The switch will have an "A" position for auto.
No switch it has a relay auto turn on
(http://www.wjjeeps.com/lamps/headlamps.htm) AUTO HEADLIGHTS CYCLE ON AND OFF WHEN THE VEHICLE IS PARKED AND TURNED OFF (with headlamp switch in "Auto" mode) The problem is most prominent on 1999-2001 WJ's, but it could apply to the 2002-2004 WJ's. The problem could be in the switch. The switch is a multiplexed circuit, the resistance of the HEADLIGHT ON position is very close to the AUTO position; the switch has been updated to correct this problem.
DIMMER SWITCH FAILURE.
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.
The headlights should turn on and off automatically depending on which setting you have your switch set at. The switch is located on the turn signal lever. I always leave mine on auto.
you just need a new relay switch just go to auto zone, pep boys, or kragen and ask the people at the front to help
Make sure you have it out of AUTO LIGHTS ON. Do the lights automatically come on when the car is started? If so, the Auto Lamp switch may be on.
Just leave the light switch (right hand side of steering wheel) on Auto, the car will do the rest.
Set your light switch to "auto" on the dash and your lights will come on automatically with the ignition. Turn your light switch on your dashboard to "auto" or "automatic" and the lights will come on and off with your ignition switch.
Turn off engine. Depress Emergency Brake. Turn on engine. The lights will not turn on until the E-Brake is released. Get in the habit of setting the E-Brake and you will have less of an issue with the auto headlights. I don't think there is an easy way to bypass the auto headlights entirely. The headlight switch is essentially, "just for show."
It means that you can leave your lights on the "off" position and once it gets dark enough outside, they will turn on automatically. This is a great feature, because most people don't know exactly when to turn their lights on. Some vehicles require that you turn the switch to the auto mode for this feature to work. Otherwise, they work the same way.
