How do you disable the automatic headlights on a 2001 Canadian Chevy Astro?

The 2001 Chevy Astro, even the Canadian version, didn't come standard with automatic headlights. The headlights are controlled manually. There's no setting to disable something that isn't there. If your headlights are turning on unexpectedly, there's a problem with the vehicle's electrical system that needs to be diagnosed. Possible causes include:

* Faulty headlight switch: The switch itself might be malfunctioning, causing the headlights to come on unintentionally.

* Wiring issues: A short circuit or damaged wiring could be sending power to the headlights when they shouldn't be on.

* Body control module (BCM) problem: While less likely on a 2001 Astro (they're simpler than newer vehicles), a malfunctioning BCM could be incorrectly activating the headlights.

You need to take your Astro to a mechanic or qualified auto electrician to diagnose and repair the issue causing your headlights to turn on unexpectedly. Trying to "disable" something that isn't a feature of your car's design is not the solution; fixing the underlying electrical problem is.
