Thanks again Xzo6,
Yes the expedition does have the rear air, so it is a bigger system. Location to add refrigerant is a pain to get to. There are stickers on all my cars as to correct amount of refrigerant. How the heck can you tell??? My tech showed me how to read high side for just a little top off. If I have much more trouble I take it to the experts. I wish they still put in sight glasses so you could get a better idea what is in the system
I do remember one time a few years ago my 95 GT needed a little boost, but I could not get it to take any refrig. It was during the hot summer when you usually are going to have an issue if at all. I called my Tech and he said to spray cool water on the condenser coil every few minutes to bring high side pressure down enough to get it to take a little. Well it Worked !!!!!! I got the system over charged and it would not do any thing but blow hot air. In Fact the compressor would only run for a short time and you could hear the clutch kick out and It would not reingauge. At that point I realized what I had done and corrected the charge amount. Within 30 minutes I was crusing down the expressway with the thermometer reading a duct temp of 38 to 40 deg. Live and learn.
Every system (even the same one on different cars) is different and it takes some time to learn its likes and dislikes. I liked the old r12 systems, easier to work with and in general got colder.
Anyway - Enjoyed talking with you.
