My AC is working intermittently. Blows warm air and the snowflake icon blinks. Had the system charged last summer when it started but didn't help. The clutch would engage & cycle, but the air wouldn't cool. That was last summer. Now, the clutch isn't engaging - yet last week it did.
Any ideas out there if I'm dealing with a dead compressor or pressure switches?

 

Update; once the ambient temp warmed up, the clutch is engaging and the cooling fans come on, but the temp is luke warm with 18deg C selected (the lowest it goes).
I'm wondering now if it might be the temp sensor for the dual climate control - ie it's sensing a cooler temp than actual so not asking the AC for any cooler. Any thoughts out there on this? Anyone know where these sensors are located?
Thanks in advance.

 

I have a similar issue with flashing Snowflake on 2014 outlander. Also very interested in fix. Was ice cold a week ago no flashing light but now snow flake flashes. My compressor works, clutch engages, fan cycles. I just replaced the filthy/partially clogged cabin air filter and it worked better for a little while now. It works from time to time but when that snowflake flashes it just stops blowing cold air. Push the button again and flashing stops and I get cold air for a bit than goes back to warm air. This is while driving and idling.

 

It's a bit of a mystery still. I have picked up some gauges to test my compressor output and will update when I have those results. For me, the system either isn't able to cool properly or the sensors think it's cool enough. I'm hoping it's not the compressor....
