AC Not Cold Due to Refrigerant Leak on GMC Safari

Problem Description and Possible Solution

On vans with rear AC, the AC may stop blowing cold air due to a damaged AC line near the back of the engine. It is common for these lines to rub on the engine block, causing a hole in the line and a refrigerant leak.

I am unable to get cool air from the back cooling unit. I bought this van Dec. 2014. I have started my parts replacement program 5 weeks ago.
Rear evaporator coil not draining properly.
Does anyone have the best way to clean bottom of pan without taking evaporator out?
