Question about Ford F-150

1 Answer

Headlights Smelled insulation burning, pull over. Headlight switch. Heavy orange/black hot in (connection "A" on the switch) has some insulation burnt within a few inches of the connector block, and switch itself has more melting there, BUT... The wires that actually burnt insulation and filled the cab with smoke come off connection "R" on the switch. These are burnt bare as far as I have traced them, they split and go into wire bundles left and right from switch. Can't tell you color code, no insulation left. Turn signals still work, brake lights no, that must go through the headlight switch. I'm thinking if I can find a wiring diagram telling me where wires from "R" go, I can run new wire without physically tracing the bare copper. I already have the instrument panel and most of the dash on my living room floor. Truck still runs. Speedometer hasn't worked in a long time, but for in-town, I don't need it. BTW, which wingnut designed the dash connector for the speedometer cable? Ford did NOT have a better idea that day. About half of what LMC calls "instrument cluster plate 'D'" disintegrated when I pulled it. No problem with the printed circuit, but I will have to blow $80 on a plastic box to get the wire bundle connector to make contact with sais printed circuit.

1. electrical problems are the hardest one for the cars, houses, apartments and etc.
2. I owned a Union 76 services station and a car stero, CB, TV specialist shop in LA. CA, if I were you, I will go to the junk yard and get a whole set of the wire to put it in, because all the wire connect together, there are many terminals, if you take to the car repaired shop or dealer, it will cost you a lot of money.
3. When you change this kind wire yourself, you have to watch out ;

a. Do not unplug any wire connecters at the same time, it will cause you some confusion.
b. Be sure give the model of your car clear to the junk yard to let them find a right part.
c. If you have the right part, remove your connecter one at a time and or you can write it down every step.
d. It is a big headache, believe me. Maybe you have a better way, because you know your car better than I, I trust you can manage right.
e. watch out the circuit board

Good luck my friend, if you need more help, I like to discuss with you.

I have a 2000 Monte Carlo SS, low beam headlights do not work. I have changed the headlight relay, headlight switch, checked all fuses, checked all bulbs, and cleaned the ground wires. What next?

As you can see from the diagram, the orange wire is voltage and fuse protected. The fuse circuit is hot all the time. Not only check the fuse, check the fuse circuit for voltage.

Headlights won't turn on

Five most common possibilities:
1. The headlight bulbs are burned out
2. Blown fuse or fuses
3. Bad lighting relay
4. Bad light switch
5. Bad electrical connection; could be a bad ground, bad connection in a plug in the harness, bad connection to a switch or relay, wire worn through the insulation and causing fuse to blow

Electrical burnt smell

If you had a short in the starter motor windings and held the key, you'd get a click and a burning smell. That would be the insulation burning off the electrical windings. There's a 40-amp max fuse in this circuit.

1986 f150 lights flicker

This problem is caused by a burnt headlight switch and the headlight switch connector. Pop the panel out and remove the switch, you will see the contact blades which should be a bright brass color are burned looking. The headlight switch and the connector are available from most parts stores like Carquest and Napa and the Ford dealer of course. When you install the repair connector do one wire at a time, solder the connections and shrink tube them. YOU MUST REPLACE BOTH PARTS

Both headlights are not working in 2002 Safari Van

Check both headlight bulbs, check for power and ground (the ground wire is black). If no power either wire to ground remove the headlight switch in the dash. The bezel around the cluster just pulls away. Check the connector to the switch. The large red wire (power) or the black (ground) may be burnt. Repair if possible or replace if melted. There isn't a headlight fuse. If only one setting works (eg. hi beam only both sides, no lo beam) then the dimmer switch is at fault. Its part of the turn signal switch.

2000 buick regal headlights are turning off intermittently. Headlights come on but turn off when driving then click back on after different periods of time. No headlights or highbeams. I do have...

When the headlights go out, check for power to the low beams on the orange (RightT) and orange/black (left). If you're getting power, then the problem is on the switching/ground side of the circuit.

The body control module uses the ambient light sensor as an input and the headlight switch. If the light sensor see dark, the BCM provides ground to the control coil in the headlight relay. When the control coil is energized, it closes contacts that provide the ground path to the headlights. Since this is intermittent, I suggest tapping on the headlight relay with a screwdriver handle when the lights go out. It's located behind the glove box. Or, try swapping the relay with a different one and see if that solves the problem
