At 85 degrees the dash A/C should keep the driver and passenger comfy. I suspect that you are getting heat from heater core. I suggest that your dealer can fix that but you might want to put a clamp on the hot water supply to the heater box.
For perspective. I have a 42 foot coach with a 19K BTU A/C in the dash and a 13.5 K BTU over the road evaporator in the bedroom. At 85 and humid the front is comfortable with just the dash unit on. It will blow a lot of air at 47 degrees.
If it gets much warmer we'll turn on the bedroom evap. The wife complains that is too cold even when ambient is 100. Theses things really do work when designed, manufactured and maintained properly.
Good luck with this problem.
