Another hot day yesterday, even though we haven't had much of a summer. While at a red light I fired up the a/c & noticed the engine start to rev up & down almost to a beat. Then I noticed the display showed 'check air conditioning'. I quickly turned off the a/c and the engine stopped revving that way. Then while driving I tried turning the a/c back on again and the engine started revving the same way but this time the engine shut off after about 5-10 seconds. I restarted the car without any trouble, got home w/o any issues so long as I kept my hands off the a/c.
Friend seems to think i'm probably just out of the a/c fluid? Will bring it into the dealer Monday.
