I took out the broken defroster vents on my FD and glued them back together. Since then i've tried a few things to try and get them to stay put including using double-sided tape around the edges and weather-stripping. i've noticed too that most of the clips are broken off of them. I'm also having a similar problem with my passenger side window switch which has popped out and I believe the clip on it has broken as well. I'm sure someone has found a way to keep these things in place, aside from buying new ones. Any advice is appreciated.

 

Just buy new ones, they are not expensive. Give Malloy Mazda a call.
