65 Chrysler wiper and light dash knobs

[Boyd]

OK, how do I remove the wiper and light dash knobs? Radio knobs pull off. I have to clean them and I can't take my wife's tooth brush out to the old car. I am sure I will get caught! Please help.

Probably a 1/8" set screw on the wiper knob. The light switch is likely 'one' with the stem of the switch, you have to reach behind the dash and depress the locking 'tang' to release the stem.
Similar to this, p-poor arrow but the release button is at the end of it:

Can't see the set screw. Will try the release behind the dash. Thank you.
