the popping is probably just the floor vents opening up...as far as the a/c light im not sure... maybe its a setting for the defrost or something.

I've been meaning to post this. when I switch from my defrost to any vent the AC turns on also. Anybody else have this? It easy enought that I just turn it off. but this happens even when the heater is on, which right now is the case.

Are you sure the AC is not turning on when you spin over to the defrost or heater/defrost? It's meant to do that, if that's what is happening.

I always turn off the heater when i leave the truck. when I turn it on i proceed to hit the defrost botton and move it 90 degrees and desired air speed. Once the windsheild is clear I set it for defrost/floor at that point or any other combination the AC turns on or that is what appears on the display until i hit the AC off. I will take pictures this evening.

Oh sorry, didn't know you had the auto climate control system.

I have no idea, I don't have that.
