My 2013 Accord has developed a problem with the air conditioning. Each time I turn it on, the 'inside air' function activates. As you probably are aware, when the inside air function is on, the blower noise level is higher than without. I can manually turn the inside air button off, but the system remains on inside air.

This happens each time the unit A/C turned on and will not turn itself off, as it's designed to do, after the interior has cooled down.

Have any of you had this type of problem with any late model Accord? Wanted to check with others before I entrust the car to the dealer shop. I like to have an idea of the problem, in advance.

Thanks
I don't think this is a problem but the way the system is designed. In the automatic mode the system will try to drive the inside temperature to the selected value. This is accomplished faster by cooling the air inside the car instead of bringing more hot air inside. When the temperature reaches the selected value it reduces the fan speed and eventually switches to outside air from recalculate. It's been so hot here in Texas that it takes a long time for the system to switch over to outside air. On my drive home in the afternoon it sometimes doesn't switch for the entire thirty minute journey.

I will give the programmers the benefit of the doubt that they programmed the system to know that if it IS extremely hot outside (maybe humidity affects it too?) no matter what always recirculate. Maybe that Econ button only allows to recirculate too! It is supposed to affect the ACoperation when operating and maybe that's what it is doing. Less demand with recirc air than outside humid air. Did you have Econ on?
Lately in Chicago area even with 80's my recirc does turn off automatically when it reaches thermostat setting. Econ is off too.

The Econ button doesn't seem to make any difference with the recirculate button in the AC auto mode. I have run 2 tanks of gas each with and without the Econ button on in July and August and I can't tell any difference in the AC performance. I run the system entirely in the automatic mode.

By the way, the difference in mileage was negligible.

Does anyone know where on the dash, or nearby, the AC sensor is located? It could be the sensor is set incorrectly, or in fact, may be sitting directly in the sun - if on the dash. I've looked at the dash and cannot see one. On my previous vehicle, the sensor was at the front of the dash, in front of my right knee area.
The location of the sensors is found on page 145 in the Coupe owner's manual. If you have the sedan look in index under Airconditioning sensor.

There are two sensors a sunlight sensor on top of the dash and the temperature sensor is at the bottom of the dash to the right of the steering wheel.
