The air conditioner on a 2004 Saturn Vue is recharged by locating the low pressure valve and connecting the refrigerant supply. It is then injected into the system until the desired pressure is reached.
You will need a Freon recharge kit. Connect the hoses of the recharge kit to the ports on top of the air conditioner compressor. Release the Freon into the compressor.

The cabin air filter on the Saturn Vue is on the passanger side up on the firewall. I think there is like 3 or 4 screws to remove. It is on the upper flat part of the firewall.
