2004 Pontiac Grand Am

Car has been running a little hot, about 220-230, higher if stuck in traffic. Replaced tstat, sensor, radiator cap, fluids in December 2010. Started running hot again a couple of weeks ago, temp gets close to 240+, if traffic gets bad I have to pull over to stay out of red & now the A/C will be blowing perfect then start blowing hot air, back to cold, back to hot. Any suggestions??

You fan should be coming on with the A/C or when the temp hits about 225, is it?

Yes, both fans running. I tried taking to a shop close to home for diagnosis, pricing and they ran the car (not drove) for 30 minutes & it never overheated, ac working perfectly. The shop is across the street from home so It didn't run long enough, I guess to get hot. As soon as I put it in drive and accelerated, the ac immediately started blowing hot & temp climbing.

Then you probably should pressure test the cooling system. You're probably experiencing a coolant loss somewhere.

Thank you for your help. It is possible both problems are related? The place that told me they couldn't find anything also said if I had both of those issues going on that they would be separate issues??

They may or may not be related.
