This seems like a problem many folks (not just Vibe owners) have, and it started happening to my 2009 Vibe this past week. Moisture is trickling in from the lower part of the center console onto my driver's side floor mat when the A/C is on. I presume the drain is plugged or otherwise damaged? The car has 223,000 miles, so it's to be expected.
Any other '09 owners have this problem? What did you do to solve it? Not sure if I can get at the drains myself or should just look to take it in. Thankfully we're getting away from hot temps!
