A/C clutch not engaging

My clutch on the A/C compressor would not engage and I was informed that the problem was that the compressor being dirty or clogged triggered the high pressure switch shutting down the clutch from engaging. If this was the problem, would the high pressure switch need to be reset to start working again, or would the clutch work when the pressure was within the parameters to allow it to work? and then shut off when the pressure was too high?

There is no reset or relearn for this type of situation, essentially you repair the problem and a/c works again. Most cars have a high and a low pressure switch and when things are operating with good pressures the computer gives the okay to continue running the a/c clutch. If u don't have access to manifold gauges to watch ur system pressures then u will just b playing a guessing game really. I suggest purchasing a cheap gauge set from harbor freight or Amazon, hook them up to the high and low side service ports and report back to us with your findings, so we can see the overall health and status of the system

I found and have listed an inexpensive manifold gauge set on the tools page of my website.
It is the same one I used in a few videos. This is a must have took for any and all AC systems troubleshooting

My question derives from the need to know if I have been dealt with unfairly by the dealership where I recently took my 2013 Nissan Murano, to repair my A/C. While my wife was running errands, the A/C was working fine and then no cold air. The fan blowing hot air was all. I noticed the clutch not engaging when I looked at it and no apparent leaks (which later was verified by the dealership) as I had no gauges to check the system. Looking on you tube, I found your video on a clutch not engaging on a 2005 Honda Odyssey. My situation was identical to the video in terms of the high idle being there when the a/c button was pushed, checking fuses, finding the relay and hearing it engage, (again no tools to do the tests to the relay that were done on the video). The video helped affirm to me that the problem was "outside" of the a/c system and aimed at being between the relay and the wiring down to the clutch and/or the connections at the clutch. When I heard that it was the compressor they said was at fault, I asked what they did to engage the clutch to figure out that it was a faulty compressor. After a lot of contradicting answers, that is where I got the answer that the high pressure switch being triggered would not let the clutch engage (due to the compressor being dirty or clogged)? So I am assuming that high pressure can be stored in the system to keep the HPS activated and therefore disabling the clutch for extended periods of time? Would this not have been apparent when the gauges were put on the system in the first place? I apologize for the unprofessional questions that gives you no definite parameters for you to work with.

Here is a chart to convert the Sensor Voltage to Pressure.

I want to give thanks to everyone that took the time to respond. I was trying to get all the info i could in affirming the problem not being the compressor. I was getting nothing but the run around with the dealership about how they deemed the compressor to be bad. They would not answer me how they got the clutch to engage the compressor, to where they could determine the compressor was bad, since the clutch was not engaging when i brought the car to them. When I picked up my car, I called for the manager to educate me on the compressor diagnosis, and that is when he blamed high pressure (due to a dirty compressor) shutting down the clutch. I did request the old compressor to be given to me (before they did the work ), which they did let me take it with me, and the clutch was still assembled to the compressor. I could of tested the clutch before asking for assistance in trouble shooting the problem, but I needed first to call them out (thanks to ya'll), on the BS reasons they were giving me as to why the compressor was bad. I got with the same manager today and he finally gave in realizing the high pressure that he told me was diagnosed, could not be diagnosed, without the clutch engaging the compressor. That's when I told him that the clutch tested bad. They are reimbursing me for the cost of the compressor and labor charged for putting it on I am glad to say. "Knowledge is a weapon"
