If the blower is working,it indicates your car blower system is ok.If the freon system is contain the correct amount and still clutch is not turning when the A/C switch is in the on position check the supply for the compressure.If there is supply that means the problem with the A/C compressur clutch coil and apply the repair procediure or replace A/C cpmpressure.If there is no supply Check the fuses,wiring system and A/C system pressure switch.

You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

You need to make sure the freon is correct,by having ac gauges put on the system,if the compressor is running the gauges will tell if there is a problem with the ac system itself,now,it can be the temp door actuator motor that is in the dash,if it is not moving the temp door open,it will need to be replaced.

No sight glass on the Saturn system. to know if it's low you would have to install a gage set and connect to the suction and high side of AC to determine if it is low on refrigerant or not. If the suction side has 30 PSI and pressure side is 285 PSI would indicate slightly low. So if it was about right like I mentioned You could have a plugged receiver dryer. You need the tools to do this job because of the expense of the tools to test the system.
