2002 a/c. Blows hot then cold

Looking for your thoughts. My ac does not always cool. It blows cool air, then switches and blows hot air, then switches back to cold.

Last year I replaced the expansion valve and dryer and had system recharged, trying to fix this problem.
Thank you for any suggestions.

Problem with the blend doors in the HVAC console?

Dutch, that’s a great idea. Is that located behind the center dash console? It seems like the air flow is also restricted.

Thanks

Yes. The levers that control those doors have been known to break. It's been discussed here.
