If the blower motor sounds different, like it isn't spinning as fast, I would start there. Check to see that it is getting proper power. The motor may be going bad.
As far as the AC, there is a single wire that goes to the compressor. When power is sent, an electric clutch engages and turns the compressor. Basically, if it isn't engaging, use a test light to see if there is power to the wire when the AC is turned on.
