Default 2011 AC stopped working

I have a 2011 maxima and the ac stopped working. the 10a fuse is good and the pressure in the low pressure port is high. the clutch is not engaging, and I cannot find the relay. Somewhere I read that there is no relay now. Anyone got any suggestions on how to proceed? how is the connector to the clutch attached to the coil? how do you get the connector apart? I can fit two fingers on the side but unable to separate,

Easiest way to check the clutch is to run the auto active test. Get in the car with the driver's door open, turn the ignition on, push the driver's door switch 10 times, turn ignition off and then back on. The car should cycle through several functions. High and low beams, cooling fans, wipers, a/c clutch. Watch the clutch and listen for it to engage. You should be able to see and hear it. If it doesn't check the wires going to it for power and ground while the test is running. If you have power and ground and it doesn't engage then you have a bad clutch.

If the clutch is not engaged, the pressure on the low side will be showing static pressure, which should be around 70-80 PSI +/-. Operating low side pressure must be measured with the clutch engaged/compressor operating.

There's a tab on the top side of the female connector (the one in the back) that you press down and then pull the connector off. Since I have fat fingers, I sometimes employ a small, flat-blade screwdriver to assist.
