Smile '92 YJ Brake Light Switch

The brake light switch suddenly failed (and verifiedd with my Fluke!!).

How on earth do you get your hands on the switch to remove it??? (Not to mention the accumulated under-dash rust on the locking nut and bracket)

Additionally, according to my factory manuals, there are four contacts within the switch, one pair normally open and the other closed. The N.O. pair are for the brake lights (again verified by fluke) but the N.C. pair puzzle me. The schematics within the manual only show the switch within a bubble and not connected to the main harness. Anybody got a clue what the N.C. pair are for?? All other lighting works quite well (No A/C nor cruise).

TIA...Ed in 'ol Virginny (and make the removal process simple 'cause this 62 y.o. 'taint as limber as I once was)

...NO brake lights!!!!!!

Though I can jumper the pins on the chassis side of the connect and get liights. Additionally, the Fluke shows no voltage leaving the switch to the light circuit...futhermore, with the switch disconnected, there is on continunity on the brake switch side.

The switch is toast......proven several ways !!
