1st post, welcome. You might have one of several items going on with the AC. The very first and easiest thing to check is to see if you're low on refrigerant. C5s have weird things happen when the coolant is low. Also, you might have blend door issues. Those are addressed in many threads. Finally, have you pulled your codes to see if any codes are being thrown? If you know how to great. If not, here's a brief tutorial on pulling your codes. Reply back and let us know what you find.

Check the serpentine belt, AC compressor pulley may be slipping at higher rpm.

That's usually a sign of low refrigerant.
