A/C BLOWING HEATER HOT AIR

1995 GMC C1500 • 154,000 miles

I have a 95 GMC Sierra Z-71 I turn the a/c on and it's like I have the heat on. The system is full of freon and it's even hot when it's off any ideas?

Does the temp slider feel like its moving the temp blend door?Does the temp change when moving the temp adjustment from cold to hot and hot to cold?

I can hear the damper open and close when I turn it from cold to hot

So does it actually feel like the heat is on all the time being that hot?Or is it just warm air?
