A/C blows warm air, not cold at all

[wilthis]

No cold air at all. When I push the A/C button, it lights up, but no cold air. I don't hear anything kicking in under the hood, nor does the RPM change at all.Any ideasPS I checked the door/flap and its OK.Thanks

First thing I'd check is if the AC compressor clutch engages. If it does and it still doesn't get cold, then it might need to be recharged.If it doesn't, it could be an electrical problem, like a blown fuse, bad relay, something like that. It could also be that the system is completely unpressurized, it needs a certain minimum pressure before the clutch will engage.
