Hi Folks,
Wonder if anyone has seen this before and can help?

Both my rear indicators have stopped working at the same time.  It happened a couple of weeks back the morning after we had a load of bad weather here.

Strange thing is, the lights themselves work - they flash on hazards and when the central locking triggers, but neither work when trying to indicate left or right.

I've had a look through the fuse boxes but can't see anything obvious,  I'm assuming there's a short somewhere, but I'm not sure where.

The car is fitted with a tow-bar and corresponding electronics, I've not taken that apart yet, but I have had issues in the past with this causing the rear fog lights not to work


Anyone seen anything similar?

Many thanks in advance

I would suspect 1) bad/shorted towbar connections in the socket, 2) bad towbar relay (in the jack area), 3) bad flasher relay - not sure where thats located.

Can you plug a trailer board (or something similar) into the trailer socket to see if it works then?

Also, assuming you have a Toyota towbar kit, check your towbar fuse in the main fusebox.  

I think if that has gone, it could knock out the towing relay which would stop your indicators at the back.

Sound suggestions from Karl, as towbar wiring is a general source of problems.
IIRC there is a fuse for tow bar wiring in that same area Karl has described, in the jack cubby where the tow bar wiring connection/relay is located. Mine has a foam sleeve around it to protect from knocks etc and is tucked amongst the wiring in there on the left.
You don't say what year/model you have, but if it is the one with rear lights indicators in the bumper, as opposed to side column where only the brake lights function, you may need to look there. These bumper lights have a seperate metal shroud on them that traps water thrown up from rear wheels, and they eventually rot out. You can gain access to the bulbs, (just),  but to actually get at the metal shrouds/plastic light units, the rear bumper has to come off.
Look at the previously mentioned options first (easier) as the rear bumper removal can open another can of worms,
Nuts and bolts seized then snap off, brackets rusted through to twist and snap when bolts are turned etc these are mainly in at the back/underside of the bumper under load area. The large plasic clips on the wrap around bumper sections come apart ok with some fiddling
Hopefully it won't come to that.

Great advice!  Good thinking about that fuse in the jack cubby.  Thats a smaller size fuse than the one in the front, so would probably blow first too!!

Cheers folks,
Thanks for all the suggestions, I'll have a poke around when I get a dry few hours here and let you know how I get on...

It's a 54 plate, so lights on the side and in the bumper, the indicators are low in the bumper, but as I say the lights work when on hazards and when the central locking fires, so I'm assuming there isn't a problem there as I wouldn't have expected both sides to go at the same time.

The more I think about it the more I'm thinking tow hitch, but is there a separate relay for hazards and flash then?  Wouldn't you expect it to effect the whole circuit rather than just both rears?  Just trying to understand

The correct answer was the 10amp fuse in the rear where the Jack is kept.  Took the trailer socket apart and cleaned it up first, guessing it was mud and bad weather than lead to a short... but I'll find out if it all happens again...

Many thanks for the help... just need to figure out that the issue is with the other one now...

Well done in sorting that mate, it's always nice to have a happy ending !
Even nicer to get feedback on cause and remedy that could help others, so many don't bother. Thanks ! 🤗

These things are all about give and take, sorry it took so long to get back to you on this, was waiting for a dry day when I didn't have a dozen other things that needed doing

Hi all, new to this. I have the same problem regarding rear traffic indicators. Does anyone have a picture of the location of the fuse in the jack cubby please? I  cannot see a fuse in there. My vehicle is an LC4D-4D KDJ 120K. Many thanks in advance.

[karl2000]

You may have to hunt around a bit, I seem to remember its an in-line fuse, ie in the middle of a piece of wire,  So just fumble through the wires a bit and you should find it.

I think its a red wire....
(someone can confirm!)

[Tractionman]

Correct Karl, 2 actually, 1 in and 1 out.
Yep, you may have to dig around the multitude of wires in there, mine is in line with and below the big red Victron relay behind that flap you take off, on the left.

Many thanks to all;  I finally found the fuse, it was in the "cubby" as described but mine was tucked in the upper left corner behind some of the steel panelling, just a loose fit but you need to feel for it. The fuse had indeed blown and with a new fuse I have rear indicators again. For info the fuse as I believe described, is a ten amp. Mine was a baynet / spade type but larger in size than the 10 amp fuses in the main fuse box. However one of the smaller dimension but correct amperage works fine. Appreciate all the help.
