{"text":"Would anyone be able to tell me why on my 2006 freightshaker the A/C compressor kicks on for approximately 15 seconds and off for 10 seconds at a time all the time!  Not really knowledgeable on A/C units!  I do know the system is full on freon and there are no visible leaks!  Also the clutch fan in the truck is inop and is constantly spinning at truck RPM at all times! I was told that could be a issue with A/C unit, but again, not very knowledgeable with A/C!  Thank you in advance for advice!  Be safe everyone!","videos":"[]","link":"{}","pics":"[]","canComment":true,"externalShare":false}

","text":"One of the sensors is probably bad, can't really tell without checking. AC systems have a low pressure cut off sensor, and high pressure cut off sensor, and a temperature sensor on the evaporator  to make sure it doesn't ice.","replyToPid":385033}

","text":"he should get tacos and alcohol and think about it cuz that's what I'm doing. it solves every issue","replyToPid":385046}

{"replyTo":"","text":"it's cycling on and off. put gauges on it but most times it does that because you are low on refrigerant and you could have a leak or leaks and/ or the compressor is bad","replyToPid":0}

{"replyTo":"","text":"Could also be a bad clutch. Just a note, the clutch is supposed to spin constantly while the motor is running. It only locks and runs the compressor when the a/c is turned on. That’s why I’m thinking a bad clutch 🤷🏻‍♂️","replyToPid":0}
