Heat and recirculate at same time?
 

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! :fdance:

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

Re: Heat and recirculate at same time?
 

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.

Re: Heat and recirculate at same time?
 

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.

Re: Heat and recirculate at same time?
 

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?
