The three way the headlights come on: The headlamps may be turned on in three different ways. First, when the headlamp switch is placed in the ON position, for normal operation. Second, With the twilight switch placed in the ON position, for Automatic Lamp Control (ALC) . And third, with the twilight switch placed in the ON position, with the windshield wipers ON in daylight conditions, after a 6 second delay.

Try turning the twilight switch off and see what happens.

The twighlight switch you are talking about is only to set a delay after you turn the car when the headlights were already on, older models used to totally control the headlights like a 95 Cadillac Sedan Deville we used to have

hmm thats weird

I guess when you turn the twilight switch on, the ALC takes control on the headlamp control. If it sees the wipers come on it turn on the headlights. If youuse the twilight function your headlights will come w the wipers coming on. Not much you can do.

My twilight control ONLY sets the timer for auto turnoff of the headlamps, and turns them off if it'* dark and I'm in park.

I stand corrected. I checked out my headlights today after work. I turned on my wipers and my DRL'* turned off, and the headlights came on. So that works. Now, if I could only figure out a way to turn my DRL'* off without disabling them.

If it'* daylight out and I switch to parking lights, they parking lights come one...but the DRL'* don't shut off. I've never owned a car that does this.
