Default 2011 altima ac not working

I have a 2011 altima with ststic pressure in both ac lines of about 90 psi. The compressor clutch doesnt engage so I dont know what the pressures are with the compressor running. Air comes out of the vents but its not cold. Any ideas of what to check next

If compressor clutch doesn't engage, its likely you have a leak and refrigerant is empty. You must have a A/C manifold gauge to do diagnostics. The specs are found in the A/C manual for your vehicle. Manuals are found in Knowledgebase section at the top menu bar.

Thank you. I did use an ac manifold and static pressure on both sides was 90 psi. My next move is to troubleshoot the electrical aspects of the system. Just have to get the tools as I am not home

The static test is not very accurate test. If system is undercharged and still has refrigerant it will show some pressure. Only if you have completely evacuate the system you will not show any pressure. If I were you I would get a UV flashlight. I got mine a 25 LED bulbs on amazon. Shine the light on a/c compressor, receiver dryer, condenser to find the leak. Refrigerant leak will show up as bright lime green. It could also be the compressor clutch.
