So I searched for a while and no answers so here goes...

I have the standard cracked defrost vents and am replacing them. I touched one and it fell apart and I quickly realized there are screws and mounting brackets on these things on either side... How do I get at them? does the front section of the dash just pop up? Very fragile area and dont feel like breaking anything else today.

 

triangle defroster vents just pop off

 

Referring to the tough to get ones up front.

 

Oh that one- Center is a small cover, pop that cover it exposes a screw

 

You won't find these at the dealership anymore..Mazdatrix might still carry them.

 

Removed middle screw. There is a small metal plate holding this section of the dash down. As I previously mentioned all of these dash parts are fastened from underneath by screws. Now what? Do I lift off this forward section of dash? Because its pretty snug and I don't want to break fragile stuff that's hard to reach. Are there more screws behind glove compartment maybe? And yes MazdaTrix still sells some of them

 

Found it in tech manual. Once you pop it up, you have to rotate 30degrees. Go figure.
