I got a 1996 Chevy Blazer LT, The turn signals, brake lights and hazards stopped working. What could it be?

if you have trailer wiring check it it might be a problem,, or you may have crossed something you have replaced, go through the switch and hazard, use test light / ohm meter

it is possible that you may have a blown fuse,check the fuses in the fuse box.....cheers

sounds like one of the circuit bords at taillights is bad

Does the turn signals or hazards work in the rear?? Yes... it may be the brake switch or the turn signal switch (power goes from battery, to the brake switch then to the turn signal switch, then to the lights. No? .. again.. possibly turn signal switch or the wiring between cab and bed.

Check your wires, the smoke could mean an electrical fire.

Locate signal flasher & swap with hazard & see if the opposite occurs, if it does, replace flasher.

Turn signal switch 95% of t he time. Try to work your hazards, if it stuck at all will also cause this.

Unplug the turnsignal switch. If it stops then replace the switch. This is a common problem. Alot of times it is the hazard button that melts and causes it because all the turn signal functions go though the hazard switch but you have to replace the whole switch to fix it. Let me know what you find or if I can help you further. Please rate.

did you check the fuses?

If so, then check the plug on the steering column....

When my blazer did this they had to replace part of the wiring harness in the steering wheel. It took forever for them to get the parts because we live in nowhereville, but once it was in it works again and no problems. I had to take it to the actual chevy dealer because none of the other places had a clue. good luck.
