Sorry, I was not specific enough. Every function except MAX A/C works. The selector switch can be moved through all positions with each functioning properly such as defrost, floor, vent, combo floor and defrost. Only MAX A/C is not working. The door behind the glove box to the far right that lets air in from the cab does not open when MAX A/C is selected.
