An a/c system with insufficient cool air may have one, or more of, these problems;
* low refrigerant charge; check system for leaks
* slipping compressor clutch
* loose drive belt
* clogged condensor
* clogged evaporator
* defective evaporator control valve
* faulty expansion valve
* faulty fixed orifice tube
* clogged receiver-drier screen
* clogged accumulator-drier filter
* moisture or air in system
* refrigerant overcharge
* blend door out of adjustment
May also check the a/c relay and the a/c compressor clutch engagement; wiring, any in-line fuse - to make sure the compressor is working.
