Headlight is probably not the problem, espeically in light of the burned plug, replace the plug and any wires leading up to it that are overheated or you will have continual problems. Once a connection overheats, it looses all temper and cannot squeeze tightly enough, and the material oxidizes, creating resistance, and both pieces need to be replaced or failure will occur again, quickly.

On the door sensor, meaning door light switch, unscrew it and disconnect the wire(s) at each switch.

Interior lights work, tail lights and fog lights work but no head lights hi or low checked fuses all OK. 1993 Chevy p/u 1500 Manuel 5spd how would i know ifs it's the head lamps or they need to be...

quickest way is to use a test light at the plug connector at the headlight and check for ground and power to the connector.if you have both then the headlights need could also grab a good light and plug to the connector and turn on the lights and if it lights then again the headlights need replacing.if you have no grounds or power at the connector then the ground side will need repair.if you have no power then you could have a bad headlight switch on the headlight circuit of the switch and it will need replacing.

My head lights won't work. My running lights and dome light work and so does my turning singals.

Probably need to replace your headlight switch, it could be another problem but that is where I would start. The headlight switch is 2 or 3 switches in one, it turns on your parking lights, it turns on your interior lights and dims them too. Either that or it's your bulbs but they say you will never burn both headlights out at the same time. If you have a test light or a volt meter you could check the voltage at the headlight, that would eliminate the switch.

If you plan on taking this problem on yourself, you most likely will need a wiring diagram, to track grounds and wires. Could be a short in the wiring causing the switch to go out. It is VERY unlikely for this kind of problem to happen more than once within a short period of time.. I dont mean to branch out and question your mechanics integrety, but in my experience, it SOUNDS like he MIGHT of replaced a fuse and called it fixed. A basic understanding of electricity could be a fix if you plan on doing so on your own. A simple resistance test throught the wires and switch would lead you to the bad wire, or switch. A couple other things to check would be your alternator (for OVER CHARGING), and a fuse diagram (to make sure somebody didnt put a high amp fuse where they shouldnt have....
Always check your fuses and relays first, cause it's cheap. Not to ramble solutions at you, but there might be a connection between your ignition and your headlight (so you dont leave your headlights on when you turn off the car) that might be bad, again, look into your wiring diagram to determine this connection.

All four of my marker lights do not turn on when I put the lights on. Head lights, brake and turn signals all work. All fuses are good. Where to start?

If the fuses are all good then you likely need to replace the headlight switch or the harness to it could have some burnt pins in the plug to the switch.

Did you check the wiring when you replace the switch? Some times the plug that you plug into the light will be melted or burnt. I know cause I had 2 - 5.0 stangs and both did the samething. Is the car equip with fog lights? If so I would disconnect them. I found that the fog lights on my 89 gt cause the head light switch to over heat and melt. On both I had to repair the wiring at the plug.

02 SS Monte Carlo , dash lights have quit working, well all interior lights for the controls and switches. checked body control module its good , no blown fuses

this only occured when the ambient light sensor turned on the headlights when it got to dark. if that is happening then check the headlight switch, the one that also dims the interior lights. mine had a burnt connector and fried the circuit board. replaced it and it works good. check for lose wires and connectors in there as well which likely caused the short.

The switch to the head light is shorting out and taking out the head lights. The other problem could be the body control module is shorting out .
I would replace the head light switch first. Then if that does not work take to a shop to diagnose the vehicle.
