Get you some rin foil and put on the fuse and plug it back in. Where ever the short is. It will start smoking. So becareful and keep yours eyes open for smoke or burning. You will darn sure find the problem.

Good Luck.

Why does the fuse for my tail lights keep blowing?


It sounds as though you have a loose wiring connection somewhere.

Check your wiring in the area of both tail lights/brake lights. You're looking for corroded, loose or broken wires - and particularly a corroded/broken earth wire. Check the connectors where the wires fit together, too.

If your brake lights are built into the rear tailgate check where the wiring goes through the bodywork and into the tailgate via small holes. The wires may actually pass through rubber grommets/plugs.

Over time - in a tailgate - the wires flex and become brittle with the constant opening/closing and can break. Other than that, check the wiring in the rear light clusters

30 amp starter fuse keeps blowing on 98 cherokee


you may have a short (verify the integrity of the insulation of the positive wire from that fuse going to the rear window defroster, check the relay & switch.) try to replace the relay.

Tail lights, instrument panel lights, and license plate lights not working. Fuse blows immediately when changed.


that line on that fuse is shorted, the fuse saved the fire.
we use an ampclamp DC ammeter to find the wire that is shorted
and the actual point of short.

the park-tail circuit (tail fuse, right) is the most complex of all.
20 lamps inside car, and many out side, it is the hardest to find of all shorts. but not with the tool
first check for damage behind all park lamps
i bet the fuse blows in park (1st click) not head lights. right?
side lamps the 4 front rear park lamps, some call it tail its not really tail now, was in 1920 ,not now. park is everywhere.
but the fuses can be marked tails, for fun .
imagine, calling the 2 front lamps tails. and are on .(my on going joke)
sidelamps,
the inside lamps are many too.
all dimmable lamps. so turn the dimmer down to zero and see if fuse blows now, NO?, bingo.

the best way to fix this is , visual inspections for collision damage or wire hacks in the cab.
then the fuse is pulled and circuit breaker inserted 15amp
(they sell em)
then we connent the ammeter to the wire (output of fues)
i push the switch and amps goes to infinity and the CB trips
if follow the cables, and find what line is shorted.

i missed one problem
on the rear or front 4 corners of the car may be twist lock blubs.
like 1157 or? these love to short. push in lamps never short.well not the lamp actual.
in not sure what lamps the 06 uses, but replace the brass based lamps. (in park tail ckt)

you obviously have a short to ground on one of the wires to the back (if it was the front the brake shouldn't blow the fuse). the most common problem is usually in a trailer light harness. if you look under the drivers side rear of the truck, down under the tail light there will be a plugin junction. pull this plug-in apart and see if the fuse still blows. if it does then the problem is forward of that connector, if it doesn't then the problem is behind that plugin. be sure to check for "green death" (electrical corrosion) at all joints especially any trailer hook ups.

Windshield wiper fuse keeps blowing


Since you Disconnect the motor also renewed the switch and is still blowing the fuse ,it is obvious that you have either broken wire between the switch and the motor. Try to test the failure by means of a tester circuit. Good Luck.

Bad grounds cause weak dim lights and intermittent operation a positive circuit shorting to a metal ground causes shorts and blown fuses burnt connections. You need a wiring diagram for the circuit and need to trace the wires and look for a short. Or if there is no short in the wiring and this vehicle uses a module computer for the lighting the module could be faulty.

You are looking for a short in the wiring. Start at the rear defroster and trace the wires back toward the fuse panel. You are looking for spots where the insulation is rubbed off and the wire is bare touching the body or possibly 2 wires bared touching each other. When you find it just tape them up with electrical tape and reposition them so it doesn't happen again. Hope this helps.

Fog lights keeps blowing fuses


Obviously a short somewhere. Check sockets for corrosion, rust etc where current could be traveling across, as well as take a look at wiring into rear if you can get to it. One other thing you could try to isolate, would be to try one bulb in at a time, perhaps one will cause fuse to blow & other won't, which will give you a reference point to start looking.

Fuse keeps blowing.


First off, never bring it back to the dealer, if you dont want to waste money...
Second, what has been added to this car? new stereo, car alarm???
Were windows left open in the rain?
-If new parts were added, check the cars wiring. Most likely is short.

-if your horn and all other electrical accessories is having a problem, and wiring is good, Well what controls drawing power, and powering up these accessories? - The cars computer...

Theres no short answer for that, get a flashlight, the cars wiring diagrams, and a voltmeter - check the wires

T100 tail lights & dash light keep blowing fuses


If this vehicle has a trailer harness, that could be the problem; it could be shorted out. Additionally, if there is no trailer harness, look under the truck bed at the rear, look for a grey wiring connector that wires come out of, and run to the taillamps. I have observed corrrosion in this connector, which will result in a short circuit. You may find it necessary to cut the connector out and resplice the wires back together (eliminate the connector), if severe corrosion is indeed present.
