Default Blinkers come on but dont blink, new relay, and hazards don't work.

Hey gang. My 99 Camaro Z28 blinkers weren't working when I bought it back. They come on but dont blink. The rear tail light harness was all chopped up with butt connectors and all kinds of trash. I replaced that with a new harness and replaced all of the halogen bulbs with LEDs including dual filament bulbs for the brakes. The front blinker sockets were both burnt up and cracked. I wired in new ones and replaced the bulbs with switchback LEDs. And I've replaced the blinker relay with an EL12 relay. All of the bulbs work properly, the switchbacks are white when the lights are on and change to amber when I turn on the blinker. The tail light blinker bulb stays off when the lights are just like factory, then comes on when I turn on the blinker. They just dont blink. The hazard lights dont work either but I'm assuming that relay is bad as well because I believe it's a separate relay. Is there another fuse or relay under the hood that might be bad? What do you guys think? Thanks.

I would guess it's because your turn signal flasher isn't a no-load LED flasher. The EL-12 is an electronic flasher but it still needs some load. It will work when you replace only the front lamps with LEDs but not when you replace all bulbs with LEDs. And of course the original thermal flasher for the hazards won't work without a load either. You need an LED no-load flasher like a FF552NLF. Or you can add load resistors at each lamp to produce the equivalent load for the flasher.

Well like I said it wasnt working before with the halogen bulbs and a factory flasher either. I replaced the flasher with the EL12 just because that's what I read in a sticky thread on here to do. But I dont think it's the issue. I'll try the no load and see but I doubt that will be the fix.

Also gang I dont have the covers for the fuse panels in the engine bay. But i pulled all of the see through fuses and none of them appeared to be blown.

Is the hazard relay the one that sits in the holder/clip just behind the HVAC controls down by the drivers right leg?

The turn signal flasher is clipped to a bracket just to the right of the opening when the knee panel under the steering column is removed. It's near the OBD2 port. The hazard flasher is on the other side of the steering column farther down near the floorboard.

Ah ok, well then I've replaced the hazard flasher with the EL12 and not the blinker flasher. I'll have to change that. But even so the hazards still don't work at all. The hazards don't even come on when activated.

That could be a whole other can of worms. I assume that your brake lights work? If not then the STOP/HAZARD fuse is probably blown. Otherwise, we can get into various diagnostic steps if you have a test light or multimeter.

Brake lights work. Fuse was blown, idiot PO put a 5 Amp fuse in a 20 Amp slot. Fixed that and they work just fine. After that I checked all of the other fuses and they all appear to be good.
