There are two AC fuses #30 and #44. Did you check both of them with a meter? Or just visually?

Just visual. I Check just some one 10A the 40#
44# is it a fuse?

Sorry, #44 is a relay. However my owners manual (2003 Envoy) lists #30 not #40 as the AC fuse. #40 on mine is the HORN relay.

Also, some times the crack in the fuse can't be seen. You need to check using a meter or test light to be sure.

Empty AC systems often require a specialist. Almost nobody has the tools to fix it themselves.
