I managed to easily remove the top half of my front grill, however, the bottom have seems to me molded (?) into the front fascia. Is this the case or are there fasteners somewhere? How do I remove it?

thanks.

 

The whole grill is attached by fasteners. The fact that you were able to remove the top part just means you broke the fasteners on the top. Well, actually, you may not have broken them but you slipped the grill tabs out of the open slots on the bumper. The bottom ones have the grill tabs going into holes (or closed slots) in the bumper. That's why you can't just pull them off. If you reach in and feel for them, you will detect the little flat metal clips that hold the tabs from coming out the holes. (If you push back on the upper part of the grill, you may see these clips.) If you don't care about breaking the tabs (like little plastic pins), reach in with a sharp, flat screw driver and pry the clips away from the bumper.
The proper way to remove the grill is to first take the bumper off, then remove the clips that hold the grill on.
