Phil,
Thanks for the insight. Can you tell me where you're looking at in the FSM? Specifically which book and what page would be great. I think I'm in the same page but just want to make sure.
If it's the expansion valve leak then that's an inexpensive replacement. However, knowing me, I'll just replace both parts since everything else was replaced as well.
Beav,
I lost brand new R12 in about two weeks

I'll look up at the drain hose. Thanks for the idea.
