Ford F-150 - 1997-2003 :: 1999 V6 - Headlights Turn On When Turn The Selector To Just Parking Lights
Apr 28, 2013
Just picked up a 1999 F-150 XL, 4.2L V6, 5-Speed. Spent half the day rewiring the headlights back to factory as a previous owner did a bunch of wiring that made absolutely no sense. (Foglights or KC lights?). Anyway, works great with the exception that the headlights turn on when I turn the selector to just parking lights. I removed all but the factory wires under the hood. I haven't been behind the dash yet to check the headlight switch and I was hoping to avoid doing so. A fuse or relay that may be causing the issue? I don't have a service manual yet so I haven't been able to identify all the fuses under the hood.

I have a 2001 f150 supercrew 4x4 and my headlights will not turn on and my parking lights will not turn off. I have replaced my headlight and multifunction switches and it did not fix my issue. I have auto lights and fog lights. Does not matter what position i have the light switch in the headlights do not come on. I try to go from bright to dim still no headlights. I pull the ftp still no headlights and the only way to turn off my parking lights is to disconnect the battery. This is my only ride and its really aggravating not being able to drive at night.

I'm having problems with my front marker lights. The turn signals work but when I turn on the parking lights or headlights they don't work. They only work with the turn signals. And I can't get the front side marker lights to come on. I've tried everything...

I have an electrical problem and my parking lights will not turn off. I had to pull the fuse in the power distribution box (engine compartment) to get them to turn out.
Pulled the switch in the dash (lights still work) and the switch is good so it appears I'm getting power to the circuit somewhere in the harness? Literally, when I pulled the switch out of the dash and replaced the fuse, my lights came on.
Looking for a schematic for a 1999 F350 SWB 7.3PSD? Perhaps it's a relay gone bad?

I bought a 99 f350, that already had HID's in it, i found out i was running the wrong batters (weren't 800 cold crank) I just had to replace the alternator. Ever since the new alternator when i turn on my headlights my truck shuts off. IT fried my IDM and i just put a new IDM and 2 new batteries in it today. Thinking i had fixed the problem i drove around no issues, finally i was leaving someones house and turned on my lights, and truck shuts off!!! It restarts but now im trowing a code!!!! im guessing the HIDs are wired wrong and that's why its shutting down the truck but OEM IDM from ford is 1300$!!!!! brand new one installed today,

I use to have the 95 f150 and 94 danger ranger. And I tried logging on after about a year and wouldn't let me so i started a new one, But im in a 98 f150 now with a 5.4 and 4x4. No i saw that there was a guy with the same problem as me but the thread went no where. So one night out of the blue my head lights or high beams will turn on. But everything else will. And all fuses are good and i look at the manual and there's no replays to mess with. Even though i already did. So what i had to do to get home was hot wire the passenger side bulb and i got power to both lights. So whats going on do u think it can be the switch ?. My power with started acting up a few days before this but I don't know if that has anything to do with the head lights.

I just bought a 99 Explorer v8 2wd to replace my aging aerostar and to tow my boat. I already knew it had this problem and a destroyed rear diff when I bought it, I figured this would be the easiest problem with just a new switch. I was wrong.
pulled the fuze
pulled the headlight switch
pulled the relays at: power dist. box, keyless entery/alarm?, the box under the dash
disconnected the harness from the GEM behind the dash and from the keyless entery/alarm
Lights only go out when I pull the park lamp relay. I know what you may be thinking. But no. Its still not gonna be that easy. The relay is not bad or being activated. Its just acting as a jumper from pin 4 to 3. So out comes the test light.
At the park lamp relay (without the relay in)on the relay module I get power at 1, 5, and 4. When I ground 2 with the test light, the headlight relay kickes on. Which seems normal to me by my assumption of how the system works. Which is that these relays are only for the RAP module to flash the lights by grounding the 2 pin. Anyway... I think I've narrowed it down.
According to the wiring diagrams, the 4 pin should only get power from the headlight switch and the GEM from a white/black stripe wire. With the relay in (only to jump the power)I have unplugged both the headlight switch and GEM, and the lights stay on and there is power at 4. I figured the white/black wire may have a short to 12v and I would just bypass it. Then today I can disconnect the battery, then reconnect it and the lights will stay off. Keep in mind all other relays are out and everything is unplugged. If I plug the headlight switch back in, cycle the switch, the lights will go on and off correctly, but will eventually stay on. Even after removing the head light switch.
Does the white/black wire go to anything other than the switch, GEM, or relay. It doesn't say so in the diagram but I can't figure out why its getting power intermittently. Still thinking it could be a short I did a wiggle test on the dash harness to try to get them to come on if off or off if on. Nothing.

Using alarm or turning off head lights my running lights will not turn off. I am thinking it has something to do with alarm. I unplugged headligths and dimmer switch and still stays on. Where the relay is or the alarm box is located its on a 2006 F250 4X4....

2012 F-250. As said, when I open the doors the parking lights come on. How can I disable this? Likewise can I disable the interior lights coming on when I remove the key but do not open door?

I've got a 2001 f150 supercrew 4x4 with the 4.6. I plugged in trailer lights and now I have no brake, turn signal, or hazard lights. I've checked fuses and none are blown.

