You can get a kit at auto supply for diy. R134A refrigerant, it should come with some directions. --- follow the larger of the lines from your comp. till you come to a quick disconnect fitting, proly has a cover on it. Start the engine, idle, turn a/c on high. Look out for fan blades and moving parts and connect the fill kit connector to fitting. There is a gage on fill kit, slowly open the valve till the gages shows some movement, keep charge can upright. The gage may go up, operate valve to keep pressure below 50 psi. The compressor will start as soon as the pressure is sufficient. Open or close the valve as needed to keep below 50psi, continue and the pressure will begin to drop as charge builds up ,when it reaches 30 psi you are done. close the valve, disconnect fitting. Be sure engine is idling, a/c on before connecting as the pressure could be 100 psi or more with engine off.

Basically the refrigerant is dispensed via the low pressure valve. BUT it is not something you want to do. Very very high chance of messing up or making it no better than it was. It is not as simple as put more in. If the level went low it might be a leak. The best and only decent way is to use a machine to recharge your AC because it will evacuate the system completely, pressure test for leaks, refill with refrigerant and lubricating oil to the correct qauntities. Oh and it will dispose collect the old refrigerant which shouldnt be vented to the air.
The machine is expensive to buy but most garages and AC service shops have them and will do the recharge for you at a reasonable cost.

Breeze1,
First off, please (w/ all due respect to them) IGNORE what these others have posted.
An A/C system is a very HIGH pressure system. Thus it is a VERY DANGEROUS system to work on. You NEED to know what you're doing, or back pressure can cause a can of refrigerant to literally explode.
Since you need to be holding (shaking the can) while it's charging the system, that could be VERY harazdous.
Please, if you've never worked on an A/C system, have a professional do it.
I have roughly 15 years background in the car business, and know A/C systems can be dangerous, while most other systems are fun for "backyard" mechanics to work on...an A/C unit isn't one of them!
P.S. Tronary's post wasn't up when I started typing this response!!!

Check all your fuses,check the wire plug going to the compressor,if thats not the problem,your screwed(just kidding)go to walmart or autozone and get a can off freon,follow the instructions on the can

i dont know all the details here but it may be an ac compressor clutch, or a componant such as a wire or relay for the clutch. not too sure i was never good with ac. but if you look at the refrigerant line you should find a valve for recharging.

Read the owner's manual that came with your truck. It will tell you how and where to put it in.
If you don't have an owner's manual, take it to the mechanic and ask him to put it in for you.
