Head light switch bezel removal and heater valve

Hi can anyone tell me how to remove the bezel on the headlight switch from the drop down panel? This is on an ‘S’ but would be the same for the MK11/420.
Second, is the heater valve default open or closed with no vacuum?
Cheers

The bezel clamps the legend plate to the drop down panel. Remove the knob from the front, and (I think) the switch from the rear, then you can get to the thin nut at the back. It has a wavy washer underneath it if I’m not mistaken.

Thanks Andrew, bother its busy in there :frowning:

At least it folds down - try an XK for some fun!
