Hi all,
I have an 02 LS V6. Last summer, my AC went warm. It started with intermittent hissing coming from the dash. When the hissing stopped, air was cold. Hissing present, air is warm. I took it to a repair shop, he "recharged" it, worked "ok" for about month with minimal hissing, and then went warm again and hissing was continuous. Tried to recharge, this time to check for leaks, but system was already full. Since it cooled down, I've neglected trying to troubleshoot, but we get those odd days of high 80s, and I hate having to sweat them out. I'm guessing my DCCV is shot, but would that also cause the hissing when the DATC is in anything but the "OFF" mode? Heat and everything else works fine. Any ideas?
Thanks
