I had an A/C issue that I just figured out-problem was the A/C wasn't coming out cold as it should be.

So the other day I accidentially pushed the recirculation button ON while driving with A/C on and within minutes it was ice cold. So to see what the hell was going on i turned off everything on climate control; no blower motor, A/C, or recirculation. When driving, air comes through the vents but when driving with recirculation button ON(illuminating amber), no air comes through vents.

So my question is: Why is my recirculation button acting backwards than it should?

 

It's acting exactly as it should.

When the recirc button is OFF, that means the heater intake damper is open to let in fresh air. When you're driving, there is a negative pressure around the area just under the hood where the intake is located, and so that sucks air in through the vents, even if the blower is turned off. If you crack open your sunroof, even MORE air will come in, since the air rushing over the sunroof opening creates a low pressure and sucks air out of the cabin, which in turn sucks air in through the ventilation intake.

So then if you press the recirc button, the damper closes, and outside air can no longer come in. So if your blower is also off, no air will come through the vents.

There was also nothing wrong when you had the A/C on and turned on recirculation. That makes the cabin cool faster because it's recirculating already cooler air from inside the car instead of taking in hotter air from the outside and cooling that down. Recirculation mode on Japanese cars is the same as Max A/C on American cars. Max A/C mode on American cars just close the fresh air intake damper to cool the inside faster.

 

very very well said. to guys above me.

and, just make sure the **** is all the way to the cold. because on mine, i have to force little more to get the click sound on full cold.

 

yeah I'm not sure what that click sound is for at each end of the slider. All it's doing is moving the coolant valve just on the other side of the firewall to control how much coolant flows through the heater core.

 

Wow thanks for schooling me on that one. If i remove the resonator, will that effect anything important?

the engine air intake resonator? Or the exhaust resonator?

 

Intake resonator...it sounds like the intake damper may be around there.

 

haha no I was talking about the cabin air intake duct, which is located under the dashboard and pulls air from under the cowl trim. You can see the opening in this pic, with the blower fan visible below (ignore the arrow, that doesn't mean anything). When you push the Recirc button, a damper/flapper door closes that opening so that no fresh air comes in.

You can see the flap opening in the inside of your car when you switch to recirculate. It is on the front of the blower motor.
