Hi Claudio — welcome !
The light switch I believe has a brass looking “ lock” button on the metal box side of switch , you depress it and shaft pulls out . Clean the ceramic resistor and the wiper on it for good dash dimmer action . Check not open .
The wiper has a long story . On 60 the black plastic wash button operates a vacuum switch on back , added to electric switch . The shaft through switch for that is soft plastic and fragile , and a lock metal piece in the knob cuts into it over time . Attempts to pull off knob or button , knob pulls button too and almost always the plastic button shaft severs . Button falls to floor , then switch can come out . ( usual) . Once found a button under the F seat
To fix that I made a kit , see Bob’s 300 site one stop shopping . Fiberglass rod shaft., Also in that listing is a kit to put a strong v3 micro switch , simulating 61 washer switch , so same button can operate an electric washer pump ( like 61) . The one year 1960 trico synced vacuum washer pump is a bear , although used on corvettes and you can find rebuild parts and data there .
Hope this helps ...
