Current symptoms: I do not have a right or left blinker when I use the turn signal. The outside turn signals and the dash indicator do not go on for either direction. When I put on the Hazard switch, only the left side of the car flashes. Yes, I do have a voltage meter. Yes, I did plug the Hazard switch back in before diagnosing. The left blinker no longer stays on when key is off because I turned Hazard switch off.

First of all, thank you for all the amazing and detailed information. Apologies for the slow response. I had a bunch of trips. So here is where I am at. Half idiot and half mystery. Idiot part-I put my phone on the Hazard light and defroster switches and turned them on. Hazards on wasn't my first instinct, because only one side was blinking. So I started diagnosing it as a blinker problem. After I disconnected the Hazard Unit to prevent it from draining the battery, the defroster still managed to kill the battery becasue I hadn't figured out it was me hitting the switches yet. So next step, solve dead battery problem. Mystery part- Both blinkers don't work (lights and dash indicators) now when actuated by the turn signal stalk. But the left one is the only one that works when the hazards are on (still does that . Fuse is good, bulbs are good. I checked the stalk before like I said and it seemed good. I can take it out again and do a pin out with an ohm meter next. Open to suggestions. Thanks, Adam

This is all great stuff. Thanks. I'll dig into it this weekend. The Hazard light circuit is a high contender since it is the only one to bypass the ignition power circuit. The second thing that points to this is that I took the turn/combination switch/stalk out, unplugged it, and it was still going.

1978 Z. Started the car, all of a sudden my left blinker went on. Couldn't control it from the stalk. Staid on when the car is shut off. Disconnected the stalk from the wiring harness. The blinker stayed on. I finally stopped it by pulling the blinker relay. Thoughts? My first thought is to replace the relay. Thanks
