Re: My car is study blowing fuses and dont know why
Faulty wiring causes short circuits and blown fuse/s. The blown fuse in the fuse box indicates the faulty circuit and this is where you start tracing the problem.

Yea , an what would you like to know ? You have a direct short to ground on that circuit . Looking at a electrical distribution diagram to see what all that fuse powers should be your first step . Do you know how to trouble shoot a short circuit . Fuse # 26 7.5 amp powers light switch & multifunction switch . Free wiring diagrams here http://www.bbbind.com/free-tsb enter vehicle info. year , make , model an engine size . Under system click on lighting ,then under subsystem click on headlamps . Click the search button them the blue link. Study the wiring diagram ,get a DMM - digital multi-meter an test the electrical circuits . Could be anyone of these switchs , wiring etc....

Hey Kellan,
I would try to find out WHY the fuse is blowing.. but... you might try a 10 amp.. BUT NO MORE.... if the 10 amp blows right away... you MUST find out why they are blowing...
Check battery connections, ignition switch, any where the main wiring is passing through the firewall, or anywhere the harness is reduced through tight spaces...
good question
no, its really just a jumper , it cant blow out.
its there to activate the ECU flash codes, like all cars of this era.
you can study this here.
with the fuse in place the CEL lamp flashes error codes , if any.
Hi Merido, If the fuse is blowing in the center try using a fuse with a higher rating. If the fuse is blowing towards the side, you have a short circuit. If the rear lights are working correctly the problem will be between the tail lamp wiring and the number plate. look for anywhere on the harness which may be rubbing against the body of the car. It should not be too dificult to find the fault and rectify it. Regards John
you have some componet that has melted down contacts (it's hotwire is grounded) so every-time u turn on the key power is fed to direct short and the fuse blows.So look around at things that dont work.after fuse blows does motor still operate,keep it running and find out what doesnt work then check that component for melted,grounded wires...
How do you know you have a short?
Does a fuse blow continually?
Does it blow without any bulbs in all four sockets?
Does it blow with the light switch unplugged?
Just a place to start.
For me,I would have a complete wiring diagram and my VOM Meter out and study this for awhile. Think it out logically,not guess. Then test.
You owners manual will tell all the things protected by that fuse.Unplug everything the book list,put in a new fuse and if it does'nt blow then start plugging the harnesses back in an the defective part will make the fuses blow.If it blows with everything unplugged,then the problem is in you harness.Have fun!
