Turn signal & hazards not working - trailer light on

Well my turn signals decides to stop working on me in the middle of a trip. I had used the hazards several times and now the trailer light is on. Any help would be appreciated. Checked the fuse, it seems fine

Bad hazard switch is what I would place my bet on.

Any way to get around it for the rest if my trip like removing the switch?

Not that I am aware of. You may try squirting electric contact cleaner into the switch. Worth the couple of bucks the can would cost.

I would start jiggling all of the connectors around your indicator lamps. Sounds like a bad ground to me.

I've had a similar situation on my truck lately (intermittent) and it seems to be related to the switch. If I wiggle it around a bit it will work fine. Feels like it has a lot of free play from worn contacts.

So I'd second the contact cleaner as a potential quick fix until you can further diagnose.

Okay, now I'm not so sure my issue is the switch. My intermittent lack of flashing is now happening more often than not and there is no flashing with the hazards either, so I'm thinking the flasher unit is bad.

Looks like I will need to do a bit of research on this.

Can anyone tell me where the flasher is located?

Sounds like a bad hazard switch. Just give it a gentle pull. And all should start working again.

Mine did the same thing. I had used the hazard, then blinkers stopped working. The hazard button was not fully off. Pushed the hazard button a couple of times and all was good.

Thanks for all the responses. After sitting for two days, I cranked the truck back on and miraculously the turn signals work again. As has been mentioned I think it was the hazard switch getting stuck. I'll have a new switch on order but I'm just glad I had turn signals for the long ride back.

Sorted mine, it was the hazard switch. I found some great instructions. Rom a thread here on how to diagnose. I took the switch apart (which was surprisingly easy to do), cleaned it and put it back together again. Now my signals are working fine but I do think I'm going to order a new switch just in case.

Certainly seems like a wonky way to go about wiring the circuit but as with most British electrics, not surprising.

Yeah, Hazard circuits are always a mess. We just had one in the shop, same thing, the signals only worked if you held the hazard switch.
