Ford F-Series Electrical and Lighting Problems

Comments

  • I have recently been experiencing some issue's with my 03 F250 powerstroke. This past weekend it started having some electrical problems. First the radio goes out, then all of the guages go to zero including the speedometer. At this point the battery light usually flickers and then all of the guages cycle a couple of times. At this point the radio comes back on and the guages go back to normal. This usually occurs while coasting or at low rpm's. I have also been seeing the battery light come on occasionally with no immediate problems. The battery light issue usually occurs either a couple minutes before or after the other electrical issue. Does anyone have any suggestions for a possible fix? I would appreciate any input.
  • I have a 2001 F150 Supercrew. The moon roof, map lights and power windows do not work. I found what appear to be a 30 AMP fuse in the fuse box under the hood, but it is metal and is the metal fuse looking device in the panel. I tried a plastic 30 Amp fuse but it did not help. The manual
    says this outlet (with the metal fuse) is only used on a Supercrew.

    Is this something I will have to get from a dealer ?

    Does this appear to be a realistic identification of the issue ?

    Thanks

  • I am thinking of buying a '05 f350 diesel, that is a lease back from an oilfield company. The problem that I have is, instead of saying 64,323KM, as the dealership claims it has for mileage, the digital odometer reads 064323KM. The 0 at the beginning of the line has me worried. I have looked at about 8 other similar trucks, and none of them has the 0 in front.
    Is there a way to tell if this odometer has been tampered with? ANY help anyone could offer would be greatly appreciated.
  • Hey Guys, this is the first time I've ever joined an online discussion...here's my situation:

    1992 F150 5.8L with towing pkg, CB, air horn, plus power everything.

    Just bught the truck wih original 60,000 miles, mostly highway. For the past couple of years (don't really know how long) previous owner hardly ran it, just started her up and let her run for 30 mins or so once a week.

    I've put about 5,000 miles on her since May, and now she's draining the battery. I've narrowed the problem down to the voltage regulator.

    Those 5,000 miles were the beak-in; I'm likely only going to drive her a couple times per week, for maybe 20-40 mins each time, and then 2 or 3 times a year for 200-400 mile camping trips.

    Question: Is this limited operation likely to bring on more/other issues with the charging system? If so, maybe I should replace the alternator or consider some other alternatives to head off potential issues?

    Thanks for any advice,
    shep
  • OK I have a '92 F150 5.8L which has an elusive battery drain. Here's the situation:
    I'd been on some very rough roads, probably driving too fast. When I stopped to set up camp and shut off the ignition, the truck died. No response whatsoever when I turned the key.

    Got lucky and found a guy who sold me a battery, truck started. I was out for a few more days and had no problems. When I got home and didn't run it for 2 days it again would not start--again, no response at all.

    I replaced the battery and starter (just for good measure) and she started right up. The next day, completely dead. Rechecked my starter installation--all good--recharged the battery and she started right up. Next day, dead again.

    I recharged and retested the battery--it held charge when it was not hooked up--and when I put both cables back on the voltage dropped rapidly (30 secs) to about 6.5V. When I pulled either cable off it steadily recharged itself. Both cables hooked up, rapid drain; either cable alone and no problem.

    I unhooked the voltage regulator harness and the drain stopped, so I replaced it. With the new one installed, rapid drain AGAIN!

    I hooked up my multimeter between the POS post and cable and then the NEG post and cable, each time pulled every fuse and relay, but turned up nothing.
    (In line on the NEG side, though, with each fuse pulled I got a minimal jump in voltage--after I pulled and replaced them all the total voltage jump was .3V)

    So I checked continuity across the tops of every fuse. The EEC relay (diode) showed resistance of .18. The maxi20 fuse associated with fuel pump relay showed resistance of .01, so I replaced the relay and got continuity.

    Still the battery drains. I am stumped. Can anyone out there give me a CLUE??

    Thanks,
    Shep
  • Hello my name is Hughett, I have a 2005 F150, XLT 54. Triton. A week ago when I stopped at the light my truck just shut off. Although I had a new battery, I had to replaced the battery. Then two days ago after getting into my truck I tried to roll down the driver side front window, but the whole window just dropped between the door and panel. Now the drivers side controls will roll the other windows down but will not roll them back up??????? where there any recalls on the electrical system on the 2005 F150 that I should know about? Help please!!!!!!!!
    Hughett :cry: :sick: :mad: :surprise:
  • Sounds like a parisitic draw. You can only check for that with an external probe on computer controled vehicles just for info. Here is what you can do though. Disconect the battery and then disconect the "B" terminal that is conected to the Alternator. That is the big 8 guage cable leading to the positive post from the alternator. Put something over it so when you reconect the battery it doesn't short to ground. Reconect the battery and see if the drain is still there. If the drain is gone your most likely cause is a shorted alternator. And yes I have come across alternators that charge the vehicle, but have a parisitic draw due to a defect. From what you described on the voltage drop when the battery is connected, it is a big short. If your positive cable is touching ground somewhere, that would cause it too, but most likely would melt at that area. Suspect your alternater!!
  • My 1999 F-150 has three adjusters per headlight, and only two of those are "adjustable". The third seems to be factory-set.

    My lower adjusters are seized because of rust on the adjuster metal screw thread. I've done the usual WD-40 soak but still can't move the screw in the threaded plastic hub of the adjuster, and at least one of the hubs already has a crack running along its length.

    Does anyone know of a source for buying these adjuster assemblies? I'm afraid Ford will want a big price for them. I've tried eBay and searched the Internet with Google with no luck.

