With the car jacked up and on safety stands, follow the wiring harness from the taillights to the front of the car. The wire is probably pinched, burned or shorted somewhere along the way. Did you have any work done on the bottom chassis area recently? Does sound like a pinched wire.
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 have a serious short circuit in the wiring to the tail lights. Fuses protect the wiring in your vehicle from catching fire. You need to trace the tail light wiring from the fuse box to the tail lights to locate the fault/short circuit. A wiring diagram can help as it shows the colour code of the wires to the tail lights. This problem can be difficult to trace and you most likely need an auto electrician to fix this problem. It could mean installing a new wire to the tail lights as a quicker fix and bypass the fault..
There is only one circuit. You have to trace the wire from the fuse to find the short. The wire runs to all of the parking and tail lamps as well as the instrument panel, thru the dimmer. If you find connectors along the way, disconnect them to find out if the short is beyond or behind the connector, using an ohmmeter.
Possible that the brake light switch shorts with the circuit, sometimes this can be a brake switch ground shorting through the dash boarrd ground circuit and turns the light on.
You need to disconnect the brake switch and trace the line. also check if the rear brake lamp circuit is shorting in the tail lamp assembly and so turns the dash /park light circuit ON.
This can happen if the tail lamp assembly /holder is shorting. So remove and check the tail lamp circuit/ the park/brake lights.
you have a short the short you have is a taillamp socket short. so youll have to inspect the tail lamp socket and acess the light. when you open the lights youll see where the lights go in they are very prone to touch together and take out the fuse.tail light socket short are common on GM and I know this is Isuzu but they use the same part.
There is a recall on the tail lights from GM. The problem I found on mine were faulty contacts that would burn out the bulb contacts in short order after replacing the bulbs. So even if you replace the bulbs they will only work for a short while before they burn out. Take it to a GM dealer to get the complete tail light assemblies replaced.
