Air conditioning works fine at idle- blows hot air at highway speeds. This seems almost backwards to me.
No check engine light or messages in Driver Info Center.

Sometimes works ok @ highway speeds, but seems to almost always work ok at idle and below 40 mph.

This started happening all at once last week.

When it is blowing hot air, it kind of smells like cat poop.

When blowing cold air, it is REALLY cold-just like it is supposed to be.

Could be freezing up due to air and moisture forming into ice and blocking off the orifice or the air blend door actuator is acting up
