The 1999 Oldsmobile Alero does not have Freon in the A/C system. It contains R134 and not Freon which is R12. As I am sure you do not have the proper equipment to recharge the system plus the fact it is illegal to add refrigerant to a system with a leak, until the leak is repaired, take it to a professional and have the leak repaired. You have a leak or you would not need to add refrigerant.
To add refrigerant to a Dodge Dakota find the suction hose of the A/C system. On the suction hose locate the port to add more refrigerant to the system.
134a refrigerant
Many home AC units are sealed, and there is no way for a homeowner to add refrigerant.

You add refrigerant at the low pressure port but you do not add Freon. You add R134/134a. If you are having to add refrigerant then you have a leak that needs to be repaired first.
Look under the hood and the is a label with the capacity printed on it. It is very critical to add the correct amount. A little extra is NOT good.
You can add Freon to your 1999 Chevrolet S 10 pickup truck cooling system, through the air conditioning compressor ports. The ports are located on the top of the compressor. You would add r134 refrigerant through the low pressure port located on the accumulator/dryer.
If you are having to add refrigerant, then this means you have a leak, and you will be adding refrigerant again in a few months. It is illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to take it to a professional and have the leak repaired and refrigerant added with the proper equipment, which you do not have.
