My Auto Headlights do not work. I check the Fuse 29 and it was not blown. I can manual turn the lights on. What other checks should I be doing?

There is a relay on the fuse box under the hood and there is a GEM that controls the entire system. The GEM is under the center of the dash and it is not cheap.

SOURCE: electrical problem

I finally broke down and took my truck to the dealer. It took them two tries, but they finally figured it out. It turned out to be the wiring harnes for the shift lever. When it exits the steering column, it was being chafed, and eventually wore through a wire and was intermittently shorting. It would blow a fuse (don't remember which one - I think it was on the bottom row, third in from the right. 20A). It stopped the alternator from charging too. They replaced the shifter harness and the problem went away. I did get a ticket while my speedo was inop however.

It is a possible option that the relays for the Stop / Turn are having an issue or the fuse in the Engine Mini panel is blown ( page 142 of the 1997 owners manual )

On the 1997/98 MY this is in the aux relay box in between the Engine Compartment fuse panel and the engine mini fuse panel.

The output of the MFS ( Multifunction switch ) triggers the relays, to use the trailer tow fuse to operate the trailer lamps. The fuse to supply power to the Normally Open contacts on the trailer relays should be hot at all times. You can verify this with the diagram below by metering from pin #3 to pin # 2 [ground for coil] or to another known ground.

These are 1/2 size Ford ISO relays, and can be jumpered to make testing easier ( and with this diagram you can bench test them with a meter to check resistance over the Normally Open contacts, when applying power and ground to the coil ).

I am not 100% sure on the 97/98 MY F-150 about the location of this connector, but the 99-03 have all the wires to the rear of the truck via a connector along the driver's side frame rail, that you can check for ( easiest with the spare lowered )

Start with the Fuse in the Engine Mini panel, to see if the 20A fuse is good and work back towards the trailer tow adapter via the relays. I am going with the obvious blown fuse for the Stop/Turn lamps for the trailer.

Why do I have no auto night headlights, no electronic mirror adjustments and no auto locks. They all quit on my 3/96 4.6L single cab f150 lariat, why?


after all fuses and relays verified are working it sounds like you have keyless entry on the door panel with a keypad and in either case theres a driver door module inside the door panel this may have gone or the fuse for that has blown I'm ssuming that you have the owners manual with the diagrams if not ford owners .com register then download your manual then go to roadside emergencies and the fuse and power distribution box diagrams are there also this could be you headlight switch so if the fuses are all good then lookat the door module on the drivers side next to the speaker or the headlight switch do the windows work also check the master window switch this is because all components have some borrowed power from other wire circuits so look carefully at all of these even a corroded wire or contact can cause havoc on other systems clean al and a light dab or spray of wd40 will help you good luck Stephen

MY HEADLIGHTS WONT COME AUTOMATIC WHEN I START MY TRUCK.2002 F150 HAVE TO TURN ON MANUAL. WHATS WRONG


Did you check the fuse for the autolamp module ?

This is fuse 29 in the cab fuse panel.

Next is to check the fuses for the autolamp relays for the parking lamps and the headlamps. These are engine compartment fuses #3 and #6.

You do not make mention if the parking lamps work or not, so I will take it to mean they do not, and I would suspect the fuse for the autolamp module.

Cannot disengage overdrive on 2003 Ford F150 4.2L


Check the Fuse for the OD function, this is cab fuse panel fuse #29, 5A.
If This fuse is blown, chances are the wires at the end of the shift lever are chaffed and causing the problem. This happens some times ( can't say why ), but it is simple enough to check and repair the wires if the insulation is chaffed.

Headlights wont turn off on ford f150


Possible cause is that your fuse is blown, or switch is malfunctioning.
Try to check the fuse first.

Overdrive button on extend cab ford f150


Problem Solved Look No Longer. Overdrive switch fuse blown, auto door locks not working, fuse after fuse after fuse, chasing wires grrrr. Remove the steering column cover (3 screws from the bottom) opens like a **** shell. Your switch is located on the shift lever, the wire for the switch is routed through the handle and comes out where the shift lever mounts to the column. Look very closely at the wire in this area. Most likely rubbed through. MR
