Hazards work but blinkers dont

Trying to diagnose my blinkers. The old relay was bad when I got this car and now I'm trying to get the blinkers to work. I swapped for an electronic flasher relay this morning and now the hazards are working, but not the individual blinkers. I checked continuity in the stalk and it seems to be functioning properly. Any ideas? Can't seem to find this same problem in searching.

Replace fuses, check bulbs, clean grounds and bulb housings. Mounting screws ground the fronts, rear ground is in trunk near on the rail between the spare tire and gas tank. Lots of info in the FAQ section. A fairly common issue. Try Site Search it works better than Forum Search.

I had the same issue. Found wires were installed backwards

on my front turn signal housings.

Also, Hazards are wired to work even with the ignition off (i.e. unswitched 12V), while the blinkers only work when ignition is on -- (different power source than the hazards) -- so check the fuses for the blinkers.

Thanks for the tips! The wiring could be backwards though in the front and cause this issue? Seems as though if they blink with the hazzards…they should blink with the blinker stalk. I'll give that a shot tomorrow as well as maybe work the grounds too. Just seems goofy that they do work, just not with the stalk.

Also the dash light never comes on for the blinkers, however not sure if there is a bulb in it or not currently.
