How do you stop the AC from coming on by itself, the AC Auto buttons come on while driving. I hit the off button and then about 5 min later they come back on, is it a setting in the computer that is turning it on.

 

Have you tried just pushing the a/c button and not using the auto function?
I have noticed that sometimes in mine the auto button light is not on but then neither are any of the others and the A/C is on where I left it. so I just push the A/C button and no more auto. But I have yet to have a problem with it though.

Good luck

 

Is it set on defrost? That usually kicks the ac on.
