• First problem, the partern are not orthographique.

• After, I have just build a basic spline cage, but I advice to use a polygonal modelisation because i had too many poly on air vent.
• Then, with a surface tool (threresold 1), I converted the mesh in editable polygon in order to clean it, trying to have just quadripatch.
  
• Next step is just adjusting all vertexes to get the better mesh as possible (N.B:use a reference with a meshsmooth is very useful).
