My climate control was working just fine yesterday, but today I have no air conditioning. When I set the climate control to warm temperatures I get heat, and when it's on cold temperatures I only get outside air blowing in with no air conditioning. When the vents are set to windshield defrost (the button on the far left) it only blows hot air regardless of the temperature setting of the climate control (is this normal? I hadn't noticed this until now.) I checked the Poly V belt and it's fine; it seems that the A/C compressor just doesn't engage. The fan(s) that usually turn on when the A/C is running don't come on at all.

In my car the moment i turn the air blower switch the AC compressor use to engage. The question is this nrmal? But now as mentioned above the AC compressor is not engaging. The freuon gas is ok.

Any ideas as to what may have gone wrong? I've search this forum but was unsuccessful in finding info on this problem. I would appreciate any help I can get before I start poking around under the hood tonight.
