Does your A/C go to auto after like 30 min of driving? at like 78-80 ?
Mine does, it is annoying.

 

on my 05 max when i have my heat on for a little while the ac button will light up by it self i took my car to the dealer and they said there was nothing wrong wiht ti it is sopose to do that

 

um, 78-80 mph or k/h or dregrees? does the auto come on, or the ac? not very clear what you're asking. anymay...

AUTO means the car knows what's best. leave it be. AC is supposed to be on year round.

look at old threads to read why.

 

I can not search( it won't let me), can someone post links? or the reason why?
Thanks

 

Yes, mine does the same. I believe it helps with the humidity levels inside the car along with temp control. I would do same thing when I first got the car but now just let the auto do its thing.

 

It helps stop the windows from fogging up. Extra cold outside+warm to hot inside=extra fogged up windows. AC running helps prevent that.

 

Seriously, the climate control has a mind of it's own. It gives you buttons that make you 'feel' comfortable...for all the wrong reasons. :-P

 

Only reason i hate when the A/c comes on is the fact of possible extra gas consumption and the car takes alil power hit. but other than that the auto is doing just that auto adjusting for the temp.

 

Thats normal dude.. suppose to set a comfortable climate control or some ****..

 

yes you can. read through the Stickies to find out how.

who said you can't browse the thread titles on each page?

We don't need 100 threads on the same topic because no one wants to look up the info. What takes longer, you spending 15 minutes to skim the thread titles, or waiting 3 days until someone feels like answering your question? Many so-called "urgent" questions are answered by the manual, or a quick phone call to the dealer.

This site is NOT a dedicated maxima user support technical team. The majority of this community enjoys helping each other out. But I also see a good majority that likes to help others help themselves and not see the same topic posted 100 times.

 

bro...that whole extra gas thing is about as accurate as a myth...driving with your windows down consumes more gas than an ac....

 

logik is logical . . I mean logik is correct. One open window affects gas mileage more than having the AC on.

AC systems are a lot more efficient than they were thirty years ago.

 

My car does it also. I agree with the guys that are telling it is for defogging. The ac really does not make your car too much more gas. Just like they said driving with one or more wiondows down will burn more gas. With the windows open you essentially make your car into are parachute. The car is being held back by the wind that gets to your back window causing you to give the car more gas to keep up with speed. It is normal your car is just tring to help with keeping the windows clear. It is a bit confussing if you don't know that the ac is like a defogger. I was the same way until I found out it was normal.

but driving with the a/c when its 10degrees outside sucks! get my drift now.

 

I know this is getting offtopic but lightonthehill i have the up most respect for you but i think i may have you here. I know it sounds very logical that a/c on is much better than open windows with wind resistance and all. But i was watching mythbusters and they had two 2005 ford explorers identcial in everyway. They ran them around a track one with a/c on and the other with the window down. They aswell thought the a/c would conserve more gas. But in the end the Explorer with the windows down did an extra 35miles or so extra over the explorer with the a/c on. They also had all kinds of computer sytstems hooked up to the cars and everything was confirmed, just to make sure there wasnt any kind of mechanical advantage. After watching that i was pretty much convinced that windows down works better.

But in the end i was just comparing my answer to the original question of the thread. The gentalmen was saying his a/c kicks on when its cold outside, and i agreed it did and i just simply turn it off unless i see my windows fogging up alot. And the main reason i shut it off is just to keep some of that power.

 

I saw the one with the silver F150's but that discussed tailgate open or closed on the highway, are you sure it was an Explorer?

I also heard that the most efficient way to drive is with no A/C on and windows closed, followed by A/C on and then by windows open. Another thing with the Auto function is that it changes the vents that it uses as well as turning on the A/C. It will go from using all defroster to just the feet. I choose the dash vents and feet vents and a few minutes later its changed to what the computer thinks is best but that usually isn't what I wanted. I've pretty much given up on the auto and I'll do it myself.

 

Myth-busters used "Ford trucks" we have a bit less drag and better gas mileage, so I don't think their study has any relevance to us. Plus it's Ford engineering compared to Nissan.

Fine, turn your AC off in the winter. Just don't use Auto. but please don't make another thread about "my windows keep fogging up" AC dries the air.

If you're running at a low fan speed, the AC isn't working hard at all to affect your gas. Transversely, you'll probably use more gas with the fan on full blast and no AC. You better not use the defroster, heated seats, or wheel if you're so concerned about gas mileage. Oh and drive 5mph under the speed limit.

Only negative I've seen from AC year-round, check your coolant level. After a year, my reservoir was empty. I always use AUTO, but if I have gas saving on my mind, and the cabin's already comfortable, I'll either shut it off and open the vents, or reduce the speed to 2-3 bars.

 

Not that it this tread should not just die, but the AC on is the AC on it matters not the fan speed the ac compressor adds the same load.

 

Just to throw some more info into the mix here....since its already been discussed to death before...once the AC compressor is turned on it doesn't shut off till the ignition is turned off again. The light goes out on the dash but the compressor is still turning.

It wasnt Explorer either it was a Ford Expedition.


Any how i see tempers are about to flare over the A/C so ill leave this subject alone. I guess people should do what they feel comfortbale. And for me AC during the winter does not come on at all. Because you can keep ur car in auto without the AC on and it still defogs properly, and yes i know ac does it quicker.
