    Hey.

    I am writing this post totally annoyed.
    Immediately after turning the ignition switch, half of the electrical system stops working (windscreen wipers, air supply and certainly the fan on the radiator (!)).
    When I start the engine, I have to turn on the ignition a lot to get everything back to normal.

    I am a complete layman, hence the question: What could be wrong here? It's definitely something with the ignition, I read something about the ignition cube, but is it really it? How to get to her? I can order and exchange, only I will need your help.

    In addition, the car starts up normally, while driving, there are no problems with it, no disco or something. As it will surprise, it works until the engine is turned off.

    Why do I want to do it myself? I live in a village, we have 2 sites here but they are still full, I have been waiting for my scrap metal for over a month before they did it and I don't have time for it, because I have to ride something to work.

    I upload a video to illustrate the situation:
    [Film: eefb0c0e07] https://filmy.elektroda.pl/74_1508576782.mp4 [/ film: eefb0c0e07]

    Please help :(

    You need to unscrew the steering column housing, with 3 screws from the bottom, and probably 2 in the front on the sides - if you turn the steering wheel 90 degrees you will see two screws hidden behind it.
    The ignition cube is sticking to the ignition on the screw? On the "other" side of the key, which is next to the key, you are not in the mood for a while

    Also check carefully whether the pin from the ignition, its metal casing, transfers the movement of the key in the cylinder - this can also be a problem.
    In addition to the ones mentioned above, the starter starter also cuts off the cigarette lighter socket :?: , ABS and power supply to the fan relay (s). Fuses in the cabin F18, 19, 20.
    Try to buy the original cube. Or try to clean, it is on the latches, and can be unfolded and reassembled :)

    Thank you so much for this answer!

    So yes ... I undressed, I took out this ankle and checked the movement of the pin inside - it looks ok, but I also see that "ours were here" :| Insulated cables at this cube ...

    If it cuts the cigarette lighter socket, I will check how I fold it, because I didn't pay attention to it before. I even checked the fuses with a meter, they are ok.

    I checked the transition between these soldered cables and the plug itself, it is ok.
    I wiped the contacts but did not change. Still nothing works. Yes nothing. After firing, you can not lower the windows, turn on the rear window heating, the cigarette lighter works.
    And the "check" is still lit after firing up: / It went off when I was able to turn this ignition off to make everything work :(

    So what, but this cube?

    The lighter is a pickup, radiator fans are more important as you have two and a climate.

    The orange wire from the cube goes to connector C206 (pin15) - the first widest from below at the fuses. Gives electricity from the cube?
    As a result, do you have power on the fuses?
    In the cube you have two copper sheets sliding over the protruding contact points connecting contacts from / to ... yes?
    One burned out, fused, soiled, does not touch the metal without supplying the abovementioned

    You could bridge this wire for a moment with pin 4 or 6, but you overload these still working contacts. ACC is a lighter and a radio, and I would choose it.
    You have two red ones, one is a starter.

    As long as the ignition switch is not in the ignition position, this is the power supply, because then everything works. Only after turning the key to ignition position does everything quiet down and remains so even after firing.

    These copper wheels are very dirty. I will try to clean them, but I do not know how to assemble it later.



    Okay, these puzzles didn't have many elements, I already know how it should be :D

    :)
    The easiest way was to check the current on the orange wire by turning / turning the cube itself with a screwdriver.
    From what I remember, you will not fold it badly, if it is bent to the ankle joints.

    I cleaned it and it did nothing: o Very interesting.
    Ok, I'll check this cable again.

    Added after 11 [minutes]:

    So yes: The key is slightly turned, just before the ignition position the fans work, the orange is 12V, if I turn the key it is still 0V and after firing it stays like that.

    Rivets hold plates to the connector?
    Whether the cube releases tension depends on whether it is good or not, the problem lies behind it.
    Turn it on manually with a screwdriver and check it light bulb control . Not a meter that can show voltage, but with a very low current through a faulty contact.
    Give plus 12V directly to orange.

    He looks out at her, but ...
    The cube does not have a return spring, this one is in the ignition switch housing, which means that the damage may be stuck in it - the pin does not return to the end, the "wheel" also, without reaching the contact. Here, "help" by holding the pin while turning the key. The bolt is a loose part, and it can also get stuck. I do not want this when the housing is screwed to the steering column ...

    As I wrote, the voltage releases, but stops when you turn the key to ignition.

    I do not know if the problem is not in this small copper circle in the ignition cube. It looks like someone once had a tin of something on it.

    The pin is rather ok - I turned the key and tried to stop it with my fingers, it was not possible :D

    I don't remember which circle I came following the starter, but tinning = thickening.
    You can also rub by filing the plastic protrusions on which the wheel is sliding like to better fit the wheel to the contacts. If I remember correctly, and you want to save the current ankle.
    It would be good to buy a new one, as with a screwdriver it also loses electricity. Do not skip the ignition cube's driving mechanism.

