Angry wipers, A/C blower, gas gauge, temp. gauge, 4X4 selector and the transmission select

Good day, I have been trying to get to the bottom of this issue and I hope somebody out there can give me some info. On my '98 Blazer all of a sudden the wipers, A/C blower, gas gauge, temp. gauge, 4X4 selector and the transmission selection indicator have stopped working. The rig is in nice shape and I have just put a fair amount of repair in to the front end, I really don't want to scrap it but I will need the blower this winter. Anybody know what's up?

Id start by checking all of the fuses.

Guess I should elaborate. I have already checked all fuses, even changed the ignition switch, somebody before me really butchered the wiring from it.
Thx for your response.

I would suggest looking over wiring schematics. It can take awile but theymay all share a common wire. Just a suggestion.

I think the schematics you should look at will be called "ground distribution circuit" should be like four pages. I have them for my 95 but nit yours.
Sorry.

The ignition switch and grounds are both good possibilities. However, all of the things that are inoperative don't use the same ground, but they may use the same feed through the ignition switch. There are 3 voltage feeds, (hot at all times) to the ignition switch: 2 red wires and 1 orange wire. They are all in the same connector at the ignition switch and feed several different circuits when the switch is turned. Each of those circuits feed separate fuses both in the underhood and the instrument fuse panels. There could be a poor or open circuit in one of those feed wires going to or from the ignition switch. You'll need to back probe each wire in the ignition switch connector, in each position, (start, run, crank, acc) to verify if this is the problem. Pay close attention to: pink, white, brown and the orange wires, yup, two orange wires, one is hot at all times, the other should be hot only in the RUN position.

For those that encounter the same issue, my problem turned out to be a broken wire under the fuse panel in the engine compartment.
