So, this code is actually 1264 and not 12 and 64 as this is the EATC self-test that gives these codes.
I am attaching the testing for this code, but this is for the floor vent and is not going to cause the A/C to blow warm.
This is going to be a freon related issue.
So that means we need to start with checking the pressures on the system.
Here is a guide that will help with doing this:

I am attaching a chart below that will help with determining possible causes of this but let's start here and see what the pressures are when the engine is on, and the A/C is running.
Thanks
