Black and white hoses under front bumper cover
 

While removing the AC system I took the front bumper cover off today. Front AC line and both evaporators have been removed. History of the car is starting to show as it obviously has taken a little (I expect) hit on the front left. Many items not properly fastened or connected. So overall a good time to make it all well again.

So on to the question. There are two rather thin hoses that seem like vent or drain hoses. A white one coming from the left front and a black one coming from the right. They come together in the center on a little plastic part that opens to the air. What are these used for?

They are not properly secured now and if I have an idea where they come from I can probably fix them in all places, cleaning up the front of the car.

Removed the wheel liners today and found out that these hoses are vent lines for the headlights. That also helped to secure the center vent piece. Just have a broken clip to replace for securing one of these hoses.

One more rattle solved I guess ;-)