    I can try filing these insets. To be honest, I feel indifferent. If I don't make it difficult, I will order it today, it will come on Tuesday. I will go by bus to work 2 times, but the girl will not be happy that I won't come over the weekend :D

    I used to ride on the old one until today and she is fine :) However, a new one came and after the exchange there is a bit of lime: / Terrible trash or just has to make up. Earlier, the transition from ignition to start required little strength, now I have to bend the key properly towards the start so that the car starts firing: /

    If nothing changes, I'll send it to hell.

    Thank you for your help, I'm closing the topic :)

FAQ

TL;DR: Daewoo Lanos “no wipers/blower” after key-to-IGN is usually a worn ignition-switch cube: it drops power to 2 radiator fans and more. “You could bridge this wire” for diagnosis, but replacement is the fix. [Elektroda, g107r, post #16769829]

Why it matters: It restores safety-critical cooling fans and visibility functions fast for DIYers tackling intermittent IGN power loss.

Quick Facts

What’s the most likely cause when wipers, blower, and cooling fans die at key-to-IGN?

Worn or contaminated contacts inside the ignition switch “cube.” The orange feed drops from 12V to 0V at IGN, cutting power to C206 pin 15 and downstream loads, including both radiator fans. Replace or refurbish the cube to restore stable IGN power. [Elektroda, g107r, post #16769829]

How do I physically reach and remove the Lanos ignition switch cube?

Unscrew the steering column housing: three screws underneath and two hidden at the sides after turning the wheel 90°. Remove the shroud, then access the cube on the back of the lock cylinder. It’s latched and can be detached for inspection or replacement. [Elektroda, g107r, post #16769663]

What is the “ignition cube” on a Lanos?

It’s the electrical part of the ignition switch containing sliding copper contacts that route battery power to ACC, IGN, and START outputs. Wear or heat can pit these contacts, causing voltage drop and intermittent losses in key-on circuits. [Elektroda, g107r, post #16769663]

How should I test the orange wire feed correctly?

Load-test it. Turn the cube with a screwdriver and monitor the orange lead using a 12V bulb, not only a meter. Weak contacts can show 12V on a meter yet collapse under load. “Light bulb control” exposes that failure. [Elektroda, g107r, post #16769913]

Which fuses and systems usually go dead with this fault?

Cabin fuses F18–F20 lose supply when the cube’s IGN contact fails. You may see dead wipers, blower/air supply, ABS feed, and cooling fan relays. The lighter socket can also be affected depending on position. [Elektroda, g107r, post #16769663]

Can I temporarily restore power by bridging contacts?

For diagnosis only, you can bridge the orange IGN feed to pin 4 or 6 to backfeed the circuit. Choose ACC for lighter/radio if needed. Do not drive like this; it can overload remaining contacts. “You could bridge this wire…” is a test step. [Elektroda, g107r, post #16769829]

I cleaned the copper wheels and nothing changed—what next?

Check for burned or thickened spots on the copper wheel and poor rivets. Lightly dress plastic guides to increase contact pressure. If voltage still collapses under a bulb load, replace the cube with an OEM-quality unit. [Elektroda, g107r, post #16769958]

Is tinning the copper contact a safe repair?

Tinning adds thickness and may restore contact briefly, as one user reported success. It’s a temporary fix and not durable for high-cycle IGN loads. Replace the cube when possible to avoid recurrence. [Elektroda, młody14, post #16770004]

After installing a new cube, the key needs more force to reach START—is that normal?

Some replacements feel stiffer. One report noted needing extra key bend to crank after a swap. If it doesn’t bed in quickly, return it and source better quality. Excess force risks lock or pin wear. [Elektroda, młody14, post #16778954]

Quick 3‑step: how do I confirm the cube is bad without special tools?

  1. Remove the shroud, expose the cube, and note the orange wire lead.
  2. Turn the cube with a screwdriver while powering a 12V bulb from the orange lead.
  3. If the bulb dies at IGN while battery is fine, replace the cube. [Elektroda, g107r, post #16769877]

Does the ignition cube include the return spring?

No. The return spring sits in the ignition switch housing. A sticking housing pin can also prevent the cube’s wheel from reaching contact. Assist the pin during testing to isolate the fault. [Elektroda, g107r, post #16769913]

What does ACC versus IGN actually power on the Lanos?

ACC feeds comfort loads like the radio and lighter. IGN feeds engine, brake power, wipers, blower, ABS feed, and fan relays. A failing cube can leave ACC OK while IGN loads die. [Elektroda, g107r, post #16769958]
