uprinting1

hello, I connected the gauges 2 weeks ago and it showed the same low pressure on both sides, 34psi, the lines had different temperature, one was hot and the other one cold, the clutch on the compressor worked fine, when I turned it on, it engaged and you could see it spinning, same as fan, today I did the same and the compressor not working, I mean the clutch not engaging, the lines, high is a little cold and low is nor cold or warm, fans not working, I interchanged the relays and checked the fuses and they seem to be good the pressure is 29 psi on both lines the temperature outside 90 degrees on both cases, what is the problem with it? where do I start?
thank you
