Head light will no dim and no signal lights

I replaced the factory headlights with aftermarket led bulbs. The left light wasn't working. They told me that the bcm computer was shot and it was going to cost 4000$ to fix. So can the bcm get fried by replacing the headlights with aftermarket led bulbs? And is there a fuse for the headlights.

The passenger side headlights comes on when battery is connected

I'd be driving at night and my headlights would flash on and off every now and then, and I've even replaced the radio and it still acts like there's a short in it and both go out at the same time

The headlamp does not come on anymore and the fuse is good

Has no power on left side

The headlight stay on , battery goes dead. Looking for possible reasons. Bad switch, bad relay, not sure where to start.

Headlights not working when lights turned on

The headlights and the rear lights don't work, only the brake light works.

2004 F-150 Lariat when using turn signals head lamps go off. Turn off turn signal switch head lamps go back on.

When I turn off my lights by the light switch, they won’t don’t turn off

Blower motor and they stop working.

The headlights will not turn off no matter what running my battery down

Headlights on when not turned on and no tail lights when headlights are on. Directionals working fine

No power going to fuse 16 and 17 (right&left low beam fuse). Fuses not blown, but replaced anyways. No low beam headlights.

I have no rear light while my headlights are on in the whole back end of my truck. Went through and checked all the fuses and bulb but can’t find the problem

No dome lights, radio, power windows or other electronics. New battery, checked fuses, including ground. Cluster is off. Truck starts and drives perfectly fine with headlights and tail lights working including blinkers. Help!

Everything is working fine at the front and inside the cab ( turn signals, headlamps high, low beams ), but the tail lights are out completely, no turn signal, stop or running lights. I checked all the fuses inside and even under the hood and eveeything seems ok. Can you please help? Thanks.

Put in new led lights driver side low beam stopped working any ideas checked all the vonnections

High beams work but low beams do not

Dash lights come in acc with all indicator lights as soon as you start it the go out...I still have headlight and tail lights high beams ect

Lights instruments radio fans go off now no high or low beams come and go buzzing in dash

Changed heater core, now headlights and dash lights do not work. Flashers work okay.

When my headlights come on the passenger side comes on high beam while the drivers side comes on low beam and after a while the passenger side will go to low beam. They are the high intensity headlights.

I connected the battery from a Nissan titan to my ford f-150 king ranch. The alarm came on n the wires going from the battery to alternator started to smoke I quickly disconnected it. Then connected it correctly drove truck about 3 miles: once I was home I put in new battery and new alternator. But the battery wont stay charged. & head lights stay on. On the fuse box in the passengers side one of the fuses keeps blowing out.

Just started...daughter noticed it as I left her house...while parked everything works fine...a few days ago the little indicator light on the gear shift console stopped indicating it was in drive...but worked in park...and high beams won't stay on(doesn't 'click' and stay on) but works when pulled back to flash high for a moment...only the tail lights are a problem??????

My highbeams won't work also radio won't work

I have no turn signals or brake light I checked all the fuses and they look good and all the running lights work like high and low beams and I have tail lights
Just no turn signals or brake lights

The side high beam isn't working, low beams and right side high beam works good, I installed new headlight bulbs but no change

I have high and low beam head lights and all the running lights but no turn signals are rear brake lights

Whenever i turn on my truck i cant see my speed and night, but the headlights and side door lights still work, ik i could be the dashboard light bulb but could it be a fuse

Installed low beam high beam and fog lights LED started truck up fog lights come on low beams come on and then shut right back off not sure what could be causing this problem

My 2013 f-150 King Ranch turn signals, high beam, controls on the steering wheel, and headlights not turning off. I've changed switches, fuses and they are still not working.

One of my turn signals don’t work. My passenger tail light. I have aftermarket tail lights and head lights but for some reason the LED running lights work but break/ turn signals don’t. I checked the fuse and it’s good the resistors are new for the LEDs so I assume it’s good. I checked voltage and I’m getting 14v at both fuse box and wire harness. It’s not the tail lights because I also bought new aftermarket tail lights and tried them and still didn’t work which I’m returning cause now i know it’s an electrical problem somewhere. If somewhere could help I’d really appreciate it. I really don’t wanna take it to the dealership.

My passenger side high beam is not working. I have checked the fuse and bulb and it is still not working. What else could it be?

The check engine light and the light that looks like a wrench are coming on recently and last night when I was taking off the ABS light came on the headlights got real damn in the engine stalled and then pick right back up and then stalled again I killed it and it crank back up normal and ran to town and back but on the way back ABS light came on and it stalled again

No power to anything inside of truck. Nothing changes when key turned. Geting a 4% feed back in wireing. Battery fully charged. Clicking noise coming from hazard signal box under steering column. I have headlights. Power at the starter. All fuses are a1. Changed out the whole fuse box. Checked all grounds good. Im stumped here. Can anyone help.
