I don't know much about ac but check to see if the compressor is engageing or not. It's the pully on the bottom drivers side you'll hear it and you can see it if you shine a flash light down there.

I can feel the power loss when I turn on the a/c, so I think the compressor is working. My a/c worked fine before I changed out the heater core. How do I check vacumn?
