Nice to see all the usual suspects still here. My '99 Cav has stopped cooling well. This is the same one I put the shaft seal in in Aug '08. I do not see any real leaky wet spots anywhere in the system. The compressor body looks dry, the front looks good as well, I can not see any real physical evidence of leakage on any of the outside components. The system sits at 90psi when turned off, so I am thinking it is still holding gas. But the vent temps are only a few degrees below ambient. The small line from the core is very cold to the touch but I do not get the sense that I am transferring much heat to it. The high side is about 70 psi lower than when I did the seal. (see this link)
I am wondering if maybe the blend door might be held open by something, or have I had and accidental discharge of gas ??
Thanks again for a really great forum you guys have created here.
If the line leaving the evaporator (the large one) is warm, it's not going to get cold inside. All signs point to being undercharged. Check for leaks, then evacuate and weigh in a full charge.

Yep, the fat line is warm. I'll poke around some more to look for a visible leak.
For now, I am relieved that I don't have to pull dash apart for blend door.
