The AC recharge port on a 2004 GMC envoy is on the low pressure connection. It is the larger of two hoses near the firewall.
you will have to take it in to have it serviced because of the r-12 coolant. ask about possibly flushing it out and updating it with 134. unfortunately, the ac process, either one, is not a cheap one...
Take it to a garage that services ac. If it needs a recharge it must have a leak in the system.
take it to a dealer.

To recharge the AC on a 1996 GMC Jimmy, first, locate the low-pressure service port, which is typically near the accumulator or the compressor. Attach the refrigerant can with a gauge to the low-pressure port, ensuring the engine is running and the AC is set to the maximum cool setting. Start adding refrigerant slowly while monitoring the gauge to avoid overcharging. Once the pressure reaches the recommended level, detach the can and check for any leaks or issues.

To change the low port on a 1999 GMC Jimmy, first, ensure the vehicle is turned off and the AC system is depressurized for safety. Locate the low-pressure service port, typically found on the larger AC line near the compressor. Use a wrench to disconnect the service port cap, then replace the port or any damaged components as needed. Finally, reattach the cap securely and recharge the AC system with the appropriate refrigerant.
The air pump or smog pump on a 99 GMC Jimmy is located right behind the bumper, below the radiator, and on the passenger side.
