AC problem

I just had my battery, belt and alternator replaced and now the ac doesnt blow cold air!! Any thoughts on what could be wrong??

It's hard to say. Did they forget to put the A/C belt on? Any thing is possible. If that is not the case, then checking for system pressure and power at the compressor is the first place to start.

It could also be that they didn't get the belt tight enough or the electrical connector may be off or loose. Open the hood and have someone turn on the AC and see if the compressor starts. If it doesn't start check for an electrical connection that may have come loose from the compressor.
