Hi,

Often the electrical design of the vehicle would feed the headlight switch from the fuse box. The headlight being a heavy consumer would have its own separate fuse. Further being a heavy consumer denotes high current passing through the wires. It is also possible that the connectors (at different points) would have been burned or corroded. The best order of checking would be fuse, fuse snaps/cradle (where the fuses are inserted), fuse block and/or fuse block connector(s) including the internal jumpers and wire/wiring harness. A DVM would facilitate checking the +12 at various points.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I have a 73 chevy van headlights not working and I need to trouble shoot it.?


Check for 12v going to headlights, if headlight plugs are getting power then both headlights are burned out.
Check the headlight switch for power coming into it. If its getting voltage in, and headlights not working, then its the switch.
If switch isnt getting power, check for a blown fuse in the fusebox.

My headlights wont work


I don't believe there is a fuse. There is a circuit breaker built into the headlight switch. If you are sure the headlight switch is good, it could be a bad dimmer switch. If you have a voltmeter, with the headlight switch turned on, a larger yellow wire going from the headlight switch to the dimmer switch should be a hot wire. The dimmer switch sends power on a tan wire to the low beams, and through a light green wire to the high beam bulbs.
If your high beam indicator on the dash also doesn't work, then it is likely one of those switches. A voltmeter or test light would need to be used to find which one is bad. If you can find the connector at the steering column going to the dimmer switch, pull it apart and check for power on the yellow wire coming from the headlight switch, with the headlight switch turned on. If no power, the headlight switch is bad. If there is power there, then the dimmer switch must be bad.

Put a new multifunction switch on an it didn't solve the problem, still no power on either side of the headlight fuses


The power goes thru the fuse, then thru the headlight switch, then the dimmer switch. If you don't have power at the fuse you may need a shop manual to get the wiring diagrams to trace the circuit back to the battery. Its supposed to be hot all the time.

86 samuria . The right head light is dim. I repaced the bulb but


The common cause is that the wire for dip beam is badly corrioded and not making a good connection.
Unplug the connector and inspect all the wires and terminals at the headlight.
Clean and replace the terminals if needed.

Neither tail lights nor dash lights work when headlights are on


I would start by replacing the light switch as I have repaced many in the past for this concern also check the light switch connector as they have been known to melt.
