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.
