No leaks - AC system works great when the 2 heater hoses are disconnected from heater core.

just in case this helps anyone, I was able to achieve 43 degrees out the vents after i bypassed the heater core. its 90 degrees outside here. I'm thinking about leaving it this way for the summer

Howdy, As the title states I am not getting nice cold air out of the vents. I measured vent temps and they are almost 70 degrees. On a 93 Degree day here in Texas. Today I decided to evacuate the system, pull a vacuum that held , and then recharge to the correct amount of 21oz. Vent temps are still @ 70 degrees (85 degrees outside). The Low side pressure is 35 and High side is 192. The AC line going to evaporator is cold to the touch and sweating. I did change the airflow from defrost to floor and those work ok - but it didn't get colder, The heat works great too. Not sure how to tell if it is a blend door issue. Has anyone blocked off the heater core? thanks for any suggestions.
