I'd guess you need to replace the headlight switch. The switch for a 94 isn't too expensive but it IS a dealer only item. The center of the instrument panel comes off with the 4 screws in the corners. Pull the instrument panel, disconnect the plug to the switch then remove the switch from the panel. Recognize that the switch assembly has 3 parts, Headlight switch to turn the headlights ON, clearance light switch that turns on the clearance lights and dash lights and dash light dimmer assembly. It all comes as a package and I think GM had a problem with a few off their trucks for the years that used that switch assembly, so the switch is quite cheap.

30 minutes after sunset

Headlights are required to be turned on in Tennessee 30 minutes after sunset to 30 minutes before sunrise, when visibility it low, and in adverse weather conditions.

30 minutes before sunset

Headlights should be on at least 30 minutes after sunset and can be off 30 minutes before sunrise. They should also be on during times of limited visibility, such as in rain or when it is snowing.

Legally (at least in Missouri) headlights are required 30 minutes before sundown until 30 minutes aftersunrise.

Most states require you to turn on your headlights a half an hour (30 minutes) BEFORE sunset. (That is based on my experience, driving mostly in the Northeast.)

If a Ford Explorer headlights blink on and off after 10 minutes of driving, it is highly probable that there is a short bad overdrive pump. Rest the car and clean the grounds. Also check for loose or broken wires.

Where I live it is 30 minutes before sunset and 30 minutes before sunrise that you are supposed to have your headlights turned on.

I had this problem with my 1994 Buick LeSabre and it no longer happened when I installed a new battery. It's been at least 6 months now with no recurrence of the problem. Before the new battery, I noticed that if I waited about 5 minutes after turning off the car, I could get the lights to turn off. Seemed like something had to cool down.

Bad headlight control module located under dash on drivers side

When the headlights don't turn off when you turn off the car, the issue is probably a stuck relay. If you disconnect the battery for a few minutes they will go out. This is just a temporary fix until you can get it to a mechanic.

i was driving in the rain last night my headlights and wipers quit working and i stop the car for 15 minutes and they starting working again and they are still working what could have cause this my car is 2002 cavalier

There are two tiny buttons under the volumn knob. One for hours and one for minutes. Press in and hold and in about 5 seconds it will start to change the hour or minutes depending on which one you have pushed. The left is for hours and the right is for minutes.

turn stereo off,push set,push seek for hour and scan for minutes

Yes. The headlights shut off after a couple minutes if the ignition is off.

Hey Fred==Your car probably has auto headlights and has a module under the dash to control them. The module is bad. goodluckJoe How long do they stay on? They're supposed to stay on for about 3 to 5 minutes.

i doubt this will work but it worked on a ford tuarus, disconnect the battery and turn on headlights for 5 to 10 minutes then reassemble

Your auto headlight switch only controls the delay after you turn off the ignition, if it's dark enough. The closer the pointer is to the 12 o'clock position the less time they will stay on, turn the switch more to the left and the headlights will stay on longer, up to 4 minutes. That switch has nothing to do with the sensitivity of the auto lamps, only the delay.

About 45 minutes unless you get on the suburban route to Queens Street which has been known to take two hours.
