R55 Heat/Cool Auto Mode
Heat/Cool Auto Mode
When I put my Clubman into Auto Climate control mode to attempt to keep warm, The Air Conditioning LED always comes on and I have to turn it OFF.
Is this Normal?
Is there a way to put it in Auto and Not turn the Air on?
Just wondering in Indiana?

No, it's not normal.
I think it could be normal, as that was my experience with auto climate previously (93 Altima GLE). The concept (imo) of "full auto" includes humidity control, which indicates A/C would be active. I do turn the AC off if it's a dry day (no big deal, and you still get temp control), and also run fully manual heat often. It took me awhile to realize I had to run the system with no AC and the temp control lower than outside in order to simply get fresh air through the vents... those days are gone for a few months around here.
My Mini does this as well. Auto mode always turns on the A/C. Turning off the A/C by pressing the snowflake doesn't shut off the auto function. Same thing for a Camry my family has with auto climate control.
Seems normal to me.

I would not be surprised if it is normal.
If the control system is designed 'correctly' it would sense the humidity and then turn on the A/C as needed to control humidity. Then it would use the heater, if needed, to control the temperature.
Honestly, I haven't paid any attention to how ours works.

What it appears to me is this: Auto, as the OP says, includes both humidity control and the setting of the system to heat or cool to achieve the desired temperature. I always turn the AC off as well; but that lets the system direct the air through the vents that it "wants" for the temperature you're trying to achieve.
That's MINI climate control according to me.
Yes, in fact it was a feature requested by us Arizonans...

I've resigned myself to not think of it as A/C, it's actually just running the compressor, dehumidifying the cabin. Despite the light always being on, the compressor isn't necessarily running constantly, and I assume the management system cycles it as needed, just as it would for actual A/C.
Also as others have stated it also helps keep the fog off the windows when the interior of the car gets humid, i.e. when you are breathing.
No All my cars since 2000 have been this way. Some of my earlier cars did nto even have air conditioning so it did nto work that way on those.
It is normal for me ('08 MCS) as I have the same experience. It was also normal for my 04 Maxima. What I did was hit the Auto button, then press the snowflake to turn off the A/C. The climate control system still regulates the air temp, just without the A/C running. I can tell this because the fan speed will change as the temperature in the cabin normalizes, hence it is still regulating the temp in Auto mode. The only thing is that, if the temp gets high enough on the outside to where it can not keep the cabin cool, the fan will stay on high, trying to lower the temp, only blowing hot air. When that happens, I just push the snowflake again to kick the A/C on. But most of the time, now that it is cool outside, I can keep the A/C off. The MINI remembers this so I don't have to turn off the A/C every time I start the car.
Tomorrow, when it's already on "Auto," switch it out of auto by pushing one of the vent selection buttons on the right. Then push Auto again, and see if the light on the AC button comes on.
I rarely do anything with the Auto climate control other than adjust the temperature, so I guess the last time I saw the A/C light on was a couple of months ago when I last used the A/C.
It seems pretty wasteful to have the A/C compressor running regardless of the outside temperature, which is what the manual says happens when "Auto" is selected. For me, a better choice is to select the A/C only whren needed, so it's not running all the time for no reason.
That's why I rarely use the Auto setting. I just set the temp and let it go.
I have not figured out why there is an Auto setting. I can set a temp and the system will maintain that temp. The only differences (that I can tell) are that in Auto it will change the fan speed and kick on the AC compressor, neither of which I want to happen.

It is amazing to me that I can go from 50 degrees to 100+ degrees in an hour, and never notice it until I exit my Clubbie.

For instance if I drive from the base of Mount Wahsington N.H. on a summer day where the temp is 85 degrees i want the temp in the car at 70 degrees. by the time I get to the top of Mount Washington (a 7 mile drive) will need the heat on to keep the temp up to 70 degrees as it is now only 35-40 degrees outside. Now as i come back down the mountain the temp goes back up to 85 degrees and the auto climate control is now cooling the air rather than heating it. This function keeps me and my passangers comfotable to 70 degrees because it is "Auto Climate Control"
I start my commute in a notoriously humid environment, and end it in a notoriously dry environment. AUTO does exactly what it should along the way, causes no perceptible drag (compressor cycling) at highway speeds, and in my own tests does not impact mileage sufficiently to exclude it's use. I have to wonder if Sport Mode also suspends the compressor during heavy acceleration...I'll have to test this out.

I agree with you guys. I just don't see a need for it. When I want AC I turn it on, when I don't it stays off.
I guess it's one of those things that is automatic and doesn't need to be. I like manual controls on most things.
What I would rather have is a control for the floor vents where I can turn mine down and turn the passenger one up.

I have that in my 03 BMW and it is great. That would be a great feature.
Sweet !!!

So now I know that my Little Red Wagon is Normal.
After all the details of Humidity control it does make since.
Man ya gotta love the way everyone helps out with a question!
Thank you !!

How did you verify this?
Again the compressor will ONLY run when it is needed. This is how it work s on all cars with auto climate control. And also in real word test just this morning it checked tha compressor to see if it was running, and it was not when the temperature was down to 19F. Again the compressor only runs when it is needed, so there is no reason to have to turn it off.

Edit: I noticed that despite the heater being turned on (it got chilly here Friday, first time running the heater!), the glove box stayed refrigerated...I was surprised...and this is likely a benefit of leaving the compressor running in ACC mode, as I can't think of any other way to chill that space otherwise.

Ok, that makes sense. I can hear it going on and off at idle. I also think you are correct about the compressor going off under heavy acceleration. What you said jogged my memory. My 97 Saturn SC2 would shut off the compressor if I hit the gas hard. You could actually feel the acceleration improve when it did this. I would think (hope) that the MINI would be at least as smart as my old Saturn.
