When I start my car I can hear a fan in the pax side dashboard start to slowly turn, making a fluttering sound. This sound changes in speed and intensity based on the speed which I set the blower. Any ideas how I can inspect this part? What it could be?
If it was crimped it was put in wrong. Small side goes in. Try a narrow noozle vacuum while you are putting in a new filter. Use a good light and mirror to inspect.
