Update !
I went on vacation for a few weeks without my car ) :
I went for a drive, very well deserved drive yesterday 8/30/14. I have missed driving the car, and I was very anxious to get behind the wheel again.
I drove about 10 miles and my informat center dash went frozen again. I parked for 10 min. Walked away.
Still not working. I headed home. I walked away for an hour or so. Still no AC, no radio control, no center dash control at all with vent air fan blasting away without any control.
Has anybody else running into this situation?
I guess dealer is my next stop. I took it in ounces before with no assistance (to Victory Chevrolet and Cadillac in Petaluma).
I'm going to try a different dealer.
Cheers !
