Alright, so I've had a problem with my gauges blowing the meter fuse, sometimes they would work and not blow, other times they would, I thought I looked over the wiring enough and they seemed fine, so I put it back together and turned it back on and now they all worked. The thing is now my windshield wipers and washers don't work, and I know for a fact that they worked back when my gauges weren't working.

I'm at a loss, I don't know what it could be, they go to completely separate relays, and I checked both relays behind the fuse box and they're both good, but I can't get them both to work at once.

Any advice?

Did you forget to plug in the windshield washer stalk?

The only thing you can really do/should really do now is to just bust out the multimeter & reference the wiring diagram from the FSM.

I know, it's a *****, but that's probably going to be your best bet since your issue seems like something shorts out somewhere - just gotta find the offending wire.

yeah, I've already traced the route for both and am going to check where they lead soon. I know for sure that the short for the meter fuse is somewhere in between one side of the fuse, and I believe the ignition relay. Because there's continuity between the other side of the fuse and the green meter wire.

Is there any way to make room to get to the harness behind the fuse box? the harness is gigantic and I don't have room to finger through the wires and find the ones that connect to the meter fuses. I've already taken the dash and all the interior panels and carpet off.

Don't quote me, but I believe the fuse box is held in by some bolts. I never had to take mine out, but I know other ppl have.
