I recently bought an a/c compressor online for my 2004 Nissan Altima. The shop replaced my old a/c compressor and the a/c worked fine but the belt always screeched when I started the car. I took it back in and they fixed the belt problem but now I cant get any cold air. Everything sounds fine under the hood but I cant get any cold air. Whats the problem? Please help!
