Ms.Debra,
This problem is a time and material job, because of the area to be
covered doing job.
Many places to find, many places hidden, where it is hard to get to.
It will cost many dollars to get this job done, correctly anyway.
Slow leaks are very hard to find and much can be spent in finding the
right place to repair.
As you say Huge.
I would start at the easiest places for the orings to leak first.
The back of the compresser, and the condensor in the front of van.
Then start digging.
Good Evening

Subject: AC leak - how much to recharge
I haven't had a question in some time but I have one now. I've had my 90
Multivan since Jan. 2002 and shortly after purchase we had the AC
converted and charged. The mechanics put in a dye since it hadn't been
running cold and they suspected a leak. It blew cold all through the
spring, summer and fall of 2002. I might have used it once since then
and it was still blowing cold. However, today I tried it and even after
10 minutes, it was hot air. I'm not a big AC user but my husband loves
it. My question is: Are there more likely areas that leak slowly like
this and is it a huge, expensive job to hunt for it, and how much for
the 134 re-charge. Thanks.
