Can't turn off A/C with fan on

yea you can, I believe you can still turn the A/C off with the temp control in the "max" position. The whole point though is that when you turn the blower on with the temp control in that position it automatically reverts to keeping the A/C on with recirculation. Convenient in the summer perhaps, frustrating at other times. Not a big deal to me, but takes more to get me agitated

 

Just re tested mine and it didn't kick on recirculation. Turned off recirculation turned truck off. Turned truck back on recirculation stayed off.


Maybe it's a 2011 and older thing. ?

All I wish is the damn lights didn't flicker like a short when I change speed settings

 

Agreed. There are MANY months out of the year where I just want to run vented air but as cool as possible. I don't want to go one 'tick' warmer to avoid turning on the A/C and this is a stupid design. If I want A/C the button is right there less than an inch away.. I'll turn it on myself. Tired of companies dumbing things down so the stupid customers can go 'Oh wow, I never thought that if I wanted the coldest possible air I should turn the heat mixer to the coldest setting plus the A/C & recirc buttons set to on' and so that people like me smart enough to figure that out have to deal with an inferior setup that won't do something simple and basic.

 

agreed!!

 

Mods?

 

Before you even get to max A/C the heat is off. The temperature is regulated by blending warm air to the A/C. if it's too cold warm air is blended into the system the A/C stays running. A/C is a dehumidifier and a damn good one by reducing the dew point frost is far less likely to form. There is not a modern vehicle out there today that does not turn on the A/C during defrost every one can't possibly be wrong.

 

If it's on the outside it's ice. If you run the A/C and the heat it will do a far better job clearing the glass. The engine makes far more heat that the A/C can overcome if you turn up the temp the A/C can not even come close to more than the 600 thousand BTU's the engine can produce in an hour. Try it some time hold your hand over the vents and see if you feel any cold air with the heat on. By doing so you heat and dehumidify at the same time good plan for moist air

 

No.

 

Uh, wut? You're not going to get heat out a cold engine...

Clearly everyone here is A/C experts. The A/C coming on on defrost is normal. A/C is a dehumidifier. When you defrost your window (ice situation), you will get fog built up on the inside. Fog is humidity. A/C DEHUMIDIFIES (dries) that fog. I am certain Toyota and everything other car manufacturer didn't overlook this. They pay highly skilled engineers to figure this stuff out. Yes, A/C creates colder air, but it also dries the air, which you want when you're defrosting.

 

I'm not arguing that. I want the ability to turn my vents on on the coldest setting w/o air or recirculation on.

 

That's a sounds argument. I guess the pros outweigh cons when it comes to whether or not it should be automatic or not.

 

Some things are nice to automate. Some things are more annoying than helpful. This falls into the latter category IMO.

 

I agree. This probably falls under a safety concern as people likely don't think that A/C would help in a defrost situation. Unfortunately, we live in a world where people can't think for themselves thus causing manufacturers to do these things.

 

ROFL

 

Maybe your car didn't come with it, but that doesn't mean manufacturers aren't "improving" their cars to include these "features". Lets take the car Google is working on. It drives itself, getting rid of that skinny pedal and all that.
Then we have Volvo and Mercedes, with cars that stop themselves before hitting the vehicle in front. I know there are doors where you have to pull the handle twice to get out if it is locked, once to unlock and another time to open it.

As for the radio auto muting when an emergency vehicle is around.... To be honest that actually is a good idea. I've found myself not hearing an emergency vehicle until it is right behind me, with all the noise dampening in cars now.

So with all that said, times are changing. I'm not saying I like all these features either, but with lawsuit happy people these days I think manufacturers are trying to cover their a$$es more by combining features and making them "automatic" for the lazy or uneducated. For those of us who do know how to operate all these controls for different situations, we have to suffer or find "mods" to regain full control. I wonder if people complained this much when the automatic transmission was created?

Anyway..enough ranting. We just have to make sure that people share these mods on how to un-automate things that the manufactures think the majority of customers want, who may or maynot understand the principles behind what they are doing.

I want to thank those who figure out how to make the controls work the way you prefer. Not everyone may want total control and its alot harder to automate something, than it is to un-automate it. While I did think the Max A/C was annoying at first coming from a 94 Landcruiser...it really hasn't bothered me much because it allows me to cycle the A/C and not sieze up later on, when it hasn't been used in a while.

 

Bottom line it is not a design flaw the main reason some people hack up wiring etc. is because they don't like it and figure they are a hell of a lot smarter than the designers. By the way I don't know about your truck but when I start mine it is stone cold and the air inside is equally as cold as it is outside at that point you have two choices, get out and scrape the ice or let the engine warm up. Once it is warm the hot air collects moisture inside the vehicle and the window fogs up I turn on the defrost it goes away outside and inside too.
