Firstly, let me know if this is the wrong sub forum to post in.

Ok I have a 58 Reg Ford C Max 1.6 petrol, recently I've noticed that my RHS indicator has stopped working at various times, what I mean by this is that the dashboard indicator does not flash, there is no relay click and no lights on outside (front/side or rear on the right hand side).

When this happens the LHS indicator works aswell as the hazards work (RHS front, side and rear all work).

The issue is intermittent and it "fixes" it self after a while seemingly when trying to indicate Right on and off a few times, clicking hazards, it will come back on and stay working. When working/or fixed it self, it flashes and clicks at the same rate as the other side and all seems normal.

As this is one of those horrible intermittent issues (until it gets alot worse). Does anyone have any suggestions on what it might be ?

A relay, but if so it would affect the both sides surely, there isn't a separate relay for right and left, is there ? earthing ? but if so how does it fix it self.

All ideas gratefully received.

Could be the stalk, if you can get to the contacts bit try squirting some switch cleaner in.

If this works treat it as temporary fix and replace the switch.

Hazard switch. lack of use maybe? cycle the switch a few times next time it happens and see if it clears, used to be a big problem with corsa's

a quick ebay search shows the stalk is not expensive, what I cannot work out is how to remove it. I've got the upper surround off and can see the stalk but there is no obvious way, i will try and remove the bottom surround and see if that gives clues. I don't want to remove the steering wheel if I have too.

There is no youtube video for this model, only earlier focus/cmax's which have a simple clip to release, but not in this mk2 C Max.

There is no one thing that bring it back to life, not the hazard, seemingly more just keep trying the indicator over and over again.

It does sound like an intermittent switch. Switch cleaner bought one of mine back to life, temporally.

I would try the cleaner but it seem to be a completely sealed unit with no holes.

Thanks for the suggestion though

As the fault is only 1 side & only when indicating that way it is 100% NOT the hazard switch.

As it sometimes works & sometimes doesn't & when it doesn't a few switch operations gets it going again it is 100% the switch or wiring for that side only.

Try removing & replacing the plug & make sure it is on well, after that it is a new switch, which would be my bet as has been said above.

Agreed my logic also follows this.

Thanks

You do need to get hold of a wiring diagram of some description, there is no guarantee that the column switch connects directly to the indicator lights, there could be a control module in between the switch and the indicator lights
If you can get to the column switch plug you can test for what voltage you get at what wires when indicating right, now when the fault is on the vehicle you can test to see if you are no longer getting a certain voltage out of the switch and this will prove if the switch is at fault or there is something else wrong

bks. On some cars the loom for the indicators goes through the hazard switch on the way to the bulbs, it was a well known and common problem on Corsa's back in the day as well as some Renaults, so it well could be a problem on that side although I have not seen a Ford suffer from it, another Vauxhall problem worth thinking about is the flasher relay dropping one channel.
