I keep blowing the #1 fuse on my truck that goes to the parking lights and dash lights. It seems to do it whenever it feels like it. any places to look in the wireing harness that are suspect? places it goes though the body panels? someplace it could be chaffing. It happend to me 4 times this weekend on a 26 hour trip back and forth the NC towing a trailer It happens with and without the trailer hooked up so i know it's not the trailer.

Sounds to me like a hot wire shorting to ground. Does it happen at random or after you turn something on or off? If it is random I would trace out everything that gets power from fuse 1. You will probably find something loose that touches ground and blows the fuse. If it is something that happens after you switch something on or off, then I would look at that switch.

 

it is deffinitly random...i was afraid you were going to say to trace the thing all out...that is not something i look forward to!

Check that your bumper trailer light plug isn't filled with wet dirt.

 

Check the parking lamps. Did you change any recently? Pull them all out and see if you burn a fuse with them out. Then you will have narrowed the cause.

 

Mine was doing the same thing recently, I have illuminated running boards on mine that were causing the problem. One thing someone mentioned to me was to check the cab lights for busted covers. Just my .02..

as my father has always told me, 90% of electrical issues are something aftermarket that is exposed- your trailer plug would be a great start

 

well,i tracked my issue down to the extra driving lamps. i disconnected all 4 of my extra lamps 2 in frt,, 2 in rear,turned on park lamps , no blown fuse, then started to reconnect lamps. the second lamp popped fuse. took the lamp apart, couldnt see anything wrong, re asm lamp, reconnected lamp to park lamp system, and now, no popped fuse...go figure...........

so , as someelse suggested, if popping fuse, u are grounding out somewhere.
