Electrical problem please help...
 

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.
