My AC was working fine on my way to work. After work, I started my car and the AC was just blowing warm air. No warnings or error messages, just loud clicking. Seems like the noise is coming from a pulley by the engine. Any ideas? Just got new tires put on last week. Could soemthing have happened to the pulley when the new tires were being put on? I would appreciate any help in this matter. Thanks

sounds like a bad compressor or pulley

The pulley looks like its moving around. Could a bolt or screw have come loose? I live about an hour from the repair shop. Think I'd be safe driving it there?
