My air conditioner does not blow cool, what could be wrong?

Either low on R134 refrigerant gas or the clutch on compressor not engaging. To check the clutch, open the hood, turn on A/C full blast, and the part on the end of the compressor should be turning. See the end part by the ribbed pulley? Ok, the pulley will always be turning, driven by the belt. But if the very end part, that is the clutch, is not also spinning then for some reason it is not being engaged. If it is turning with the rest of the pulley, you probably low on refrigerant gas, that can be done yourself with a kit, follow instructions that come with it, but first check for leaks so you don't waste a can of R134.

I put refrigerant in it the clutch won't engage I turn it on the fans don't come on but I tested the fans there they run good I've checked the relays they seem to be good I just don't know what else to try any ideas
