
1) a poor connection at a fuse
2) a poor connection at the instrument cluster that just coincidentally corrected itself at the same time i checked the fuses
3) a computer problem that was reset/corrected when i pulled the corresponding fuse for a few seconds, or
4) something i haven't thought of
thanks in advance for any help!
