2003 Merc. SABLE. AC works great for 1/2 hour on the highway. Then No cool air. We shut it off. An hour later and 70 miles down the road , it works again. Always cold air… no matter where you set temp. 4 times to 3 mechanics. No one can solve it. Please help. ---

By no cool air do you mean that you don’t feel any air coming out the vents or the air coming out the vents is not cool, but it is moving? ---

Keith. Almost no air coming thru vents. What we do feel is warm.
