So last week, my wife was driving the Vette and said the air on the Driver's side blew warm while the Pass side was cold. I was out of town, but thinking "oh crap, dual mode gone bad". So during my troubleshooting, I found that there was oil around the cap on the High Pressure line (thinner line over the passenger fender). I read about a few C5s that had a similar issue and replaced the valve, tested and recharged their system.

So I started praying...because the alternative was an expensive dash pull to fix an AC door or bad module. Well, I am happy to report that the leak was from the High Pressure valve (prone to failure in GM vehicles), replaced and recharged. Happily blowing cold for the oh so soon, hot Mississippi summer days.

I never found much online about this and wanted to share for those who may experience this in the C6. I would have posted a pic, but Photobucket is down.

Thanks for the tip

Yea, thanks for the post. I haven't seen or heard about that before, especially that it's common in GM vehicles.
