Does anyone have a bad smell comming from the A/C vents. I have a 2011 terrain and I notice a moldy smell from the A/C vents every time I start my terrain up. The smell only last about a few seconds then goes away. I took it to get serviced and they sprayed some kind of disinfectant and also turned the after blow on. It was good for about 2 days then the smell came back. Anyone else had this problem? and if it got fixed, what was done to fix it. Any info/help would be great.
