draining battery

Duc_Z09

I didn't see an electronics specific tech section so I'm posing this here... Mods can move it if they want.

Apparently the "auto" feature on my headlights isn't working, and I woke up to a dead battery yesterday morning. Load test says the battery is fine. It charged right up again anyway, and the charging system on the car has everything running just above 14 volts, like it should be.

Last night I went out to the garage just to make sure everything was still OK and guess what, my headlights/taillights were still on. I checked and sure enough, lights were set to "auto." Of course I turned it to off, and that's the reason I was able to drive to work this morning.

Anyone else ever have this problem or know how to fix it? I could just not use the "auto" feature (I never trusted that **** anyway and this is exactly why) but dammit, it should work the way it's supposed to! I also don't want an "automatic battery drain" button anywhere in the car where it can be accidentally turned back on.
