Ac not working no air blows out vents 1990 camaro v6?

well working on a/c and the blower motor is 2 different things... if its just not blowing cold air then could have leak needs fixed and then recharged with freon and possible pressure sensors replaced if they dont work. or A compressor if it wont work but the compressor wont work untill the sensors say it has proper charge in it so u cant automaticly rule compressor is bad. so u test the pressure of freon in lines make sure its full. then find low pressure sensor and unplug it and use paper clip to jump the sensor out to see if compressor will kick on. dont do this if u dont have any freon in ur lines. make sure ur settings are set on full blast and cool inside vehicle. okay if u just arent getting no air at all thru the vents then that means the heater dont work ethier.... so that means u need to find a fuse or the switch on ur dash isnt working. some how or another ur not getting power to the blower motor or check the ground