    I went to a local car junk yard and I studied eBay for headlight adjusters, but it seems they are not sold separately from the headlights, and the headlight assemblies aren't selling for much less than $30 each.

    I spent some time yesterday spraying the two seized adjusters with WD-40 then tapping them with a small hammer hoping to loosen the plastic rider on the rusted threads, but no luck.

    Then I turned one of the seized riders as forcefully as I dared, and it began to move on the threads. That rider was the one what had a crack running its length, parallel with the threads.

    This morning I got out my utility knife and cut the rider on the other seized adjuster until it was all the way through the hub and now that one moves on the threads, too.

    It is a destructive solution, but is seems to solve my problem, and hopefully will save me about $60!
  • The wires are on the left side under the hood in the corner at the fire wall.
    They are usually taped to another set of wires.
    There will be 4 of them all together.
    I have an 05 but I cannot find the ones under the dash to plug into the switches.
    Where are they?
  • I have a 2004 F150, when it gets cold out the truck needs to warm up for at least 15 min. before the directionals will work. What would the cause of this be?
  • While pulling a trailer with my 2003 F250 Super Duty, the right turn signal and stop light on the trailer does not work, however the truck lights work just fine. It does not matter which trailer I pull they all act the same. I understand there are separate relays for the trailer lights but I cannot find their location.
  • Since the lights work on your truck and left sides of trailer only. You didn't mentioned if the tail light works on right side. If wired correctly, check the conection of the green wire in you truck trailer harness for power with test light when brake or turn is on. If no power, then it is not connected to the circuit anymore on your truck. Resplice into truck harness for brake/turn right side(should be green wire in truck harness. Looking under the truck you will see where the trailer harness goes into the truck harness.

  • i have a 2001 f250 super duty pick up and the dash doesn't work, they used to work then one day i went to use my truck and nothing worked. no fuel gauge, speed o meter, rpm gauge, nothing works, i checked all the fuses all are fine, i tried to move the connection to the dash still nothing. and ideas?
  • my door open indicator light has been staying on more and more lately. On several occassions my battery has been dead because dome light was left on. I took bulb out of dome light.... but now notice the light on the back of the cab is on. I have looked for the switch on door frame to see if I could work the corosion out of it - I can not find it - this is a three door model. Does anyone know where the switch is located or how I can disable the door open indicator. I can live without dome light. I also have a problem with the key in ignition warning ding ding ding going off even when the doors are closed (I live in an area where leaving keys in vehicle is norm)

    I have an F-150 (2000). It seems to have a mind of its own. Infrequently the wipers just start to operate. Typically they will make 2 - 3 passes then quit. This happens about once in 500 to 1000 miles. I can live with this but....

    Last night after when stopping the truck and turning the key off, the heater fan stayed on, So did the light of the direction and thermometer. I tapped the switch by the thermometer and turned off the heater, the fan stopped. This morning the battery was too weak to start the truck. It's been cold and maybe the battery is bad. (?)

    I too have had the situation with the dome light staying on. I'm going to try the WD40 and hope it works for me too.

    Any ideas why the electrical system seems to have a mind of its own?

    my voltage meter keep bouncing around, and my motor doesn't sound right. whats going on with my '92 F-150 I-6 300?
  • texstaxitexstaxi Posts: 2
    I have replaced my alternator 3 times. The voltage is up and down and very unstable. The lights(all) headlights, dome and dash are pulsating like a police car. They see no humor in this. I have looked for broken wires , corroded harnesses, bad grounds etc. but have had no luck. This 3rd alt. was overcharging but now it isn't charging at all. Anybody had the same or similar problem?

    I have a 2000 F-150 on which the odometer/trip meter digital display is intermittent. It is on most of the time, but sometimes goes out for a few minutes. It will usually come back on by itself after a few minutes, or a slight tap on the instrument panel will usually make it come back on. Both the odometer and trip meter appear to count normally. All the other instruments in the panel work fine. Does anyone know if fixing this will require replacing the whole instrument cluster, or if there is a seperate connection or circuit board for the odometer display?

    Thanks,
    Scott
  • This is a very common problem with 1999-2000 F-150's. The dealer charges several hundred dollars to replace instrument cluster circuit board. Fortunately it is fairly easy to fix yourself. Links below to a couple of "how to's".

  • I have a Ford F150 Platinum. Everything was working fine, until my electric tilt, electric foot pedal adjustments, and my power seat would not work. When you puch the buttons, you can hear the relay clicking under the seat. Went back to Ford and they said they replaced a fuse that was bad behind the glove box.(not accessible to regular people). They fixed it and it happened again about 1 week later. Same symptoms. Going back to dealer tommorrow. Any ideas whats wrong?
  • Both turnsignals frotn and back do not flash unless I continuously flip up and down, and only while I press on my breaks. Fuses in the dash and under the hood are good and the emergancy lights work fine. Any Ideas? :confuse:

    My headlights went out suddenly. I replaced the switch and this didn't help. I replaced the voltage regulator, and lights and there is still not enough juice.

    Check the flasher itself... it's usually on the backside of the fuse panel under the dash. Swap in a new one (very inexpensive) and see if that cures it.

    hi, i am having the same issue and tried the plastic 30 amp fuse also and it did not work. I was wanting to know if you figured out your problems yet because i am confuzed on this one. thanks tom

    Regarding msg #30.I had the exact same thing happen while driving my friends '08 ford f350 while pulling an empty horse trailer. As soon as you lift your foot off the gas pedal the shake stops. The speeds are only around 45 mph and as you start to accelerate past that point the shake increases. Please tell me there is an easy fix for this problem??
