Humtech - I didn't even realize you are actually in Canada.
I am pretty damn sure that the truck came from Canada.

It has to be that damn ambient light sensor!! You hit the nail on the head.
Now how can I fix it?

You might be able to reach it through the glove box opening i cant remember. Make sure its plugged in. If it is without a scan tool and checking it out could be the sensor, bcm or wiring in between

Thank you once again.
I am pretty sure it is the wiring because the lights will not operate from the light switch. They are on 24/7 if the car is on.
I will check in the glove box and see if I can see the sensor or any wiring.

What is BCM?

Okay, tonight I was going out and the lights went off. It was almost dark. I flipped the light switch to the on position and they still remained off. I was not dark yet. So I went to take a drive. The lights remained off, but then I got to where i was going and the lights went back on and I could turn them off by putting it in the auto position on the light switch. Pretty strange.
Now Its dark out and I can see the auto switch lite up on the light switch, but they will not go off.....maybe because it is dark outside??
So, I got a flash light and shined it in the ambient light sensor and nothing.
Could not get them to go off at all. Totally driving me nutz

Any ideas? loose wire? That would be my guess?

HUMTECH - any suggestion?

The light is lite up on the light switch on auto (green) and off (amber) .......i'm trippin
