It is probably not AC related. I doubt there is enough AC lubricant in the system to make what it sounds like you are describing. I suppose MAYBE they have more than I'd expect since they probably run another evaporator in the rear.
According to Mr. Helm, a total of about 10 ounces is all you should ever have in the system.
Make them give receipts for everything they do. How are you gonna prove you visited the dealer 4 times if you don't have the records.
See if your AC works, I know it might be hard at the ambient temperatures you are experiencing. If it works, there is NOT any AC lubricant leak. R-134 will leave the system way easier than lubricant.
What color is this fluid?
