Ford F-150 - 1997-2003 :: Headlights Come On Even When Lights Are Switched To Off
Sep 7, 2013
I have a 2003 Supercrew that does not have daytime running lights/automatic lights. However, when I start my truck, there's about a 2-5 second delay, I hear a relay click and my headlights come on even when the lights are switched to off. I pulled the dash apart. There is no sensor, relay or anything. Looked under the hood, there's no hint of anything for auto headlights or daytime running lights. I don't really care too much that the lights come on by themselves, especially in broad daylight. Can I get some leads on what to chase down in order to get these lights to stop coming on automatically?

My 02 F-350, running lights and fog lights work fine but when I switch to headlights everything goes dark. Neither high beams or low beams work. Checked the light switch and its fine. Haven't found any blown fuses and headlight bulbs look fine.

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.

Bought my 1st VW 2003 4 Motion W8. Love it! Headlight problems though. It's equipped with Bi Xenon lights? Thought they were just called xenon, but not sure. Drivers side comes on when car is started, but not passenger. This is with switch off and the drl light is on. Passenger side doesn't come on when lights are switched on. But if i turn the car off and back on both headlights light up. When both lights work when turned on neither work when turned off but i believe they should be on for daytime running lights. I have noticed the drivers side light(the one that works all the time)is very white in color and the pass side which is hard to get on is blue in color. High beams work normal. Do i need to change pass bulb?

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 '93 Accord SE and am having a problem with the headlights not lighting when switched on. All other lights, etc., appear to work; the dash, running lights, etc. I have had instances where the headlights would blink on/off a couple times before staying on, but now they just do not come on at all.
When they blinked, it was both lights together, which would lead me to believe this is not an issue with poor connections (corrosion), or the switch itself, but rather wiring related. Just a guess.

I have a 2010 RX450H and recently I've noticed the inner taillights (the portion that is stuck on the boot door) fails to light up when the headlights are switched on. At times I give it a nudge and it seems to work again. I'm guessing it's a loose connector somewhere. I tried look at the boot door but couldn't figure out how to get to the taillights. Is it even worth my trouble to attempt fixing it myself or should I send it in to the dealer to have it looked it.

So I recently bought a 1997 7.3l F250. It is in fairly good condition, but it has some problems with the lights working. The turn signals and hazards all work, as do the tail lights and headlights. However, when I hit the high beam switch, the headlights cut off entirely. Also, the brake lights do not work at all. Ive checked the bulbs and since they all work Im not sure what the issue is.

I just bought a 97 Dodge Ram 1500. The Tail lights work when I just have running lights on, but don't work when I pull the light switch out far enough for the headlights to come on. Also, and probably related, the dashboard and radio lights don't work at all. I replaced the switch assembly already and that didn't fix the problem (i didn't use the supplied wiring though, only the switch). The previous owner used it to pull his boat so the rear end may have been backed into the water. The brake and reverse lights.

I just picked up an 01 F150 2wd for my daughter. I've noticed that the light up odometer has no illumination when the headlights are off, and when I turn the headlights on (to illuminate the gauges) I get just the faintest bit of light of the numbers of the odometer. It's so dim that unless it's nearly dark outside you can barely even tell it's lit up. The dimmer dial for the gauges is turned all they way up to max before the dome light comes on.
The LCD display for the odometer wouldn't use a traditional filament style bulb for light, so I'm at a loss right now.

Plain and simple. 97 F150 with factory radio and cd changer. Just wanna know what wire to cut on the factory harness to make the radio not dim when I turn on the headlights. Or is there more to it than that?

I have a 99 F150, with the 4.6, and my headlights just randomly quit. I checked all the fuses, and switched the MFS, and main headlight switch. All I have is my DRL's. I also checked for wires coming out of the plug-in on the column, but they seem good too. I'm just not sure where to go from here....

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.

Every time that I hit the brakes, the headlights flash and the horn blows for about 30 seconds. I am guessing that it has something to do with the factory alarm? I do not have a key pad. It is a 1997 F-150.

My passenger side front signal light works properly, but when I turn my hazard lights on it will not blink normally (the other 3 blink). Inside my truck when looking at my dash I see the small green blinking arrow for the left signal, but not for the right when the hazards are on. When using the signal normally, I see the small blinking green arrow for the right signal though.

99 F-150 V-6, 125,000 miles: I repaired the odometer connection on the cluster mother board! It now works great but now have no running (parking) lights and no backlights for the instrument cluster. I think (!) they were working before I pulled the cluster to fix the odometer--not sure. Fuzes are all good--I metered each with ohmmeter for continuity, and also have 12V to the right fuzes with headlite switch in Park and Head. I replaced the headlight switch with a new one but still the same problem. Have I messed up something in the cluster board or connections by soldering there? I don't know what role the cluster plays in feeding the running lites or the cluster backup lites. Stumped. What am I missing?

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'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.

Is there a way to be able to make the fog lights come on with just the park lights? Like a aftermarket switch or anything?