1999 Buick Regal. Instrument panel lights will not come on when we turn on the headlights. The dimmer knob is turned correctly. I've checked all the appropriate fuses (I think). The radio display is also affected. The time display almost completely dims out. This even happens when the headlights come on automatically at dusk.

I have a '97 F150 and the trailer break lights and turn lights are not working. I have checked the fuses under the dash and hood and all fuses look fine. I have also tested the trailer on another vehicle and checked the wires. Trailer lights worked and wires and connections looked fine. In searching the forum I noticed a similar problem [URL] .... and it was fixed through a third fuse box that was not in the manual. I haven't been a user long enough to send e-mails, but it looks like WhipsnHorses was the one that provided the answer before.

I am working on this 97 F150 with the EOTF. It is not doing anything. When i turn the key on, no light on the dash comes on. When i operated the 4wd switch, nothing happens, no lights on the dash, no relay clicks or transfer case noise, etc. It has a new t case motor, the switch tests out good. I have researched for a while, and either find people with different symptoms or the original poster never updated with what the fix was. I am unsure where to go at this point, i am suspect of the GEM or the t case relay, but don't want to go replacing stuff without a basis for going so. Ive tested for voltage at the switch as well and it has 5 volts at pin 3.

This has been driving nuts for 2 days.... Brake lights dont work. Either pushing pedal or turning on lights. Turn signals work just fine.
Cab/cargo/3rd brake light on back of cab doesn't work either. I have checked/done the following:
- Checked Brake pedal switch for continuity. Tested fine.
- put multi meter on wiring all the way back to brake lights. No drop in voltage.
- changed bulbs. #3157 dual filament.
- positioned steering wheel all the way up and all the way down as suggested on here. No change.
- checked multi function switch (turn signal switch) for wiring issues. None found.
- kicked rear quarter panel for caveman adjustment out of frustration. No change.
What am I missing?

My 2002 F150 Screw has been giving me issues when trying to start it for the last month. Sometimes it will start sometimes it won't. When I turn the ignition on the gauges all seem normal, the theft light turns solid then goes out, but engine will turn over but not start. Sometimes it will start if I leave the ignition on for 20 seconds then pull the key and try again. (this doesn't always work). I have disconnected the battery for about 2 minutes this usually works but not always.
Sometimes it will start first time with no issues. Once the the engine fires it runs fine. Another symptom is when I shut the engine off, pull the key and open the door, the chime telling me that the key is still in the ignition sounds. (but the key is in my hand)
I put a new battery in yesterday to rule that out and because the old one seemed to be getting weak. (starting issues didn't go away). I don't want to put 300+ into a fuel pump without being sure that's the problem.

My '99 F150 is having wiring issues. It started with a left flasher being fast and the rear bulb not working. I put in new bulb and that didn't fix it. Then I realized that I also had no tail lights. The reverse lights are good and the brake lights work too.
So far I have searched for and repaired suspicious splices done by PO, added a ground wire that was cut off from the trailer wiring harness, checked every fuse that I could with an ohmmeter and I pulled the multi function switch and tested it with an ohmmeter also. It tested fine but I did find one of the female pin connectors had pulled out of the harness. I managed to get it back in and seemed to click into place alright. Somewhere over the course of all that I now have both sides of my flashers fast and still no tail lights. Good news is that I haven't broken my brake lights or reverse lights yet.
Could I have a bad flasher relay? Earlier in the process I did have my 4 way flashers working correctly and a couple times I even had the turn signals going. Now, none of the rear blinking lights work but the front ones go 90 to nothing and I still have no tail lights. My truck does have the auto lamp thing.

Well now I have to replace the multi function switch due to moving my steering wheel and the headlights sometimes working and turning signals not working. I saw a great video on youtube about changing a Multi Function Switch and it shows where the air bag needs to be removed. I was hoping that since my truck is an older 1997 F250 LD I wouldn't have to remove the airbag. Is there a way to do this w/out messing with the airbag on the 1997?

I have a 1999 ford f150 2wd 4.2l v6 manual 5 speed kk... i recently put back brake pads on it on both sides bc they were original and they were getting kinda worn down after have 184,000 on them. so after i got them replaced i put it all back together and test drove it and every time I'd go to take off my abs light would light up. strange huh? i thought so. so i brought it back home and i remembered i forgot to bleed them after i put them on so i bleed them and everything still didn't work, it kept coming on..
So I checked the FL & FR abs speed sensors cleaned them up and put them back on still didn't work. So I found the rear speed sensor mounted on the differential and took it off it was pretty nasty and had a little bit of metal fragments on it so i bought a new one and I unplugged the batter and stuck it on hooked up the battery test drove it and the light has stayed off ever since!! so if u have put new back brakes on and the light comes on check the rear speed sensor first.. real easy to install just one bolt.

The tail lights do not turn off- the head lights do not turn on. every fuse was pulled and still the tail lights stayed on. Headlight switch was swapped out with a new one to eliminate it with no different result. No modifications known to have been made to the electrical system. This thing did spend a lot of time in NY state, so corrosion is likely. But this does not explain how/why the tail lights would stay on even if the headlight switch was off... IMO this would have to be an ignition switch issue.
