may have a freon leak. Happens even in new cars. The dealer will be able to test the temperature and pressure check the system.

Do yourself a favor and buy a $10 thermometer like this one:
Amazon.com: CDN IRXL220 ProAccurate Insta-Read NSF Large Dial Professional: Kitchen & Dining
and get your own temperature reading before going in the dealer. Stick it in a center duct with the AC on and it should read about 40 degrees F within a couple minutes.

That'll save you at least one trip to the dealer since your first trip they'll just tell you nothing is wrong; that's how it is; don't worry.

PS Be sure to check the thermometer accuracy using a glass of ice water. Only takes about 30 seconds to do. The type of thermometer I linked to can be adjusted/calibrated, plus it has no batteries to ever replace. Useful in the kitchen as well.

I’ve had experience with this, and I agree with clutch5. Putting a thermometer right at a duct should read 40 degrees. If it’s anything higher take your car to the dealer.

Just print this thread and bring it with you. Dealer SA usually won't BS a forum member who did his/her homework because they fear being bashed.

They should be able to replace it, considering our AC is meant to freeze our a**es off!

Like everyone else, both of my 2nd gens have extremely good, cold AC.
I don't think you need to get a thermometer. If the dealer tries to tell you yours is normal then all he has to do is prove it by demonstrating it in one of the many others he has on the lot.
The outdoor climate will have an effect on the automatic fan speed which will have an effect on how it feels in the cabin.

Instead of creating new thread I figured I’d use this old one.

My Air isn’t cold, no idea where to start troubleshooting at. Tried to fill with Freon and it seems like it will never fill up under hood. Everything was good until I had my radiator and thermostat replaced. Random I know but a/c went out shortly after that... any pointers other than dealer
