Jeep Cherokee Forum - AC blowing no air at all after changing evaporator.

hi everyone.
I am having a problem with my AC, I just had the whole dashboard pulled out and the HVAC box opened to change the AC evaporator and the heater coil. Some how the vacuume lines were disconnected and I didn't have a picture of them and their setting before they get disconnected, so they were reconnected by the technician to the best of his memory.
after putting back everything and the dashboard is back in place, I discovered that no air is coming out from any of the vents, not the foot, nor the front, and not even the windshield vents, nothing, the fan is running, you can hear it, but no air at all.
also the vacuum line in the engin bay next to the pipes of the AC evaporator and heater coil was torn during the process and was repaired.
does anyone have a picture of the color coded setting of the vacuum lines in the HVAC box?
any tips or suggestions on what to do other than changing the terrible technician who did this disaster?
