Ford Ranger Lighting and Electrical Problems



  • bolivarbolivar Posts: 2,316
    The relays are usually beside or inside the fuse box under the hood. There may be 2 or 3 of these, many times they are identical. Fuel pump, power windows, etc. I would first pull all of them and clean the contacts. Then if still dead, start switching them around. If the fuel pump starts, you still don't know which one is bad, but you do know one is bad and you need to buy a new one.
  • Thanks for the information bolivar! I'll check it out.
  • On occassion my 99 Ranger XLT 4L headlights begin to flicker on startup and at idle. When I turn on the headlamps the flickering stops.

    Any ideas?

    1992 ford ranger 2.3. takes alot of cranking to start, but when it starts it runs great. check engine light comes on after starting and tach is not reading accurate. Any body else ever have the same problem?
  • Hey all,
    Today my running lights stopped working, I have low and high beams. For a day or two prior to them stop working, the running lights would flicker on vehicle start-up.

    Is this a fuse?

    Thks in advance,

    With your other message, a wild guess would be a bad headlight switch???

    Or bad multi-switch. This is the the switch on turn signal stalk. I can be used to dim your headlights, right?
  • I have a 2002 bought in the summer of 2004. Every year when it gets below around 40 in temp the voltage guage wont go over about a quarter for 10min or maybe 10 miles then it jumps to normal about half way up the guage. Had the ford house look at it, they replace alternator, later the batter all in the first year. The problem persists. This year Im driving over a hour to and from work. One day it didnt kick up and i tried to get it home knowing I was running the batter down. Got it home, replaced the alternator. Battery was still good. Problem still remained. Replaced two relays. Problem still remains. Mechanic friend bypassed all wiring from alternator to battery with additional wire. Engaged alternator immediately. Is there another relay? Could it be the wiring? I do have some internal electrical problems also like dome light staying on. Cd player and its ghost. Could it be the brain? HELP,,,IM SICK OF THIS TRUCK
  • I took to checking and replacing the relay switch (main control box under hood) for the washer pump and its is now working fine. Weird thing, before I touched the old relay I started the truck up and the running lights were working.

    Now I am confused.
  • The running lights are still flickering, when I turn on the headlights no flickering is observed and all lights (fog, high, low beams) work.

    Any suggestions?

    Are you still having the fuel gauge problem as of this date?
  • esmithesmith Posts: 13
    I have a 98 ranger that has no power at the fuel inertia switch. I have verified power at the relay, and have even jumpered the contacts with a paper clip. Still no power at the inertia switch plug. (I have the switch unplugged and expecting 12 volts on the green/yellow wire) It appears to be a severed wire but does anyone know the route that the harness takes to go from the fuel pump relay to the inertia switch and PCM? Any advise would be appreciated.
  • sending unit is made to fuel pump. u have to replace whole essembly.thats what i had to do.
  • Can someone tell me if the drl have a relay and if so where it is located?

    thank you
  • It is (past)time to replace my factory AM/FM/Cassette in my 1995 4x4 Ranger with something with a few more bells and whistles. I've got the both power leads and both grounds identified and hooked up (via Chilton's manual) but still have 16 wires unaccounted for. They don't match color code in Chilton's manual. What's worse, the colors coming out of the back of the radio and going into the harness are not the colors that end up at the speakers themselves. I've even tried tracking them with an ohm meter, no luck.

    Does anyone know what colors at the back of the stock radio end up at which speaker? Or maybe more importantly, how does one hook up the 8 speaker wires on a new AM/FM/CD/HDr to the existing wiring harness so everything works right?Thanks,
  • bolivarbolivar Posts: 2,316
    Only thing I can tell you - I owned a 1994 Ranger with the Premium Sound option. This package actually had an amp separate from the head unit.

    Since the wires leaving the head unit don't color match the wires at the speakers, I bet this is what you have.

    I think the amp is in the dash, passenger side. Not actually sure of this.

    I do remember one of my speakers cratered. I bought a pair of speakers that a local auto audio shop was trying to sell for about $100, found exact same model at Walmart for about $60. I think Crutchfield also wanted about $100 for them Don't remember what brand, some 'usual' name brand speakers.

    But I thought these would be a step up front the 'stock' speakers in my Ranger. Everyone wants to put some kind of aftermarket speakers in, and these didn't cost much, but they weren't the $20 for a pair no-name things I have seen in some places. But when replacing the blown one, I could easily see the magnet in the stock Premium speaker was about twice the size and weight of the aftermarket. I decided to see how the new one compared with the old one on the other size. With 8 years age or so on it, the orginial speaker was obviously a better sounding speaker than the replacement. I went ahead and replaced the other side just to keep them balanced.

