Automatic headlights

Last night my ALC system stopped working so when I got home I dug the manual out. One of the things it mentioned was if the emergency brake is on the ALC doesn't work, which makes me think there is a switch somewhere that the linkage trips when you pull the brake on. If there is a switch and being winter in Wisconsin I'm wondering if the switch would be mounted somewhere where the ice and snow could affect it? The lights will work on Manual. If there is a switch could some tell me where it's located? The Vibe is a 2003 model

The parking brake switch is in there right with the parking brake handle in the center console between the front seats, so hopefully it's not jammed with snow and ice Also, if that were sending a false indication, the brake indicator in the instrument cluster should be lit up, since it is triggered by the same switch.

resurrecting an older thread... so i just noticed yesterday, that my ALC won't turn off. the last few days here have been bright sun, no clouds.usually, i'll start the car, the drl comes on and if i go into a tunnel or something, the headlight indicator on the dash comes on, but the last couple of days, the dash indicator is on... no way to turn the full night time driving lights off?

If there isn't a shadow from the 'A' pillar falling on the sensor, and the light levels are not low enough to cause the ALC to kick in, it almost sounds like the sensor is bad...You can revert back to DRL-only / manual light control if you disconnect the sensor. If that doesn't happen, then I would suspect a DRL relay issue. Might be worth a shot to see if it's the sensor or DRL relay. To get to the wiring for the sensor, pull the gauge trim ring panel off and you'll see a white connector with 3 (green and varying color stirpes IIRC) wires in the harness clipped to the top of the dash above the gauge cluster. That runs to the sensor, if you disconnect it you'll hopefully have manual control of the lights.

Mine is doing the same thing did you figure out why?

Make sure there's nothing on the dash blocking the sensor.
