My A/C isn't blowing cold air, just blowing air. Doesn't work at defrost either to blow cold air. When I change the temp to hot, it blows hot. And all through this, the A/C motor is loud. Bad A/C, no coolant, or both?

The easy way to find the problem is take it to a shop near me that does free A/C checks, but I'm sure they'll try the hard sell when I find out what's wrong. And not having A/C isn't killing me, since I use the car for newspaper delivery. I only need the A/C when I'm done folding and I'm trying to cool down.
