When I turn on my floor heating, nothing comes out at the bottom, instead it comes out in the front (not windshield). I took out my cabin filter but still doesn't work. Any idea where next to troubleshoot?

Comes out the dashboard vents? Close them & see whether it comes out the floor NOW. The floor vents are pretty diffuse, so it doesn't have a very distinct stream.

If no good, then maybe a bad motor that controls the vent doors to open & close?
