Hey all. My idiot lights no longer illuminate, my electric gauges no longer work and my jakebrake doesnt work. However, sometimes everything will operate correctly for about 5 miles. Ultimately my engine fan switch governs it all. I thought maybe a wire issue but bouncing has no effect. I changed the switch and no better. Sometimes it'll all start working while I sit and idle. I reached in my dash and jiggled wires around by the handfull, nothing. Since it works sporadically, it's not a fuse. Im not an electrical person. Any advice?
