Dust in interior. 2014 GMC Sierra.
My new 2014 Sierra has a terrible dust leak somewhere. We were driving down our rural country road the other day and all of a sudden we were completely fogged in the cab by dust, could hardly breath. A friend has a 2014 Silverado same problem. He said it was coming in front of right hand rear door. I could not tell where this was coming from. It doesn't occur all the time, and also at varying degrees. Can anyone help me with this problem. Thanks
