The only issue that popped it's head up on the way home was that the dash AC would come in and out. It would be blowing ice cold for a few minutes and then everything just stopped. Few seconds later, it would do it again.
Any ideas?
X2, With a vacuum leak the climate controls will revert to default mode (defrost). This has the cold A/C air blowing on the hot windshield.
