My heat is acting up, my bilidge pump switch wont come on, court and limo lighting wont come.on. My nav back light comes on but not the front lights, when I toggle the nav up.the fues gets super hot and burns the fues, the dash lights are super dim, one more thing I saw was my oil preasure gauge would move all the way when I toggled it up on the nav lights. The fues panel looked corroded so I cleaned it up but still.nothing once in a while the other switches would come back on

Clean your battery connections.

i figured it out, my fues block was junk, and when the guy put the rub rail on he drilled through the wire so i have run a new wire for the front nav lights

Good find. Glad to hear you figured it out.
