Dash noise on 2006 Kia Sorento
I have a 2006 Kia Sorento. I was leaving for vacation and just as I merged onto the highway, a noise appeared from the dashboard. At first I thought I had a hole in the windshield, however, then the noise came even when I opened the window. The sound was like a fan getting stuck on something but still turning. The car accelerated easily and no pressure lost. The faster I drove the faster the noise came. When the window was open, you could hear it from the door panel as well. The engine itself never lost power nor did any lights appear on the dashboard. It however was an annoying sound which lasted the entire trip of 10 hours. What could the noise be?
