What would you do?
1. ac blowing warm. Dealer said freon low. Couldn't find leak. Recharged freon. Blowing cold.
2. 8 months later. Ac blowing warm. Different dealer said couldn't find leak. Recharged freon. Blowing cold.
3. 3 months later. Ac blowing warm. First dealer (again) said freon low. Couldn't find leak again, recommend freon recharge.
Sum: there has to be a leak. 2 different dealers couldn't find it. Not sure what to do at this point. What would you do?

You would be AMAZED at what some dealer mechanics say they can do but ABSOLUTELY suck at doing it. Or have never done it. 
Add dye to the system and get a UV Black light and look for the leaked out dye.
If you see no dye, get a Freon detector with a LONG wand and put it inside the HVAC AIR BOX to see if you have a leak at the evaporator.
Its really that simple!!

Add freon yourself for $35 and get on with life..
Who cares if you have to do it couple times a year.
Way cheaper than replacing components that you can't quite identify as faulty

Mine has a slow leak too.
It lasts between 1 and 2 years. I have been adding freon (r134a) as needed.
The small cans are frequently only about $4 and mine takes less than one to top it off.
If my leak gets worse I will be in your same position and may worry more about finding the leak and fixing it.
Good luck.

I'd start with new Schrader valve stems. And good ones, not Chinese. And then bear in mind that the stems are considered 'secondary' seals by GM -- the caps are the primary seal. Straight from the service manual!
As the point of contact for the test equipment (gages or otherwise) leakage there can be hard to detect.

My 2000 had leak when bought from a dealer. Under warranty they put in new shrader valves. Again no ac after couple weeks. Problem was compressor. Its been 3 months and ac working fine. My hat goes off to this dealer that stood behind their warranty.

Go to your local parts house and pick up a can of freon with leak detect in it. The can that you add yourself with the gauge. Most come with leak detect but just confirm it has it. Next by a UV light kit. You can pick them up for $20.00. Top off freon and drive til ac goes warm. Pop hood and using the UV light kit you will find your leak. Ive had one of these kits for almost 10 years now and it makes short work on leak detection.
