You can add Freon to your 2005 Pontiac Grand Prix air conditioning system through the low pressure port. The low pressure port can be found on the air conditioner compressor.
The 2002 Dodge Grand Caravan air conditioning recharge valve is located on the air conditioning compressor. The recharge valve will be labeled as such.

Yes, there is an air conditioning relay on the 2001 Pontiac Grand Prix. The air conditioning relay is located in the fuse box underneath the hood.
BEHIND THE COMPRESER
It doesn't have one.
If it is a six cylinder the low pressure fill is on the passenger side near the firewall.
It is located on the pressure line.

Yes - it's commonly done to test the low pressure switch when diagnosing a defective AC system. However, this is not something you'd want to do as a means of cycling the compressor while you're driving - you could easily overpessurize and destroy the AC system.
you may have a cracked hose ***Your cooling system generally runs significantly hotter when the Air Conditioning is running. This is due to the extra heat produced by the A/C condenser located just in front of the radiator. You most likely have a defective radiator or cap, or a very small leak in your cooling system. The increased heat from the A/C causes increased pressure in the cooling system, and the leak becomes more evident.
