Indicators

[newxmman]

Hi all, my right hand indicators are stuck on, all lamps work, no ticking. The hazard flashers are not working, no ticking. The left hand indicators are working and ticking. Any ideas what's going on and where I should look first.

Cheers.

ny ideas where I should look first.

Yes. The Haynes circuit diagrams in the Series 1 Circuit diagrams thread.

Diagram 7 covers the indicators.

Everything before the column stalk is the same, so the fault has to be after the that point.
There is a back feed of power into the right hand indicators from another circuit, a process of elimination should find it. Try removing each indicator bulb, or connector in turn. At some stage the rest of the lamps will go out, which means you have found the section feeding power in.

Don't forget to check all the Gnd connections are sound, without resistance. A 4.5A test lamp (55w headlamp bulb) is best for checking Gnd connections, as it loads the circuit.

As a matter of interest, what happens when you press the hazard switch, I suspect all the indicators will light up due to the crosstalk between the circuits.
What other lights are in use when the indicators come on, or are they on with all other lights switched off?

Your car certainly seems to have some strange wiring faults, perhaps it's time to properly inspect the wiring.

Is it a mk.1 or mk.2 .. mk.2 xm. Followed the xantia setup with alarm and texton boxes. When this happend on xantias its was one of the texton boxes.. I relay inside the box sticks..

That's a good call, very possible.
The alarm control should be behind the radio section of the centre console.

What is textron box? Where is it? Would the problem be the ticking relay under the passenger dashboard where a lot of relays are? Is that what you mean? Are you telling me also to check the feed to each indicator bulb? If so how do I interpret the results, what results am I looking for?

Thanks

The Textron box is the alarm control unit, fitted behind the radio section of the centre console. You should be able to access it via the left side, carpeted panel.
If the car has the original alarm there will be a button and LED in the console, below the radio flap.
The alarm has a feed to each indicator circuit, after the column stalk, to make the indicators flash.
In the alarm there is a relay for each indicator circuit. One of them may be stuck on.

A, normally rapidly, ticking relay at the left side of the dash is normally due to the indicator column stalk having copper shards in the grease, causing power to flow when the switch is in the neutral position.
Strip, clean and grease the switch contacts.

You have something feeding power into the right indicator circuit, so need to work your way from the column stalk to the indicator bulbs to see where the power is being fed into the circuit.
Use the circuit diagram and find an easy access connector to part, then use a test lamp to see if there is power at one side of that connector.
With the column stalk at the neutral position there should be no power to any indicator circuit.
The connector to the column stalk would be an obvious place to start.
Connect the test lamp and ensure it replicates the indicators, then disconnect the connector and see if the indicators go out.
If so the erroneous power feed is upstream of the test lamp connection.

Connect the test lamp between the feed wire and Gnd.
As a quick check, pull the hazard lights switch out of the dash and disconnect it to see if it cuts the power.
Both indicator feeds pass through the hazard switch so can be monitored from there.
Your fault could be the hazard switch feeding power to the right indicator permanently.
Unfortunately the power for the indicator flasher relay passes through the hazard switch, so if the switch is faulty, will need a connection making for the indicators to work.
Again, a strip and clean of the hazard switch would normally effect a fix.

Do you have a test lamp, or Dmm?
A low wattage bulb(1w-5w) and bits of wire will suffice.

I've had a look at the wiring diagrams linked to previously.
Indicators are Diagram 7.

Questions to answer.
Are the R/h indicators lit with Ign off, or only Ign on? Y/N?

Does the car have an alarm fitted, if so, Citroen supplied, or aftermarket?

Do you have a test lamp? Not necessary as you can see the indicators/dash lamp, but makes checking easier.

The Ign power feds via F5 to the hazard switch (G-B2), through the switch and out (G-B5), into the flasher relay (V-B1).
We know the relay can function as the left signal works properly, so the Gnd must be good ok.
The flashing signal then passes out of the relay (V-B2 to hazards, V-B3 to indicators). Again we know this is ok as the left indicator works.

Pulsing power (flashing) is sent to column stalk (N-A5) and hazard switch (G-A4).
The column stalk switches the power to either, N/c, left (N-A4), right (N-A2). We know the left side works and continuity to all is good. The problem has to be something sending power into the R/h indicator circuit after the column stalk.

When operated, the hazard switch sends pulsing power to the right (G-A2) and left (G-A5) indicator circuits.
The hazard switch makes is a useful place to test from as it is easy to access the connector and is interconnected to the indicators.

1: With the indicators on pull out the hazard switch and disconnect it. The lights should go out and cease to function in any mode.
Have the indicators gone out? Y/N
If Y, connect between hazard switch G-B2 and G-B5 to send power to the relay.
Are indicators lit? Y/N.
If N try the indicators, which should work properly, Y/n?
If the indicators are now lit the issue is probably the column stalk...disconnect it and see if the lights go out.

If the lights stay illuminated with the hazard lights switch removed and the column stalk removed, there is power being fed into the circuit from elsewhere, probably the alarm.
Locate alarm and disconnect it, then check for lights still lit, or not.

We can only help you if you perform checks are report back findings.

In absence of an Rp number, see attached OEM, Xm S1 indicators wiring diagram for Xm with the lights switch on the left column stalk. Advise if your car has the rotary lights switch as the connections might be different.
This might be easier to follow.

Ok thanks. I ll get to it. Meanwhile. I now realise the problem is intermittent. The right Indicators work today, lights flashing and relay ticking. Does this give you a better clue to where the likely problem is?

Cheers

[Dieselman]

No. It just says the issue is intermittent.
A sticking relay, or switch contact could cause an intermittent issue, but so could a chafed wire in the loom.

Work on it when it is faulty, read the diagrams, disconnect the items listed and you will find it.

Inspect the wiring and connections for the right turn signal and hazard lights. Check for any loose connections, damaged wires, or corroded terminals. Also, ensure that the bulbs on the right side are in good condition. Sometimes a faulty bulb can disrupt the circuit. The turn signal switch is often part of a larger assembly known as the multi-function switch. If there are issues with the turn signals, it might be worth checking this switch. However, replacing the multi-function switch can be more complex and might require professional assistance.
