Is it possible to remove the vents in the console? On other vehicles i have owned the vents were removable by sliding a screw dirver and removing fasteners top and bottom and then the whole vent unit slides out intact. I do not see any visable fasteners when i look into the vent, so are the fastened from the rear? which would require removing the whole dash? the vent that is to the the left of the instrument gauges on the drivers side is broken it will not open or close. so i wanna replace it.
