So I was driving home and all of a sudden when I put my blinker on, nothing happened. No dash light blinking and no tail light or front marker blinking. Then I realize (once I got home) no brake lights.

So I checked under the hood and both fuses were blown. So I replaced em today and it worked fine for about 20 min drive. Now they're blown again!!!!

Help. Where should I start?

 

you have a wire rub and your shorting to ground before the load(tail/turn lights)
look at the harness and see if you can find a spot that is not secured or crushed. on semi trucks to find the real hard ones. i hook a 12v high beam bulb up to where the fuse is suppose to go and i put my little amp clamp on the loom and keep checking different spots down the loom till i run out of amps and search carefully between my last spot with amps and the spot where i was without amps. and find my short. if you wait long enough you can just touch the hot wire but i try to avoid that

 

if you have one check your trailer plug they can get and hold water and other stuff that you dont want

 

I'll check both those.... I'm not sure what's going on. It seems like this is really all of a sudden. It's not like the truck has sat for a long time and now all of a sudden I'm driving it and it's not working. This IS my daily driver.

AHHHHHH.
