HELP WITH MY A/C!

[milehighhero]

I got into my truck today and all of the sudden my A/C wouldn't work. It would blow air but it wasnt cold, I bought refrigerant and the pump said that it was mechanical problems, anyone know what this could be?

does the compressor cycle on/off rapidly, or not at all? it could be a loose wire, fried clutch, bad compressor, pressure switch, clogged filter/drier......

it doesn't come on at all, we know that its not the relay. The blue light on the AC button inside the truck doesn't come on either.

Did you check the fuse? It has to be electrical from what you described.

Checked the fuse and it was good, i checked the relay. There are relays right above the fuse's, what are those for? There is also a relay on the front drivers side corner under the hood what is that one for?
