You will need R134a, and a filler hose. Charge the system on the low pressure side, it should have a blue cap on the charge point.
Your filler hose will only fit the low pressure side, just in case the cap has been removed.

It sounds like the dual climate control valve. It is supposed to close the valves when the a/c is turned on, but they get stuck sometimes. I have already replaced 2.
What happens is the valves get stuck and the engine heat will blow over the cool air making it feel warm, even though the a/c is working fine.
If it started out on one side of the car cooling better than the other than you can almost bet this is the problem.
They will be called a heater control valve by most auto parts stores. I think the part is Motorcraft YG378.
Another way to make sure this is the problem is to find the dccv and clamp the two top black hoses with pliers or something and see if the car gets cooler. It will still not get cold but this will let you know if the dccv is the problem.
