If you are getting any cold air at all (less and less from your original quote), there's a possibility of air in the system causing the high readings. If you have a 12oz. can of refrigerant, load it in and see what happens. The most you'lll be out is about $10.00, plus, if you add it and the AC continues to degrade, you know you have a leak. you can buy the leak detection kits at most chain parts stores, all you need is an ultraviolet light (black bulb at Spencer's Gift stores does the trick) to check for the dye at all AC fittings.
Good luck

Mike,
I purchased a can of 134A and some leak dye. However the system isn't pulling the 134A from the can. Normally when putting it in the can gets cold which is a sure indicator to me it's going in. However it doesn't change temp and the can doesn't get any lighter. I tried it with the can right side up and upside down. Neither way worked. The AC was on and at full blast with the car running of course. Do I have a clog somewhere or is the clutch really not working even though it is spinning. I know the compressor is getting power. The pully spins and then when I turn the AC on the center (clutch section) kicks in. Maybe it's just not working internally and so nothing is circulating?
