Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

You may have a couple different issues going on and it's going to require some testing to determine exactly what is wrong. You may have a blend door issue but it may not be blowing cold due to an issue with the a/c system.

Are you able to change temperature at all?

Does it change modes correctly?

Have you checked to see if the a/c compressor is engaging?
