Hey everyone, new to the forum, my dad has a 96 blazer that has a brake light on all the time, he had a problem with the trailer harness and blew some fuses and a local mechanic replaced the brake switch by the brake pedal, not sure it what order all that happened, and the light is still on all the time, fluid level is great and brakes work great as well, and the brake/tail lights work as expected

Does someone have a wiring diagram for the brake light system? or a link to where I can find one?

Also, the power seat does not work, I tried to check for power at the switch there was none, is there another fuse box other than the one in the left front door opening?

And lastly, the 4wd does not work, the switch works ok, each button lights up correctly and the transfer case makes an engaging type noise- no power to front wheels though- where should I start?

Thanks for your time!
