Default 2006 LR3 SE - A/C Low Line has very high pressure

My A/C stopped working blowing cold. Everything "seems" to work.

I was going to add freon but I noticed that the pressure is very high, like almost 100 PSI high.

I made sure to run the engine, wait until it was at normal running temperature. Then I plugged in the gauge in the low line and it read ~95 PSI. External temperature was at about 75 F. I tried with "auto" mode in the ATC, with and without ECON. I tried in Manual at full blast too.

Any suggestions on how I can troubleshoot this further before I decide to replace the Compressor?

Thanks!

I would really appreciate some input here. Luckily I don't need the A/C right now but I want to take care of this before our South Florida summer starts in 3 weeks ;-)

Is the compressor cycling, not kicking in or running constantly?
