Inside of a/c and defrost switch

Red arrow points to the night illumination lamp (dark blue); cyan arrow points to the light transmitting prism from on/off lamp (amber)

Arrows are pointing to the night illumination pins (+ and - )

Same pins with the back plate removed,black return springs are visible at mid level (one spring for each white actuator)

Bottom view; night illumination lamps are removed and entire board can be pulled out

Top view; the main contact board can be pulled out as soon as on/off status lamps are removed

Inverted defrost switch actuator (left) with corresponding contacts on contact board;when flat contact spring breaks off the actuator the switch will not work correctly

A/c switch actuation is shown; it has 3 flat contact springs. The push button face cover (saying A/C) needs to be pried off the actuator; the actuator then slides out from the back
