Electrical problem 2000 wrangler.

igniton switch faulty.

a wire has to be shorting out the fuse, check all wires and make sure no metal is showing or frayed. If so wrap the wire that is showing with electrical tape to make sure no metal is touching any other wire, this would cause the short, and would pop the fuse. You may want to try a fuse with a higher breaking point as well, i.e. a 20 amp fuse.

You have not supplied sufficient information so here is one possibility.

If you replace a fuse you must use one that is the correct amperage for the circuit.

Check your owner's manual for the correct amperage fuse for the circuit concerned and make doubly sure the correct one is installed.

If it is the correct amperage for the circuit please supply more information on the problem including which fuse keeps blowing:

1. Is the fuse popping immediately you replace it in the fuse panel and switch power to the circuit or only after a period of time of operating the vehicle? For example, if it is a lighting fuse, does the new fuse blow immediately you switch on the light concerned?

2. What is the function on the vehicle that has the power cut when the fuse blows?

3. Has there been any work carried out on any part of the electrical system or on electrical components of your vehicle prior to this problem arising? If so what was done?

check to see if someone has installed a tow hitch on the rear,they would have spliced in the wiring in the rear of vehicle,thats where i find alot of corroded wire that were poorly taped.

That or the wiring to it is shorted at some point. Remove the connection at the center back of the socket and replace the fuse--if ok, replace or repair the socket. If still blows fuse, check the wire you removed for damage near any metal object.

a loose or damaged wire is causing a short circuit!
you ned to get it tested & rectified by a auto electrician ASAP!
as wiring gets very hot & can destroy your vehicle! {catch fire]

Check the Inside Fuse Box with a Flashlight for Blown Fuses. Then Check the Fuse Relay Box Under the Hood. Check the Fuses in that one to, If the Fuses are all good, Locate the Illumination, and Brake. Replace these Relays. That should get them back on, Let me know! Please Rate my Response, I need all the Help That I can Get! Thanks!

You have a Short somewhere in the Lines. Get a Voltometer from any auto parts Store and Start with the Running lights seeing as U can get to them Easier. The dash lights are on the Same fuse so start with the Easiest First. Message me back!

It sounds like one of the wires is loose or not grounded. Check your fuse box and see if some wires have come apart from under the box.

if the 3ed brake light works , rapidly move hazard switch back & forth & recheck, if they now work change turn signal switch , they are being canceled by switch
