Might also be a stuck heater control valve as well.

Think i found it got some acpro now shot some in to it got to 35psi waited 5minutes it droped back down to 25psi now if i had a bad leak like that i would see a small cloud of white i think it was just that low.So going to.check it everyday for 2 days if it holds at 25psi then it was low low on freon.

If you have a traditional heater control valve it will be located near where the heater lines enter the firewall. Things have changed and since I am not familiar with the Trailblazer
its possible that its elsewhere. Might want to make sure that your heater/AC actuators are working properly as well.

At 80 F and depending on humidity, 35-40 PSI on the low side is normal. High side should be at 175-210 PSI depending on the system. Do you have access to an A/C gauge set? Also a can of leak detector dye might be a good idea. Outlet temps on a good system will be 45 F or less.
