Ford Ranger Lighting and Electrical Problems

  • Won't communicate with state inspection computer. Previous owner had installed light bar, which was removed but wire and toggle switch remain (were disconnected last week). The dome light often comes on or stays on, so I removed the light bulb. Battery gauge light doesn't work. Temp and battery charge gauges read zero when engine is cold, then tremble and begin to register when truck is driven for a short time. Cigarette lighter will heat but won't lock into 'down' position. I went to another shop; the guy there said that the state inspection software had been modified to close loopholes, and he couldn't bypass functions like he used to. I'm an electronics tech, and I read in the Forum to check clusters 11 and 17, cleaning and checking connections. I'm off to look at the dash gauges. Fuses are ok. Any advice? Thanks -
  • abs light has been on for awhile, brake lights stopped working a week ago. replaced brake light switch,no change,put wire in brke light switch plug in, light still wont work, the plug-in has power to it also, overhead brake light on cab has power . the turn signals and tail lights work fine, brake light wire under the cab has power but not at the brake lights . Im sorry it is a 1994 ranger 4x4 extended cab. Is the wire bad or could it be something else ? The brakes work fine .

    ABS - On a 94 (I owned one), if you let the brake fluid in the master cylinder get low, the ABS light will come on when you press on the brake.

    Brake Light - I doubt the ABS light has anything to do with the brake light. You have found power in the wire 'under the cab'. Therefore, the problem is between there and the brake bulbs. I think there is a main connector at the back of the truck where all the wires come in - brake, turn signal, and backup. This connector may be dirty or loose. If you don't have an electrical diagram, trace back from the brake bulb to this connector (Get the brake color wire), and test for brake power at the connector. This will tell if the wire is good to there. If power there, the problem is toward the bulbs. CHECK THE GROUNDS back there. It might be a ground problem.
  • Hi

    I know this information is late, but i wanted to pass on to you that I had the same problem with mine.. the problem was the "inertia" switch located under the passangers side dash... its a red button switch that is designed to cut off the fuel to the engine during an impact.. over time i beleive these things are designed to die out.... they are linked to the starting system.. if the button is pressed or i say gets old it will give out.... you can have it replaced or have it by-passed at your local pepboys ....... anyhow hope it helps........ send me a reply if this info helps or not

    thanks....
  • i have a 99 xlt. i recently had to diconnect battery to clean connections, now my wipers and power windows won't work ?
  • i've checked the fuse and cant find any that are blown

    I had a issue with the wipers first of not coming on and then the dome light would not come on and then the Windows would not roll down and the 4X4 Switch will not engage the 4X4. None of them have power to them. I used to start the truck and let it run for 15 minutes with the heater going and it seemed like it would work to get them going after the truck got 100 degrees inside. It acted like it had moisture on everything then yesterday I went out and ran the truck for a half hour to get them to work and hopefully dry everythying out but they will not work at all now. Does anyone know what the issue might be? :mad:

    thanks guys

  • i have a 98 3L 2wd i hoped in my truck recently and turned my park lights all the way on and then i had no dash lights no park lights but i had headlights. i tracked down the fuse to the powerbox under the hood i replaced the fuse it blew right away i put another in it took around a minute to blow so i got under the truck tracing the wireing wiggling it around put another fuse in it took 15 minutes to blow. so i swaped out a working relay and the fuse blew right away. another fuse in ran the truck for a few minutes blew again and i have a dim dome light after the fuse blows.my dimmer will not turn the dome light on when the door is closed either now.i also had a set of after market fog lighs i had spliced into the factory fog harness i cut the wire and the fuse is still blowing. if you have any suggestions on what could be going on i would apperciate hearing them
  • hello i have a 94 ranger v6 xlt the 1st problem with it is their is no dash lights every other light works except the dash lights and the gauge work as well, could this be head light switch problem?? what else could cause this?? also the 4 wheel drive works sometimes and sometimes it doesn't . i have repaced the electrical motor at the tans that switches it into 4wd with a used one but it is still doing it? what could this be. also the truck only has 131000 miles
  • I have a 96 ranger that i bought off a friend of my parents. He was driving it since roughly 2000 and the check engine light is always on on the dash. A friend of mine also has one from this year with the same issue. is this a flaw with rangers of this year or is it something that needs to be fixed. My mechanic looked at it and only found one code to come up and it said it was the gas cap that was making it stay on so he shut it off. The next day the light came back on. It only goes out when the battery is un hooked or the mechanic shuts it off and then it just comes back on a few days later. anyone have any ideas why it might be doing this?
  • bolivarbolivar Posts: 2,316
    Gee, you think you might have a bad gas cap?
    Or a hole in the vacumn line that goes to the gas tank?

    Or maybe if you fix it, the check engine light will stop coming on?
  • I replaced the gas cap and its still on. i also have had my mechanic look and he cant find anything else wrong.

    Did the mechanic do a smoke test on the neck? A friend of mine had this issue and when the smoke test was performed they discovered a small fracture located just below the gas cap, ergo, the new gas cap wouldn't fix it. I'm not sure how he fixed his, some type of goop I believe but I know he didn't replace the neck.
  • Battery light keeps coming on and going off,, anyone else have this problem or can tell me what to do to correct this?
  • I have a new alternator, i have a 2003 Ford ranger truck,,

    i just found a link details how to open the door panel and fix the light switch problem.

    Hi Bert,
    Thanks for the note. I disassembled the front door panel and simply unplugged the light switch from the latch. Now I need to do the same with the rear suicide doors. I think the loose switch is in the rear doors as it still does the same and if I slam the rear door it's ok. Some rainy weekend I'll tackle that one.

    My 1999 XLT 4L Ranger came with a tow package. The left signal (yellow wire in ford main wire harness) has failed. I disonnected the trailer harness plug and there is no signal. Next I disconnected the plug on the harnees that leads to the right side up near the rear frame and bumper and have a signal on the male prong.

    Following this yellow wire to the front of the truck, I untaped the harness and found a heat shrink connection on the brown wire. Moving on, after dropping the spare tire for access, I went as far as a "Y" wire connection all taped up just above the rear axle.

    From what I can tell there is no signal at this point. Fuses seem ok. Any help is appreciated.
