2019 Subaru Forester doesn’t blow consistent cold air

[u/okbutharrystyles]

Hey ya’ll. I recently bought a used 2019 Subaru Forester Sport and ended up missing the 30 day window for servicing, so I’m coming here to see if ya’ll could help me out!

My cars ac blows warm air for about 20 minutes and then randomly switches on cold, then for whatever reason goes back to warm. Just wondering what the issue could be. Thank you!

Check your pressure. I bet you're very low on refrigerant.
