i have a 2000 dodge knock against 1500. 2 days ago the air be ice cold and in a minute its warm. the clutch keep kicking on and off almost every 5 second. i put a pressure gauge on and in that is still freon in the system. but when the clutch engage the pressure drops down to about 20, afterwards when the clutch disenagages the pressure goes up to going on for 45. what could be wrong or how can i get the heavens to blow cold again?
Answers:
Feel the lines from the inside of the cab. The clutch might hold been kicking on and stale for the last year. That doesn't connote the system isn't working. If one of the lines is cold then it's the mixture door contained by the vent system that's bad.
You really have need of to monitor the high and low sides of the compressor at like peas in a pod time to see if it's working right.
