Ok, the bosses (wife of course) air conditioner has gone sour, 2005 Grand Cherokee Trail Rated Hemi. It still blows cold but not the way it should. Checked the pressure and it's on the high side (red) Although it's a 2005, it's still cherry with only 110,000 miles and a good factory paint job so it's not going anywhere. Any possibly easy solutions?
Also an occasional rattle in the a/c vents, probably a bad valve?
