This is the mechanical control unit of the heater blower/defroster,
had a bit of rust on it but that’s all gone now.
Desperately waiting for my new toys to arrive.
With a bit of Zinc salt and Zinc sheets, water and battery I will re-galvanize the cleaned surfaces.

The vacuum selector valve in pieces, out of the control unit.

Inside of the vacuum selector valve.

Left front windshield defroster vent, prepared to my standard before painting.

Inside needs a bit of cleaning too!
