Turn signals just stopped showing up on dash and lights. Lever seems to work fine, just doesn’t display anything. Tried switching turn signal fuses, no luck. I’m pretty sure it needs a new flasher or something, but I wanted to see what you guys think. Before this, intermittently the signals would stop working but would work again once I activated hazards. Does not work anymore and isn’t responsive. Much appreciated.

It is common for the combination flasher to go out in these cars. Here is the location near the steering column so you can swap it out which would fix the problem. Check out the images (below). Please let us know if you need anything else to get the problem fixed.

Hey Ken L. I just tried replacing the combination flasher with a Novita EP28 led flasher. It did not work. Is this the wrong kind of flasher or is it something else?

I don't know about the flasher part number, so are you saying the lights are still not working on the dash or the blinkers don't work?

Blinker and hazards still don’t work after trying to replace flasher and fuses. Might have to get it diagnosed.

It sounds like you have the wrong or defective flasher. Here are the blinker wiring diagrams so you can see how the system works. I would check the grounds.

Thank you, Ken, I don’t know squat about electricity, but I’ll try finding the correct flasher.
