1999 Navara popping fuses

I had this problem in my GQ Patrol (now departed). Turned out to be some moisture in the tail light housing. Dried it out, sealed with silicon and problem was fixed till the day I sold it. Maybe your's is something as simple.

Check the trailer plug at the rear. Usually there is moisture in it or a broken wire that is earthing out. Could even be the wires that go to the trailer plug.

Cheers Matt

Hi Ron,

I've had the same problem on a work Rodeo, It turned out to be a faulty earth in the tail light due to the deterioration of one of those useless scotch-clips that had been used on the vehicle for joining the trailer plug wires onto the rear light assemblies.

freaky hey?
i had the same issue on my same year same spec navara
i had one issue with the factory bullbar park lights being rusted out and i eventually replaced the whole park lamp assemblies with a tjm setup as the lamps had better water repelling qualities.
then on a seperate matter my rear bar got the number plate lamp broken by the mrs and when i put a new one on the screw was too long and was earthing a postive lead behind the mount!!!!!!!!
scary had to be rewired back to the tail lights as it melted the wires. eventually the fuse smoked then broke!
will not use cheap fuses from $2 shop ever again.
hope this helps
i miss my navara

ALL FIXED N GOOD AND I"M A HAPPY CAMPER AGAIN!

After seperating and eliminating rear of ute entirely by disconnecting rear harness, and still poppin fuse.

I knew it had to be in main body area, just finding it.

Trawled net, and found a top top site with free d/lable manuals,(wont quote incase of any copyright issues but email me if you want it) where i got a 1998 frontier, which was the USA equivelant of Nav.

very hard, but with the diagram printed, after sifting thru 120 pages, found the main harness earth points which looked like put in at new and not grounded too good.

The screws were in a painted area, I didnt rub back but wire wooled the bolt shaft that enters chassis hole and head of bolt that holds the earth on. also cleaned earth up both sides.

Re-assembled after some general cleaning up n blowing out, and switched on..... all ok.

.... but been here before, sat for 10mins all ok.

Then I took fuse out and reduced it.

Original was a 10a, which blew, during fault finding I used a 20a (if its a short it will still go quick, as it did) now I put a 5A in and its holding fine on that so I'll call that one fixed.

Phew..... an I coulda bin fishin!!!

still saved an exy trip to auto elecs, and now have manual too!
