Re: I have a 92 lumina. The turn signals dont work.
The hazard lights has it's own flasher, change the flasher for the turn signals and see if that works. To find out which flasher it is, put on the hazard lights, and put your finger on the flashers, which ever one you don't feel clicking is the turn signal one.

I can almost 100% guaranty the turn signal switch is the problem. Power for the brake lights starts at the brake switch. power then splits from there and the third brake light gets power directly from the brake switch. Since the turn signal and the brake lights are on the same bulb power for the brake lights is routed through the turn signal switch. the switch depending on what position it is in will allow brake power or turn signal power to there respective left or right brake/turn bulbs.
If you hold your foot on the brake pedal and wiggle the turn signal and or play with the hazard switch the brake lights will almost always intermittently start to work. this will confirm a bad turn signal switch which is pretty common on GM vehicle with this style setup.
Well usually when the third brake light works and the others don't, the problem is in the turn signal switch. The center brake light is separate from the other two as far as circuits go. The thing that puzzles me is the cruise. It could be something else, because the only way a faulty brake light switch would kill the cruise control is if the switch was stuck on. I think I would check the circuits in and out of the turn signal switch.
I suspect there is a problem with the turn signal/ hazard switch. turn the turn signal on left or right, if it doesn't flash, grip the hazard button and gently wiggle it around, if the signals start flashing, replace the turn signal switch. The Brake lights are wired through the turn signal switch, if the 3rd brake light works, the brake switch is OK. I don't think it has anything to do with the anti theft system (at this time)
hi this sounds like the flasher box for the turn signals my be u/s they run on a separate box to the hazards, i think you will find this in your fuse box it should be one of the relays in there, also have you checked the fuse for it as well? hope this helps
for both issues, could possibly be the flasher unit for the blinkers.....which could be separate from the hazard flasher unit...(happened on my 92 chevy lumina) or the actual turn signal switch which is located in the steering column....not the stick you push, but the part inside that the lever controls (also happened on my lumina............3 times)
start by checking the flasher....its cheap maybe 3-4$ for a new unit.....if thats not it and you figure out its the switch, go to a junkyard.....its wayyyy cheaper
