Probably too much gas and the high pressure switch is stopping the ac compressor from working
SOURCE: 1999 Nissan Altima GXE, AC is intermittently
check pressure it may have leaked out already, also pressure test will tell if compressor is bad or other leaks, u can put dye in system and look for leaks yourself availible in most part stores, look at front of vehicle and look at condesor and see if any obvious damage
SOURCE: front a/c is cold rear is not freon is fully
This is caused by a bad expansion valve in the rear on the evaporator. This or a bad dampener motor in the rear. You have to take apart the right rear inside molding and trim to get to everything. Be careful taking things apart try not to be rough with anything. You can also check the lines on the bottom of the car under the rear passenger side. You will see 2 aluminum lines, a large one and a small one, the large one should be very cold and the small one should be very hot. If either is the same as the outside temperature then you have a problem in the expansion valve or evaporator. I recommend replacing both of them at the same time.
SOURCE: My blower works for air/heat but only blow luke
Look for a heater control valve under the hood connected to one of the heater hoses and make sure the valve is operating properly. This is what allows the hot water to pass through your heater core. Also your heater core may have a blockage.
SOURCE: arcondition blows hot air, freon in the blue and clutch on compressor engage
Make sure your blend door is closing all the way and that the actuator actually works.
