[QUOTE="DSG2003Mach1, post: 13099961, member: 16477"] If you have the AC set on high and its still clicking on and off you are likely low on freon. The low pressure safety switch will make the clutch cut out if low side pressure falls below a certain number. There is a point that when the compressor is off low side pressure is high enough that it will allow the compressor to come on but when it kicks on pressure drops and it falls below the minimum pressure and cuts it back off again and the cycle repeats over and over. When the AC is off low and high side pressures will equalize so you might have 120psi on both sides and once the compressor kicks on you might see 50 psi on the low side and 190 on the highside (those numbers arent quite right but typically low side pressure should be under 60 as a max when the compressor is running and high side somewhere between 2-2.5 times ambient temperature) I wouldnt be surprised if youve sprung a leak somewhere so it may well happen again [/QUOTE]
