Has anyone experienced their air condioning system hissing noise at idle. Is there anything that can be done to quiet this hissing down? I understand it is an intentional restriction in the system but the hissing effect is quit loud in the cockpit of my Lade. Maybe it is louder in some than others?undefined

Hi Brad -

Not much can be done to silent the hiss. My Escalade did it, my Father's does it, and both of my Suburban's and my 2500HD does it. Annoying, but normal.
