97 blazer brake light problems

Alright been having problems for a while, got some of them figured out. Now to the newest, Had no emergency flashers, no brake lights at all, blazer wouldn't shift out of park, so 5 shifters and 2 steering colume's later, got my blazer to shift, got emergency flashers to flash, brake lights to work but they stay on all the time, figured it might be the brake light switch, so I went out pulled the switch off the push rod with it still plugged in brake lights stiil on, so I unplugged the switch and they are still on. Can anyone please help with this newest? :confused: :banghead: :screwy:

Unplug the turn signal switch, are they still on?

How many and what wires have power on the connector for the switch.
