I recently replaced the AC condenser on my '03 ES. I recharged and the air is not getting cold. I did not vacuum the air out and I am aware that this is the problem. I need advice on what I need to do, I have never worked on an AC before. I am looking at purchasing a vacuum pump. Do I need to empty the refrigerant that is in the system then vacuum and recharge? Where can I get a decent vacuum pump for a good price? Thanks for your help.
