F-150 Ford Headlight and Door Lock problem

At about the same time, the headlights on my 2003 F-150 Lariat failed to come on automatically at dusk. Then the door locks refused to lock when shifting to drive. Any suggestions? I can turn my headlights and lock the doors manually. I can get by without this feature if I have to but, heck, I paid for it and do enjoy the safety of it.

The dealer spent 3 hours and couldn't solve my problem. I was in for an oil change and to diagnose this problem. They ask me if I could return at a later date to drop my truck off.

Thanks,

Ray

The fuse for the door locks is in the back of the fuse block. The fuse block is held in with a couple of bolts. There is only one fuse back there.

SOURCE: Ford F150 Pickup 2005 power doors unlock but will not lock

I had almost the identical problem on my 2005 F150 FX4 Extended cab last weekend. The power door locks would not lock using the keypad, remotes, or door buttons. Almost all other functions worked correctly. The doors unlocked, the radio delay functioned, and the interior lights dimmed. When I used the remote the horn would beep twice indicating that a door was open even there was no message on the message center that a door was open. When I used the keypad or remote, I could hear a soft click from behind the seat. I think it was coming from the body security module or body security module - whatever Ford is calling it this year. I pulled the fuse for the Power Door Locks(BSM). As I removed it, I heard a soft click - sort of like a relay resetting. It may have come from the VSM/BSM. It may have possibly been a stuck actuator releasing. I don't think so. It wasn't that load. In any case, everything is functioning correctly now.

SOURCE: 2000 Ford Focus electric locks/acuator failure recurring problem

I would follow their recommendation as I had the same problem with my car. They unhooked the power to that door and it was fine. The problem was a short in the wiring in the door that was causing the problem. So maybe get them to check the wiring in the door as well.

SOURCE: 2000 Ford Focus automatic door locks quit working.

check fuse 63 first.

Visual Inspection Chart Mechanical Electrical

  • Binding latch mechanisms
  • Binding linkage
  • Misaligned door
  • Central junction box fuse 63 (20A)
  • Damaged wiring harness
  • Loose or corroded connection(s)
  • Circuit
  • Door lock switch
  • Door lock actuator



It could also be your GEM (generic electronic module) which is expensive as it controls a lot of stuff. A scan tool can be used to cehck for fault codes from the GEM.

How do you adjust the headlights on 2003 for F-150


Park the vehicle on level surface if it is possible 15 feet from nearest wall. Open the hood and there will be 2 or three screws on top of the headlight assembly. One will move headlight left or right one will move up or down . Turn your headlights (prefer to be a dusk) so you can adjust your headlights on low beam way to get half of the light on wall and half of the light down on the pavement or concrete..Give a test drive and if thet seem to be low or high readjust it again.

2007 ford f-150 fuse keeps blowing when i plug in headlight


Something in the circuit is shorted to ground when you make the connection.
You might want to take a meter and check each circuit in the new plug compared to the other headlight to make sure everything is connected correctly.

Not a regular cab but Lariat F-150 Supercrew 2003 , the inside and the cargo lights stay on when the truck is shut down ,and now I notice the auto locking doors are not working when you touch the brake...


Is the door ajar light in the cluster illuminated ?

Could be the door ajar switch ( part of the door latch ) is gummed up, and needs to be WD-40 sprayed into it, and close open the doors a few times, and repeat.

The autolock uses the same input, to know to lock the doors when you press the brake pedal while moving.

Automatic Headlights don't work on Impala - Police Package.


I have an 2004 impala and every now and then it would lose the headlights for a couple of seconds and they would come back on. I finally replace the headlight switch and the problem went away. A switch, if I remember right, was about $500.
