Sube AC ?

Only if the engine is running hot/under too much load and in danger of overheating. I drive a 1999 Subaru Forester, and have had that happen only when offroad this summer and climbing *really* steep hills.

I THINK my wife's Outback does - but maybe in ECONO mode only? The manual is vague in that section.

what is ECONO mode?

I have a vacuum cutout switch I would like to install if it doesn't do it and I can figure where to. Great little item. I thought all cars would have them now.

From the serv. manual for the 03 outback:

"When the ECM receives a full-throttle signal fromt he tps dur> Does Sube cut out the AC compressor when accelerating?

The wife's 03 OBW has a button that cycles through off-A/C-ECONO (also - if I hold it down for 3 or so seconds it alters the brightness of the climate display lights at night). My 06 WRX is different though.

Carl

Is that on the NA or turbo? Do you know if they are the same, or what they call it?

VF

Does the OBW have Climate Control?

VF

Econo mode is basically no AC compressor running. Usually on cars with climate control. That's how you get just untreated (un-AC'd, really) outside air, although frankly, on both of my CC-equiped cars, it doesn't seem like you're REALLY get totally untreated outside air.

It is called the compressor acceleration cut system.

There was no turbo > >

Yes, a sensor to measure the air temp, a solar sensor on the dash over on the right under the window. makes up it's own mind about turning the fan on full AFTER it warms up a little in the winter (so you don't get a blast of cold air up the pants I guess) swithches from recirculate to 'fresh' after the car cools down enough on warm days, etc. Of course, you can overide any of these manually. Seems my wife is never happy with the machine;s decisions while I rarely take it off 'auto'. Sometimes I will change it if I get interior windshield fogging.

The system in my WRX is a little trickier to manually control. But I rarely do so. Even on extremely hot days it works well (though i do have decent tint on the windows.)

I tried to cut/paste from the 03 OBW manual at

and did get the table of contents but it couldn't find any of the sections I clicked on. The A/C may cut out as you suggest - but still the difference between auto and econ is very unclear in the manual (Japlish I huess)

Carl

What i posted comes directly from the service manual, in the mechanical function, HVAC, Compressor Control section.

From the manual too:

AH - OK, that makes sense. THe OM makes no mention of use of the xtra sensor input.

I know my 91 5spd 2.2 Liberty did but only on full throttle. Not sure with our 99 O/B or more current range. Easy way to find out once it's broken in though :)

Haven't figured out if I can rev the motor from under the hood, Can't figure where much is yet((. Would be hard to tell if the AC cuts out when accelerating, unless looking at the clutch, or if the AC dash light goes off, but don't want to be looking at it while accelerating.))
