Default Fuse concern

So I'm guessing I have a short blew #6 fuse and lost break and turn lights. It's a 15a, threw in a 20a and pop again so I through in a 30a. One for the fact that I need to drive 45 min home on a dark highway. But can I leave this??? From what I heard if you put a bigger amp fuse in and it draws to much you can melt your wires? Could you some input on this if in eed to bring it to dealer or leave it?

Yes it is true you will burn up the wires if you add a fuse larger than rated because the wires are rated to only handle so much amperage and if you add a fuse larger than manufacturer spec the wires will be toast by the time the large fuse pops

Yes, you have a short! Try removing the rear tail lights and checking the wiring at each. You may just have a chaffed wire there. Did you install a trailer hitch and wiring for that? If so, Check there too.

And NEVER install a larger fuse then what the circuit calls for. Not only can the wires get hot, the insulation can melt, and cause a fire.

So I went through all my fuses to make sure they were all the right sizes. And at the same time i cut the power source to my clearance lights thinking a wire got exposed. So everything is working now. But now if I leave my lights on and exit my truck it doesn't beep now? I did have the clearance lights connected to the back of my light switch so that they came on with the running/day lights.

I did over tighten a screw and crack 1 of the 5 clearance lights so it does get condensation. So that could be shortening out all them?

if it popped a 15 and then a 20 but the 30 is holding you either burned clear what was shorting or a wire is moving aroung and then touching to ground. Check any wiring added to that fuses circuit, if any. probably a place you spliced and if you used tape, get it corrected with a proper crimp splice and some heat shrink.

I solder and heat shrink all my connections. I think it's either the moisture or where I drilled holes for the clearance lights I didn't put any rubber seals. So I'm guessing either of those two.
