hi,maybe some one has an idea,95 aurora,turn signals work,running
lights,tail lights,but no upper brake or brake lights at all,,switched out
brake switch under the dash and changed the bulbs,i did notice right above
the brake switch,thier was another simular looking switch to the brake
switch,but was somewhat bigger and also had a black vaccum hose along with
the electrical connectors(maybe something to do with cruise)can't find a
blown fuse.does anyone have an idea if thier is something else other then
thinking a shorted wire(wouldn't a short have an effect on a fuse or
stopping the other function on the lights)?

Did the switch you changed have an orange and a white wire ??

According to wire diag, that should be the brake light switch. The
orange is constant 12 volts from battery and fuse. The white feeds 3 things
1. L&R brake lights via turn signal sw
2. 3rd brake lite direct
3. Cruise Control/Shift Lock (you don't say if cruise or shift works)

There is a splice of the white wires somewhere for these 3 feeds.
Perhaps it has come undone. You probably have an open somewhere, not a
short. A test light or voltmeter would be handy to have.
