On the 4 cyl. altimas (without climate control), the heating and aircond. controls do not allow you to recirculate air when air is directed at your feet only or when defrosting. This seems to be some sort of electronic logic, not mechanical. Does anyone have any clue has this can be defeated so that I can make my own decsions about this?

I don't think is strictly for the 2.5 models - I have a 3.5 model - if you put the air towards the windshield it automatically grabs air from the outside. Assuming you want to equate the temperature inside on the glass with the temperature outside to get rid of the foggy winshield - so therefore you would not want to recirculate. As far as the air coming on your toes - I thik I can hit the recirculate button when I chose this... I do have auto climate though...

Hmm, anyone else care to chime in who has a 3.5SE without auto climate control?

Yeah, the recirculate button only works on certain settings for me. If that's what you where asking.

On my three current Japanese cars I can recirculate whenever I choose to. You can defrost quite well with the air recirculating and the A/C on (to de-humidify). Under some conditions when the outside air is dusty or you are in a tunnel etc. I prefer doing this. Having this choice is one of the reasons I abandoned buying american cars years ago. Nissan is going backwards.

for me, recirculate doesn't work in the following settings:

defrost

heat&defrost.


works on all other settings. the reasoning is mainly a safety issue. They don't want you to possibly fog up the inside of the winshield by defrosting without bringing in fresh outside air.

I think domestics had the right idea...

Unfortunately I will have to say that the domestics might have the right idea and Nissan may be going in the right direction with directing the outside air to the windshield when that is chosen.

I think of my dad for example - who owns a 1994 Honda Accord - purchased it new. To this day when it rains he still has a hard time figuring out that he can get air from outside to the windshield and turn the A/C on to clear things up real quick.

When the temperature brings out the foggy windshield - it becomes dangerous driving with my father. In a Nissan if he figured to position the air to the windshield NISSAN will take care of the rest...

thanks nissan for taking care me....

Well I still disagree. with both (present model) Hondas and VWs when you switch to defrost, outside air comes in but the driver has to option (by pushing recirculate again) to override this. To me this is an example of Honda's and VW's attention to detail. This seems to be the best of both worlds. And can you tell me why you must have recirculating air in the Altima (4 cyl.) when air is directed downwards?

Downward Recirculation

Sure, I can tell you why it doesn't work...

When you choose to blow air at you feet, the inlet for the recirculation is right next to the lower outlet. The only thing that would happen is the air would come out of the lower outlet and go back into the recirculation inlet.

As for the defrost (or upper) outlet, that issue has been discussed. Nissan is not letting you do something that would really not be a good idea to do anyway.

Thanks all for the philosophical discussions about recirculating air. I had asked the question; Does anyone know how to defeat the interlock? Guess the answer is no.
And for all you Nissan worshipers (who believe Nissan knows best); With the climate control on the leather SE, you can recirculate air with the air directed downward and with the air directed down and towards defrost. Oh my god! Why would Nissan ever allow that?!!
