The 2002 caravan ac should be charged at the low pressure service port. This port is located on the suction line near the compressor. The suction line can be identified by it's size, it being the larger of the two line connected to the compressor. You must purchase a recharge kit at your local part store, which should include charging hose with pressure gauge and a can of R134a freon. Gloves and eye protection should be worn during servicing.(freon can freeze your eyes and cause frost bite to your hands). Connect freon to charging hose, connect charging hose to low pressure service port, open valves and start engine, turn on ac. If compressor won't start it may be required to disconnect the low pressure switch and jump out the connector.
