Oh those MF's...... to take them out you have to remove your instrument panel ie: bezel and gauges, then work your way from there to the back of the vent there is two tabs on top of the vent and two on the bottom, now this is the bit when you start swearing cause believe you me its tight as a nuns you know what behind there, you have to get something like 2 flat head screwdrivers long enough to be able to depress the two tabs at the same time (both top or both bottom) then from the front pull the corresponding side out. If your lucky enough i have found sometimes if you do the top tabs first the bottom tabs will just pop out. Good luck and make sure the kiddies arent around when ur doin it this mod is for 15+...
