New A/C turns off and on. What could cause that?


Asked by Jul 13, 2017 at 10:25 PM about the 2009 Toyota Camry SE V6

Question type: Maintenance & Repair

A/C recently stopped working. Switched A/C even found out has an electric compressor. About a week later started blowing out hot air. Not all of the time but at sudden intervals. Took it back to mechanic and he switched out he A/C sensor. Good for about 2 days and now it just turns off an on  by it self. What could it be? Just spent 800.00 trying to fix it...cant afford much more....

Is the AC indicator light flashing when the AC is on?


It's on, but not flashing.


When this AC system was last serviced...did they add any dye to the refrigerant to check for leaks. Your description seems to indicate you might have a small leak in the system. Seems to me...if you spend 800 on an AC repair...that repair should last at least a year.


Mechanic already checked for leaks. None were found.


The diagnosis of an AC System begins and concludes with the use of an AC pressure test gauge set. Without the use of this equipment......well......a successful repair is unlikely. Suggest you find another Mechanic who knows how to use this tester.....for a second opinion.


Isis.....did you ever resolve the issue with this vehicle?
