i/p lights,tail lamps, cruise not working

hi I have a 1995 cutlass that is having all the same problems that I listed
in the subject heading. Does anyone have any ideas on what the problem could be. Any help would be appreciated.
Thanks

There is a switch that is activated when the brake pedal is pushed.
It has two plugs.
One for the brake lights
And one for the cruise control cut off.
There is also a separate vacuum cruise cut off that is brake pedal activated. A black robber hose is connected to that switch.

Check both of them for looseness.
They may not be screwed in all the way.
The push button should be 100% depressed when the pedal is up.
The switch should actually touch the pedal and you should not see the button at all unless the pedal is depressed.

To screw the electrical switch in, the connectors need to be unplugged.
Or the switch assembly will not rotate around more than once.
There may or may not be a white plastic lock nut on the backside.
If so, tightening the lock nut may do the trick unless the pedal is just setting lower due to age.

just wanted to let everyone know . 250.00 dollars later my car is fixed.
The fuse block under the hood had corroded on the undrside and
ate away ate the wiring. NEw fuse block and some rewiring and I
am back on the road again.
