Hey everyone, as the weather is getting warmer I’ve started to turn the AC on but have noticed that even after 20-30 mins of driving it doesn’t blow very cold. A few notes; this is my first warm season with the Outback, outside temp is roughly 20 degrees C (68 F), have it turned to the lowest setting, and on full auto.

Ideally I’d like to get this solved before summer rolls around, but I’d like to see if I can figure out the issue before paying someone an hour of labour to tell me what’s wrong.

I’ve seen a few similar threads but most of them involve sounds or uneven air distribution that I am not experiencing. Also, if anyone has experience with getting this sort of problem diagnosed/fixed and knows roughly how much I can expect to spend that would be great! I’d love if it was something that I can fix myself, I’m not afraid to attempt to recharge it myself if that’s what it needs or do a coolant change, but I don’t want to do anything redundant.

Thanks!

Is your vehicle still under the 3year 36,000 mile warranty period? If so this should be covered.

I don’t think so. It was originally purchased at the end of 2017 putting it just outside of 3 years

mileage?

here are some simple test to do with the A/C off and recirc off

turn fan on to position 2 (manual) or 2 segments (auto)
start with the temp knob and go from cold to full hot and does the temp change coming out of the vents?
use each mode and does the air flow change accordingly.

doing the above will rule out actuators and blend doors not working

finally turn on A/C do you notice the engine load up a bit? if not, start there

Thanks! I will try this. And mileage is just under 37000 miles (under 60,000km in Canada. Which is the limit for 3 yr warranty)

^ still worth asking SOA (Canada) for assistance
Yes, I’ve got my car booked in for Monday for them to fix an oil leak (they said it’s under warranty), so I’m going to mention this and maybe it’ll be under warranty as well

Update: did the tests noted by @YeuEmMaiMai and the temperature gets warmer when knob is twisted, becomes stronger when fan strength is increased, and comes out of proper vents when those are toggled. However there was no audible (or temp) change when I turned on AC. I did the easy step and checked the fuse which appeared to be fine. I have an appointment with the dealer for an unrelated issue on Monday so I will at least ask them what they can do for me regarding this.

yeah hopefully it is just a relay. I am at 250Kkms and A/C is ice cold in the 2010 3.6R I do not have access to a 15+ service manual so I cannot tell you were the relay is

Thanks for all the help. I emailed Subaru Canada and I will see what my local dealership says when I bring it on Monday

Start test by using Auto, instead of Full Auto, which is all over the place. Sometimes Full Auto is blowing just lower, sometimes upper and lower, sometimes level 5 fan, sometimes level 1 fan, sometimes defrost, etc. Such variation is great for air regulation but is bad for testing the A/C. I find my Full Auto rarely blows much air in my face like traditional HVAC units. However, Subaru's Full Auto somehow gets to the requested temp with low humidity and stays there. Somebody on this site convinced my to leave the HVAC on Full Auto, and that's what I do now.

Update in case anyone is interested: had an appointment with Subaru this week for an engine related warranty fix so I asked if they’d check out my AC as well. They confirmed that there was a leak somewhere in the system however their diagnostic tool wasn’t working properly so there could not confirm where.
My next move is to get in touch with the Hyundai dealership that I bought it from just over a month ago and see what they can do for me. I called them last week, while I was still within 4 weeks of purchase, to inform them of the issue and that I would have Subaru check it out while it was there. I hope they’re easy to work with and cover the cost of this fix for me. I feel stupid for not noticing when I bought it, but it was before the warm weather hit here so as far as I could tell it was blowing cold. The first warm day I turned on the AC and got hit in the face with warm air. Hopefully I won’t have to pay out of pocket for this.

Not your fault... If it is 60 F or less inside the car, I don’t see how it is even possible to get the HVAC to blow out cold AC air from the face vents.

I just hope Hyundai will do the right thing and cover the fix. The Subaru service guy told me it could be hundreds or thousands depending on where the leak is so it’s in my best interest to do everything I can to have them pay for it.

Another update: I spoke with the Hyundai dealership today and they told me that they would cover the AC diagnosis fee with Subaru and once it is diagnosed they will most likely cover the fix as long as it’s not something that was obviously my fault, which I don’t think that’s possible with the driving I’ve been doing

as long as the HVAC senses outside temp above 32F it can function.. I tested my A/C when ti was 45F outside and it turned the compressor on in defrost mode

Me too, but I am talking about the face vents. In a cold environment, I don’t see how it is possible to test the AC at the face vents by just using your senses alone. My point is, the original poster is blaming himself for failing to do an impossible task.

Without a clutch on the compressor any more it is tough to tell when the compressor is actually on. Not as easy to do a quick check as it used to be.
