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.
