Question about 2000 Jeep Wrangler

1 Answer

Electrical problem 2000 wrangler.

Fuse keeps popping for the running light. With the fuse out the speakers are making noise when we turn the headlights on and off and even a little with the brake pedal. With larger fuse in it the headlight switch turns the radio off when you turn the headlights on and turns it on when the headlights are off.

That means 1 of 2 things'
wrong size fuse, you never stated amps. or the color of the ATC fuse.
the correct fuse blows with any short, ending possible fire.

sounds like you have gross electical issues.
even bad battery terminals. clean them.
try a fresh charged battery
use a voltmeter and measure voltage yet.
at the battery and those things that fail?
that speaker noise is alternator whining noise, caused buy shorted diodes in same.
you do know alternator can fail in many a way.
regulates wrong
open diodes, and 1/3 loss of power
shorted diodes turns alternator in to a huge noise generator
over charges battery
to name a few and bad bearings,

I have a 2004 jeep liberty my turning signal fuse keeps burning out, but my hazard lights work. Once my fuse burns out, I have no left or right turning signals.

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.

My fuses keep popping any ideas?

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?

Our brake lights keep going out, the Stop LPS Fuse keeps popping. My husband checked wires, nothing looked wrong. He replaced the brake lamp switch and fuse still popped. Now he's checking actual tail...

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.

2000 jeep wrangler fuse keeps blowing?? What do I

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.

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.
