New headlight switch installed same problem no headlights fuses good under front hood is there a fuse box in trunk for the headlights


there could be a black plastic box that has fuses but also you will find relays. From the relay you can find the socket that feeds 12v directly into the headlight and see if headlight is ok and if the relay is suppling 12v to the headlight. Also from the relay you can also check if the switch is supplying 12v to the relay coil with a voltmeter or a 12 volt probe tester. you may have a faulty relay but you could test this via a volt meter.
you may have blown globes by getting a wire and putting terminal connectors that match the relay legs and manually supplying the 12volts to the headlights from the relay socket you can test if the globes light up . So basically you are doing the relays job

Why won't 2002 Chevy express van with Sidewinder security system headlights shut off when headlight switch and key is off?


Either the headlight relay is stuck on, or the security system's headlight control is shorted and keeping the headlight relay on. Find the headlight relay (probably in a fuse and relay box under the hood), remove it and check the contacts with an ohmmeter. They should read open in a good relay, but will read little or no resistance if the contacts have welded together ( a possible result of rapid on-off cycling).

Where is the headlight relay located on a 2002 PT Cruiser?


Did you check the fuse box inside the cabin ? The book says the relay is in the fuse block but does not give a description.
Keep in mind the headlight relay only affects the headlights. The other lights you mentioned are on different fuses and not the headlight fuses.

No Headlights


In the late 1990s GM and most other car companies changed the configuration of headlight circuits. Now the headlight switch provides the ground circuit instead of power. So yes there is a relay between the main switch and the dimmer.
The headlights get power from left and right 15amp fuses, and the relay and main switch provides the ground circuit. Your owner's manual should tell you which relay in the box is for headlights.

Does a 74 olds 98 have a relay for the headlights?


It has a headlight switch. Pull the knob out and it goes from off, to parking, to headlights. A (foot) press switch on the floor controls the low and high beam. The (low) wattage of the headlights back then and not needing to run small wiring through the turn signal switch, allowed them not to require a relay to run the headlights. You have two relays. Your flasher (turn signal) relay - under the dash. And your horn relay mounted on the firewall.

1986 Supra. Head lights pop up but does not turn on.


the headlight pop-up circuit is different from the lights themselves. Check the headlight fuses in the engine compartment fuse box. If the fuses are good then check the headlight relay. It is in the same fuse box just behind the headlight fuses. (The headlight relay is the second relay from the right side of the fuse box. the relay at the far right is the electronic fuel injection main relay.)

98 ford taurus headlights will not go off


either the headlight relay is stuck on. or the daytime running light module or relay is bad. to confirm find the relay center and switch the headlight relay out with another relay with the same part# on it. there should several in the relay center with the same part #. If this fixes the problem get a replacement relay. if not try switching out the relay for the daytime running lights. if no dice then unplug the daytime running light module.
