Heater/AC selector bezel.

On ALL of that particular type bezel, to the left and right of the control section, on the BACK of the bezel, are 2 STUDS.......they're held tight with NUTS......not speed nuts.....regular hex nuts..........The speed nuts go around the edges, unless someone has already removed them.........

After the radio is out, you can access the nuts from underneath if your hands and wrists aren't too big.........they're a pain........But they're there, and you have to deal with them. If your glove box is apart, it's easy from the right side........and if the dash cluster is out, the same from the left.......But if not, you gotta stand on your head and go through the bottom of the dash, with the radio removed.

I've done MANY of these dashes.........all the same.
