all of those lines that you pictured are pressure lines. The drain hole is located on the firewall. it may or may not have a rubber tube. it may just be an open nipple on the firewall. I looked at my car today and found it. The diagrahm i gave doesn't show those high pressure a/c lines in the way of the view but if you look directly at the firewall just below the a/c lines you will see the drain tube. hope this helps. A mechanic probably could clean it out for you cheaply though if you are having too much trouble finding it. Good luck my friend. If i can be of any further assistance let me know.
