Question about 2003 Jeep Wrangler

2 Answers

I accidentally closed the electrical cord for my trailer hitch in the door and it caused my break lights and turn signals to go out. We think it grounded and blew a fuse, so we replaced the only fuse we saw that was blown. This fixed the turn signals, but not the break lights. Is it a relay issue? Is there another fuse box located someplace other than under the hood?

There is a fuse box behind your glove box that has a fuse for your break lights

Not sure if there is another fuse box on that model but have you checked the bulbs it could have shorted out the bulbs, there not that hard to take out and very inexpensive while you have the bulb out a test light is cheap you can test to see if you are getting power when the brake pedal is depressed. Another consideration is the cord damaged and only shorting out the brake light circuit.

1993 ranger supercab charging guage remains high all the time. When not started for a few days the battery will die.


Seems that you have a power drain. If you installed any electronics check to see if the wire has an open section that is bleeding the system.
Check to make sure that when the glove box closes the light in side goes off. A sprung glove door will keep the light on and will drain a battery in about 3 days.
If you put a trailer hitch on the truck make sure that the grounding is done correctly. Lighting harness to trailer, trailer to truck. A poor ground will cause the electrical leak and drain the battery if the trailer in attached for a few day, less than 3.

I have a 2002 ford expedition that has a problem with the turn signals. when you turn on the right signal it works properly, but when you turn on the left signal both signals on the back of the vehicle...


Get a wiring diagram from the Free portion of the Autozone site. It is a little work to separate the Help categories at the bottom of their Webpage.

I have heard of SOME 4-way flashers that are built into the turn stalks causing problems. The contact pins for the turn signals are shared as 4-way flasher pins. Try clicking the 4-way flashers off/on about 20 times and then use the left turn signal. It has been known to reseat the contact pins.

The wiring diagram I mentioned would show where the tailgate top light gets its power. One feed should go to the brake light switch for the brakes and another feed should be the flasher feed.

As I see it, you have 2 extra lights going on when you use the left turn signal. Those 2 lights are the tailgate light and right turn signal. The wiring diagram should show the places where the wires are close enough to cross. I am thinking the 4-way flasher is the only place where the top tailgate light gets flasher power; the rest of the time the tailgate light is a Brake light.

I do not want to spend your money on an unnecessary turnstalk and that is why I say to look at a wiring diagram and see if there is anyplace where the wires could cross.

Last, trailer hitch plug. All wires are bundled with left turn, right turn, and brake light in the trailer hitch plug. Corrosion could connect the terminals.

Would like to know what you found.

Does anybody know how to wire a towbar wiring unit to a ford escort 1999?


Wiring the vehicle for towing is fairly easy. There are a number of good wiring kits available and these should be used, rather than trying to design your own.

All trailers will need brake lights and turn signals as well as tail lights and side marker lights. Most areas require extra marker lights for overwide trailers. Also, most areas have recently required back-up lights for trailers, and most trailer manufacturers have been building trailers with back-up lights for several years.

Additionally, some Class I, most Class II and just about all Class III and IV trailers will have electric brakes. Add to this number an accessories wire, to operate trailer internal equipment or to charge the trailer's battery, and you can have as many as seven wires in the harness.

Determine the equipment on your trailer and buy the wiring kit necessary. The kit will contain all the wires needed, plus a plug adapter set which includes the female plug, mounted on the bumper or hitch, and the male plug, wired into, or plugged into the trailer harness.

When installing the kit, follow the manufacturer's instructions. The color coding of the wires is usually standard throughout the industry. One point to note: some domestic vehicles, and most imported vehicles, have separate turn signals. On most domestic vehicles, the brake lights and rear turn signals operate with the same bulb. For those vehicles without separate turn signals, you can purchase an isolation unit so that the brake lights won't blink whenever the turn signals are operated.
One, final point, the best kits are those with a spring loaded cover on the vehicle mounted socket. This cover prevents dirt and moisture from corroding the terminals. Never let the vehicle socket hang loosely; always mount it securely to the bumper or hitch.

You can check HERE details about this part for Escort and any "graphics".

Hope help.

yes it sounds like the converter is no good,the converters purpose is, when you have a trailer it uses the brake and signal on the same bulb, so if you were to step on the brake and have the left signal on, then the left brake light would turn into the signal,on your truck it has sperate lights for signal and brake, the converter converts this into one light for the trailer, so just replace the converter and everything should work fine, hope this helps.

check for signal ground,this is not a metal ground, use a test light or volt meter to see if they at plug before you plug in the trailer, you may need to rewire the trailer.

Turn signals blink on the wrong side


Your signals don't go through any computer (that is next year, HA,HA), either a connector is hooked up wrong (crossed) to the lights or the wires were worked on and not put back together correctly.
