1995 4Runner A/C compressor engaging but no cold air

Hey there!
About 5 months ago I replaced the entire A/C system in my 95 4Runner, and it blew ice cold air and had no leaks. Fast forward to a few weeks ago I turn on my A/C and the light comes on and the compressor engages, but no cold air. I have checked for leaks and have found nothing. Any ideas?

 

Entire with a new expansion valve?

 

Are you sure whatever controls the temperature/blend door is working properly?

 

I replaced the expansion valve- I didn’t think to check the blend door! I will look into that. Thank you both!

 

Update: found a small leak from the condenser. Thank you all for your help!
