this system has a shut down mode when it detects freon gas is low. if the system is cooling the car just by being reset then you may have a faulty high or low pressure switch, but if it is reset and turned on and is not cooling the car correctly then that is why is keeps going into shut down mode. this was set up to avoid a/c compressor damage, this wont allow the compressor to run and over hat itself due to low or overcharge in the system. the first step would be to evacuate the system and apply a vacuum for 45min. then recharge the system added oil and dye, (dye is used to find leaks if system looses freon.) then run a/c and do a vent temp. test, making sure compressor pressures are good and vent temp is good, at this time shut down car and see if it goes into shut down mode. if it does then have the switches tested and check the compressor clutch, ohm it. start with this, if the system takes a few days to go into safe mode then i would say there is a leak and it is doing its job, now you will need the glasses and blue light to locate your leak.
try to throw cool water on the condencer front of the engine radiator and see whether any cool air comes in the car. If so see whether the pressure valve is working okey or not because might the pressure is not sufficient.
you have an adjustable throttle cable top & backside of motor.. very easy to adjust back down... my jetty stayed idled too low & would randomly rev until cleaned entire intake & adjusted pin on cable... check engine light went out and it auto cleared code almost immediately
best diagnostic method is dual head gauges. balanced pressure between low and high side in the off position is aroung 90 lbs. running low pressure is 20-40 lbs and high pressure 160-200, is the compressior not coming on? does it stay on, or click on and off. either might mean the freon level is low. try unplugging the low pressure switch on the low side supply line and shorting the pigtail wires together with a paper clip. does the compressor stay on now? if so and the air is warm or cool, freon is low. if the air is cold that switch is bad. if compressor still won't come on the list of possibilities grows longer: compressor, comp fan clutch, AC relay, restriction at several places... repair shop time...
You'll need to disconnect the high and low pressure lines from the compressor. Unplug the electrical connector for the compressor. Remove the belt. Unbolt the compressor from the motor. Reinstall, connect a vacuum pump to the high side A/C fitting, start the vacuum pump, run pump until to have about 15psi of vacuum and then disconnect the pump and refill with refrigeraint.
something not right here ,firstly why didnt you just renew the clutch instead of a complete compressor ?? secondly do you have a machine to recharge the system and if so are you using it correctly ,the reason i ask is because in the machine the low and high pressure pipes are interconnected in the body of the machine so yes it would show these pressures.When refilling a car once machine has weighed the gas leaving the bottle shut off the red line and start engine leaving the blue line connected ,run engine at 2000rpm with A/C on full for about 3 mins to draw the gas in from the machine .Then close blue line and and do a recovery to see how much gas was left in the machine.Also did you put compressor oil in when you re fitted the compressor about 100cc is enough ,this is better put in directly into compressor ,then vacumn to about -750mg or a stage one vac pump and omit the oil recovery cycle .When running the air temperature coming out should be about 7.5centigrade is good but some cars will drop to 5C anything below 9C is ok ,and forget to clean out pollen filter
