Flashers&Hazards not working

Hey all. I’ve went through all the old posts... I’ve tried the fuses first (nothing). I swapped the relay (nothing). I checked the hazards switch (nothing). I’ve put the volt meter on the fuse slot and getting power. Tested the relay slots with meter and it’s working.

I’m out of ideas... just finished a clutch swap and post this I have no flashers or hazards. Any recommendations?

I do want to add... when I press the flasher stick down or the hazards I do not see anything on my dash.

Judging by what you said you've checked, I'm a little stumped. I was looking at the wiring diagrams (I've attached a copy of the page below) and I notice that the power for both the hazard flashers and directional indicators runs through the hazard switch and then through the turn/hazard flasher relay. The directional indicator gets its power from the flasher relay and the signal for the hazard flashers runs back through the hazard switch before going to the lights.

I'd make sure to check power at the hazard switch, terminal 3 should have battery voltage when the ignition is turned on (power from fuse F6, 7.5 amp), and terminal 1 should have battery voltage at all times (power from fuse F9, 15 amp).

If you do have those correct voltages, I'd check power at the turn/hazard relay. At terminal 4 on the relay you should have battery voltage when the ignition key is turned on, and when the hazard switch is pressed but you should not have voltage at any other time.

The last thing I'd check is to see if you have a pulsing battery voltage signal at terminal 6 on the hazard switch when the hazard switch is depressed (I don't expect you'll have voltage at this terminal if the flashers aren't flashing but it needs to be checked for clues).

Good luck and let us know what you find.

Okay. Tested the relay port 4 and have power with the hazards on and hazards off... if I’m only supposed to have it one way or the other then I’m assuming the switch itself has failed

Do you have voltage at the turn/hazard relay terminal 4 with the ignition turned off and the hazard switch off? When the ignition key is off there should only be power at terminal 4 if the hazard switch is depressed (turned on).

I pressed my hazard button years back and my turn signals started to behave oddly. About a day later before I got around to investigating, everything went back to normal. I've been told that the switch the operates the hazards is very flaky in these cars.

Yeah I have a feeling that this button has failed. Although what seems strange to me is that if the button is functioning correctly then it should have power going through pin 2 to pin 4 on the relay... Which currently it does have this. So shouldn't my flashers work correctly right now? The failure is when I press down on the hazard and it still puts power through pin 2 onto pin 4 on the relay causing the hazards to never kick on.

I checked the little resistor in the hazard switch and it is performing the correct ohms.

I called my local lotus shop to see if they have a used one around to let me try plugging a switch in... I really don't want to ditch over $80 and it still be something else causing the problem!

There should be power at terminals 3 and 4 on the relay, terminal 2 is the ground wire. It is possible for the hazard switch to be the culprit, after the signal leaves the relay at terminal 3 it runs back through the hazard switch, giving it another chance at failure.

Thanks again for all your assistance Jet! I had the local shop pick one up from Lotus HQ... Thankfully which is only minutes away from where I work So the button will be here today.

Well... it wasn’t the hazard button... nor the relay. Stumped.

Have you checked to see if you have a good ground on pin 2 of the flasher relay??

It was as simple as autozone looking up and handing me the wrong relay... It was a 12v 60w+ three pin relay... but they gave me a EP34 not the EP35. I will say in their defense the box did say EP35 on it but it must have been returned with the wrong relay etc.

Once I went to Oreilly's and picked up an EP35 everything worked. Guh so frustrating but I guess I got to see a lot of parts that I've never seen before on the Exige lol... Pulled that entire dash apart looking for signs of a mouse or damage.

Thank you all for your assistance!
