I posted this back to my original post, but expect most did not see it there, so am reposting for those that are interested. For those not familiar with the original post, my A/C would blow cold at first, but would quit working after 10-15 minutes.

After getting a dealer repair estimate of nearly $1500 due to bad compressor (and a few other items), my options were to live without A/C, take out a loan, or get another estimate. I decided to take it to Swedish Engineering in Marietta. The bad news is the original diagnosis was correct, the compressor was bad. The sort of good news is the repair bill was $870, or roughly a $600 savings over the dealer estimate. This was for a compressor, receiver/dryer, orifice tube and recharge.

The rest of the bad news is that I suspect that some of you who are experiencing similar problems which haven't responded to any of the suggested fixes, especially if you have an older or high mileage car, might have the same problem. I had been hoping for an easy and relatively inexpensive fix. Now I am just hoping that the fix will last a good long time.
