We have 06 EX-L model with 54k miles, I noticed yesterday that even though outside temp was 80 and set the car inside temp to 69 and turn on "Auto" mode it was automatically turning on recirculating switch and bringing outside air in but vents are all blowing hot air and even when I change the setting to manual and turn the a/c on and setting the temperature to low. Any idea what can be the problem?

Thanks
