Vent Blowing Cool Air at Higher Temps or Just Me?

Was the A/C engaged? If so, it will feel cooler than ambient air without it.

 

Air blowing at the windshield means the Defrost is on, which automatically engages the AC on most vehicles these days, including my Liftback. Try selecting some other vent combination, such as feet only.

 

What he said.
I don't think it is possible to have air blowing on the windshield without the AC running.
Now.....the AC LIGHT probably won't be on but that is just a confusion factor.

 

My 2010 blows cold/cool air out the center vents until I turn the temp to 75 or higher.

 

The A/C runs when you push the defrost button, but you can direct the air onto the windshield using the air outlet switch without having the A/C come on. Also, 70 deg. air isn't going to seem very warm (this is a common complaint from heat-pump users). You need to use a thermometer in the air vent to really see what is going on.

 

I believe that is NOT true.
The AC light does not come on but I think the compressor does run a little bit,
to keep from accidentally suddenly fogging the windshield over.

 

I am pretty sure this is not the case. The recirc/outside air will switch automatically to outside air in certain circumstances, but there is no mention of an A/C interconnect with the vent switch in the tech files. I will check it tomorrow to make sure.

Most cars work that way; that is, anytime defrost air is directed to the windshield, it is also cooled just a tad to decrease the humidity. Same reason that recirc is not allowed; to prevent a rise in humidity. I thought that was standard practice on ALL cars these days.

P.S. Noted the 3 dupe posts. I find the "refresh" key useful to verify that a post you thought you sent really made it.
That's F5 on a standard PC keyboard.

 

I do not know what happened...too quick here to assume a problem, I guess. After doing some investigation, it appears that the A/C compressor does run when the vent switch is on the defrost setting. I watched the amp draw today while changing settings. The draw for defrost is the same when using either the vent or the defrost switches. I really do not like these hidden linkages. Why does the A/C light come on for the defrost switch but not for the vent switch? You can turn the A/C off in the defrost mode but not when using the vent switch defrost setting. I do not need the car to make these decisions for me.

 

Not most of the time maybe but you might be surprised at how FAST the windshield will fog over
in the right conditions......and how long it takes to recover from that and get it clear again.

That is especially true if the driver doesn't immediately realize what needs to be done.

It is a safety feature. Whether or not you will need it.....ever......is just a wild guess.

 

The A/C will cycle off and on while in the defrost vent setting....and the A/C light does not come on.

 

You are making this more difficult than it IS.
The AC only runs enough to dehumidify. IF you are adding no heat at all, it will feel slightly cold.
If you add just a tiny bit of heat, then it feels warm.

 

I've noticed in my 2013 IV that cool/cold air comes out of the vents with the climate control turned off. Is this normal? I turn it to my feet if it bothers me and I don't want the heat on.

 

Yes, it's normal. Air is directed to whatever was selected on the display. You can also select recirc and the flow should be greatly reduced with the system off.

 

Also, keep in mind that when you set the temperature, you're setting the desired cabin temperature, NOT the output air temperature. If you turn the temperature up from 65° to 70°, and the car thinks it's 75° inside, then it will still blow cold air. On the other hand, if you make the same temperature adjustment and the car thinks it's 66° inside, then it will start blowing warm air.

So the easiest thing to do is set it to whatever temperature you are comfortable at, and just leave it there. (Obviously, this might vary sometimes based on what you're wearing, if the sun is shining, etc... But it'll at least be close.)
