No Max-AC

I have a 2014 motor home on a Freightliner chassis. Tried the max-AC setting on the air conditioner for the first time and there was no change from the normal AC setting. I know that it is under warranty but was wondering if anyone had any idea as to what the problem could be.
Thanks.

    If you're talking dash A/C the only difference between A/C and Max A/C is that the recirculation door is closed in Max forcing only interior airflow over the evaporator rather than pulling air from outside. Are you sure it's not doing that?

    In most cases, the speed will change as well and go to full throttle. If not, then starting out that way will then slow somewhat when switching to other modes.
