2005 nissan altima 3.5 compressor has voltage clutch will not engage

I just fix my 2010 Altima
The ac compressor did not engage
the fans were both running all time when ac on The problem was the high pressure valve located on the driver's side on the condenser
This valve controls both fans and compressor clutch

If the clutch has voltage and does not stay engaged, the magnet in the clutch is failing.

pressure plate could be bad they make new broke stuff every day

possible the clutch master cylinder or the mesh sincronizer. that has always been my experiencewhen that happens

If the refrigerant is low a safety switch prevents the compressor clutch from engaging.

no it could be air condition clutch that engage/disengage the air condition compressor and disengage it through the pulley or could be the pulley bearings one of them . also check the solenoid that controls that clutch .
have a good luck sir .

test relay and the IAC valve

it could be a conscience that the wipers stopped too, because elctricly these are not sharing any resources.
there may be a leak in the system. when the freon gets low there is a pressure switch that disables the clutch to prevent damage.

the problem is at the system that runs the ac compressor: it can be the belt that is slipping or the system that couples the compressor(it's like a clutch, but with an electromagnet on it) which maybe doesn't engage well the compressor

Check A/C compressor relay. When you say it seems to be full of gas(freon) have you actually put a pressure gauge on the system? If the pressure is too low, the compressor will not engage. If the compressor relay is functioning, check for power at the compressor clutch. If it has power to it and it still is not engaging, the A/C clutch may need replacing. It is usually almost as economical to replace the complete compressor with clutch installed than to just purchase a clutch. Keep in mind if you replace the compressor you should also replace the receiver/dryer also referred to as the accumulator.