    Sometime, stock stuff is pretty good.
  • alright so I have a 98 ford ranger. recently my headlghts stopped working. I do not have DRL. when i turn my headlight switch on my parking lights will come on but my headlamps won't. flipping my turn signal switch forward to put my brights on does not work either. but when I pull my turn signal switch back my brights do come on. My fog lights aren't working either. anyone have any ideas as to what this might be? I thought I might need to replace the headlight switch.
  • Hey recently since i had my truck broken into, i had my stereo deck ripped out of my truck. ever since then my constant power wire through the truck seems to have stoped work. cant find the reason why, but ever since this happened. i have no dash lights, everything is fine on the dash unit. gauges work, speedometer, ext. everything but the dash lights. i was wondering if anyone knows how you can fix this issue? have to stick with the truck for a few more months just wanna fix this
  • I have a 2000 ford ranger xlt. I have been having problems with the fuse that is for the wipers and speedometer burning out. what can i do to fix this issue??
  • I have a 1997 ford ranger and the interior dome light stays on all the time even when you close the doors or start the engine. Someone told me it could be the door relays but I have no idea where to find them could someone help me.
  • bolivarbolivar Posts: 2,316
    Have to take the door panels off.

    Inside there, near the actual door handle, key lock mechanism is the switch. Some people say a lot of WD40 or electrical cleaner thru the door handle hole can reach it without taking the panel off.

    I would take the panel off. THe switch might have to be replaced.
  • I had the same problem with my '02 ranger about 3 years ago. The dome light stayed on for around 10 to 15 seconds then go off, after a short while later it stayed on in increasing intervals and going to my local Ford dealer and being told it would cost $70 to look at it, I sprayed the hinges, key holes, and the part that actually holds the door closed in place on both doors with WD 40. This has actually fixed the problem, I have not had the first second of trouble with it since.
  • :sick: 2000 Ford Ranger driver side headlight and directional is dim and right side works okay and wiper will not work with headlight on
  • bolivarbolivar Posts: 2,316
    Either a short to ground (drawing current and making light dim) in the wiring before the lights, or a bad ground (not allowing current to flow thru the light) in the wiring after the lights, on that side.
  • Did you get an answer I am having the same exact problem?
  • I am having the same problem. My highbeams and turn signals work but headlight dont work. The problem began some time ago when the headlight wouldnt turn on, but when i tapped the signal switch which also turns on the high beams it popped on. So i figured it was some wiring going bad, because everything else worked and even now still works (high beams, turn signals, wipers). Anywho does anybody have a clue to what is going on and how this can be fixed? is it a easy fix? Im going to investigate at a couple auto joints and if find anything i will report back.

    I have a 99 ranger. What reason would my right hand side turn signals not work. The bulbs are fine... but only the right side does not work. Any ideas?
  • This is one answer ive heard so far, and im still checking things out. The highbeam switch/blinker/washer has gone bad. The wiring for the headlights and hig beams go through it. Obvious because when clicking it foward go highbeams to stay on they dont work, they only work when you pull the switch arm back towards you where you must hold for the lights to stay on. The part can be a little over 100$ brand new, but ive been told to go to a scrap yard and ask about that part, you could get it for like 25$. The part is easy to replace yourself.
    Take off the steering wheel neck guards and the switch is held on by 2 screws, detach the wiring and replace with new switch, and put everything back in order.

    This is only one opinion ive heard, and we may have diffrent cases, but ill let you know what total deal is with my lights soon.
  • I am trying to install a rear view camera. I need a wiring diagram for the taillight. There are three wires going to the taillight assembly, a dark green with yellow stripe a grey wire and a yellow. what wires do what?

  • bolivarbolivar Posts: 2,316
    Well, I don't have a electrical diagram, especially when you don't tell what year Ranger you are talking about.

    What you need is a mutlimeter, and pull the first connector in front of the tail lights. Put one probe of the multmeter into one of the connector and have a friend help.

    Have the friend turn on the headlight, the turn signal, and put it into reverse, and push on the brake - while you move the probe around the connectors. This will show you what wires handle what functions.

    I would think you are looking for the backup lights, to trigger the camera....

    I have a 93 ranger with headlight issues - lamps won't come on when I pull the h.l. switch out - all others do (parking, tail, etc...) - power at fuse inside engine compartment, fuse good, no power at lamp - put in new headlight switch, same problem. Lamps come on bright when you pull in the dimmer switch, but not with headlamp switch - i don't get any lights (highs or lows)
