How do you disconnect the discharge line from the A/C that connects to the condenseer??? I stuck one of those quick disconnect tools but its doing nothing!!!!
Make sure that there is no refrigerant left in the system before you attempt to disconnect any lines.
The hat shaped section goes on facing the large part of the coupling. Then you press hard on the brim until it forces the sleeve into the coupling and releases the spring. You may need someone to pull on the line while you press on the coupling. Put some refrigerant oil on them when you put the line back together.
