Weak cooling from the rear vents, a musty smell or oily residue near the rear A/C connections can mean a leaking or clogged evaporator core. A leaking fitting looks much the same, so with the engine off, look over the visible rear A/C connections for oily residue first, and leave any pressure testing to a shop.
