2008 Silverado 1500, V6, 2WD, 27xxx miles
My a/c comes on with a thunk and something in the front end sputters and shakes, reminiscent of a bad plug. It is very irregular, sometimes subtle, sometimes a little more aggressive, and seems to have no kind of pattern. Everything seems fine when the engine runs with or without the fan, so long as the a/c is not engaged. There seems to be no difference in this behavior using the lowest or highest a/c settings. The air coming out is cold as it should be. I saw another fellow on the FixYa site having the same problem, but no solutions have yet been posted. Is this a popular problem? Can I fix this in my driveway? Is it likely covered by my warranty (which expires in April)?
