OK....Thanks for the info. I really appreciate it. I've read that, though, and I think there's a misunderstanding of the issue and/or a misinterpretation of this PDF document. First, the issue that we are having is that the Reciruclate Air is turning OFF (to let fresh air in) on it's own. Regardless of what mode I put my a/c or heater on (defrost, partial defrost, blowing on feet, blowing through main vents), if I press the recirc button 'on', it turns itself off within a few mins. The mode that this document talks about is automatically turning the Recirculate Air switch ON during a/c or heat or defrost operation (to extrapulate a little). This works perfectly fine on my truck. If i turn the A/C on to max, the recirc automatically turns on. Again..the issue we're having is that the recirc button turns off without touching any other controls.

So-am I misunderstanding this?
