Heat and recirculate at same time?

[Astroboy]

My climate control is almost always set to "AUTO" at 70F degrees. During the hot summer days with AC on, I engage "RECIRCULATE ↻ " to rapidly cool down the interior air.

However, I can't seem to be able to do the same thing when the heater is on. When the outside is cold and I turn on the heater, the heater takes in the cold outside air, warm it up and send it inside. Why can't I have the heater to take in the already-somewhat-warm interior air and heat it even warmer?

When my heater is on and I press "RECIRCULATE ↻ ", the computer seem to override and disengage it in a few seconds.

Is this normal?

Is my recirculation (blend door) broken?

I have 2008 H2.

Thanks in advance.

well, if it wasn't SNOWING outside today I would go out and check mine...October 16 and snow in NH, what a dump... lol

I have an 09, will give it a check tomorrow as it looks like the heater will be on for the next 7-8 months!

Yes, for a 2003 model. Really annoying... but I guess it's to keep you from fogging up your windows...

Do you mean YES, that your 2003 can HEAT and RECIRCULATE at the same time?

In that case, I envy you.

My other car is VW GTi w/ manual climate controls (cable operated).

I'm able to:
- set the TEMP analog dial to "hot" (heater on)
- switch on "recirculate"
- switch on AC

By turning on the heater, AC, and recirculate, all simultaneously, it would give me a dry warm air (w/ its moisture ridden by the AC). It would keep me warm and de-fog all my windows.

I want that.

Bump -- Just wanted to revisit and clarify this issue.

Both 'recirculate' button and 'AC' button soon deactivate in a few seconds every time I press and try to activate in the last few month (during this winter).

(I have 08 H2, and it has auto-climate-control system with separate interfaces for the driver, the navigator, and the rear passenger.)

- Is it possible to heat the cabin air and recirculate at the same time?
- Is it possible to heat the cabin air and "AC" ON at the same time?

I'm asking this because H2 is my 1st vehicle with auto-climate control system. All the vehicles I owned before were equipped with manual-climate control, and I was always able to perform both above scenarios.

'heat' + 'recirculate' -> for rapid heating
'heat' + 'AC ON' -> for dehumidifing

I'm wondering if other fellow H2 owners are experiencing the same, and this is the norm, or if my climate unit (especially the blend door) is broken.

Thanks.

I just went out and tested mine... 2006, no climate controls in the back.

Recirculate would not stay on in any scenario when the system was in "AUTO" mode.

A/C could be turned on or off in "AUTO" mode.

Re-circ.. of course... could be used while not in "AUTO" mode.

Hope this helps.

Thanks for your reply. That helped a lot. I didn't know I was supposed to disengage 'AUTO' first. I feel a bit dumb.

Yes. Mine turned out to be the same.

My 'Re-Circ' only stay engaged, when 'AUTO' is turned off, "A/C" and "Re-Circ" is turned on.

But, 'Re-Circ' does not stay engaged, when 'AUTO' and 'A/C' is off, and only 'Re-Circ' is turned on. (wierd?)

Well, I now feel better, and it's most likely working then.

BTW, does anyone know of any sequence of sort for the climate unit to run diagnostic and display any error codes?
