First off, it does not contain Freon. Freon is R12 and your Hummer contains R134a which is not Freon. This is not a DIY job. If it is low of refrigerant then it has a leak, and it is illegal to add refrigerant without repairing the leak. I suggest you take the vehicle to a professional that has the expertise and special tools to accomplish this repair.
First, your 1998 Mercury contains no Freon which is R12. It contains R-134 refrigerant. You add R134 at the low pressure port. But the fact that you need to add R134 indicates you have a leak. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Seek professional help and have the leak repaired.
Refrigerant goes in the lower pressure hose on a vehicle. The lower pressure hose can be found on the right side of the engine.
