I have a 2003 Grand Prix GT and the AC recharge port is right behind the motor on the firewall. Look for the silver pipes coming out of the firewall right near the middle. You will see the recharge port on one of the pipes there.
Using the proper type of freon and a gauge, connect to the low side ac port. With the engine running and the ac on high, add freon till the gauge shows full.
If the system is empty you have a leak. If you try to recharge it yourself it won't last for long. Take it to a AC specialist and get it over with. If you must give it a try go to your local auto parts store and purchase a recharge kit. The kit will come with directions. Remember it is illegal to release refrigerant into the atmosphere.
Was unit evacuated before recharge after compressor replacement?
You can recharge your 2003 Kia air conditioning system through the low pressure port. Connect your Freon bottle to the low pressure port. Release the Freon into the system.
