Fiat Panda 2 VAN 1.1 2004. - The windshield wipers do not work

Best answers

Jak znaleźć przyczynę braku działania wycieraczek w Fiat Panda 2 VAN 1.1 z 2004 roku, skoro bezpiecznik, silnik i przełącznik przy kierownicy są sprawne?

Najbardziej prawdopodobną przyczyną są uszkodzone lub brakujące dwa przekaźniki wycieraczek w module BSI; po ich wymianie wycieraczki zaczęły działać [#17542699] Przekaźniki znajdują się w BSI, czyli za skrzynką bezpieczników po lewej stronie przy drzwiach, a nie w samej dźwigni kierunkowskazów [#18021830] Wcześniej warto sprawdzić napięcia i masy na instalacji, bo jeśli są w porządku, to winny jest właśnie BSI [#17461007] Sprawdzono też bezpiecznik F43 w kabinie pod kierownicą i był dobry, więc sam bezpiecznik nie był przyczyną [#17460865]

    The windshield wipers do not work in my Panda, they do not react at all to changes in the position of the wiper gear switch on the steering wheel.

    I bought the entire steering console on the scrap car, but after replacing it, they still do not work so the problem lies elsewhere.

    The fuse and the wiper motor are OK, for now I save myself by connecting them sharply - I installed a regular ON / OFF switch in the cabin, taking the + pole from the battery and through this switch to the engine, they work sharply.

    Can anyone direct how to look for further solutions to this problem?

    There is probably a relay out there that could be responsible for the inactivity.

    I checked the fuse F43 in the M001 box in the cabin under the steering wheel - it's OK.
    There are also relays in the B001 box in the engine compartment, but I have no description for it.

    You have a buddy BSI cabin module diagram, i.e. according to your description of the M001 box.
    Check if you have currents and masses everywhere. If everything will be ok, it will rather be BSi.

    It turned out that 2 relays from the wipers in the BSI switchboard were lost, I replaced them with new ones - cost PLN 20 and the wipers are roaring :)
    I'm curious what was the cause of the melt - can you see in the photos?
    I have already bought such a car, the previous owner probably had to reconsider something

    The relays are located in the BSI module, it is located just behind the fuse box on the left side of the door, where there is a lever for opening the front hatch.

    The good gives up, after unscrewing the fuse housing, I can see what is in the photo. The question is where are the relays? Do I have to undress anything else? Can I drive without the relays after removing the relays until I buy them?
    Or maybe someone knows their name and type in order to buy them in advance? Fiat Panda 2 VAN 1.1 2004. - The windshield wipers do not work

    Probably in this "box" with a purple plug, but if you can't find this "box" then what to do is replace the relays. Give it to someone who will handle it professionally and not sculpt.

    Thanks for the answer, but I was more concerned with how to get to these relays step by step.

    Added after 3 [hours] 14 [minutes]:

    Do I have to remove the entire bsi module from the car to reach the relays?

    Hello, I will join the question, I have a similar problem, only that it manifests itself in the second fastest gear, namely the wipers move 1 cm every 40-50 seconds and so until they reach the top, they return normally on the return. The given symptom occurs only in the 2nd gear position, while the intermittent, momentary and first gear work flawlessly.

    My question is whether the problem is with the relays in the bsi or in the combined steering wheel switch?

    best regards

    hello I am tricked into the question
    I have a problem with panda 1.2 2003
    new battery, new alternator, as soon as the engine is about, how do I connect the meter for voltage to the positive clamp but not on the battery and the minus - on the car body, I have 14.15 v, i.e. the alternator charges, but if it is negative - under the minus cable - the mass shows 12.5 to 13 v, i.e. it does not charge the same as the terminals connected to the battery, which may be the reason that it does not charge the battery, I have to charge the battery all the time every 3.4 days because it is discharging, i.e. somewhere there is a current or a short circuit somewhere I plugged in the ammeter, it takes 0.05 mA at a standstill, a few times in the winter the power steering indicator turned red and there was no support but after restarting it reset, I checked the fuses and, as in the post, when I pulled out the 70A fuse, there was no current consumption 0 , 00, the fuse from this description is responsible for the fact that it is the maximum fuse (which is exactly what this fuse is responsible for). bus, which may be the reason that the battery is not charging (short circuit, maybe some sensor in the steering column). Please help

    You have a buddy BSI cabin module diagram, i.e. according to your description of the M001 box.
    Check if you have currents and masses everywhere. If everything will be ok, it is rather BSi has died.

Topic summary

✨ The discussion revolves around a malfunctioning windshield wiper system in a 2004 Fiat Panda 2 VAN 1.1, where the wipers do not respond to the gear switch. The user initially replaced the steering console and confirmed that the fuse and wiper motor are functional. Temporary solutions included using a manual ON/OFF switch. Participants suggested checking for a relay issue, specifically in the BSI module, and provided diagrams for troubleshooting. Ultimately, the user resolved the issue by replacing two faulty relays in the BSI switchboard, restoring wiper functionality.

FAQ

TL;DR: Replacing 2 failed BSI wiper relays restored a 2004 Panda’s wipers for PLN 20; "the wipers are roaring." This FAQ shows how to test fuses, find the BSI, and fix no‑wipe faults. [Elektroda, electron24, post #17542699]

Why it matters: This helps Fiat Panda Mk2 owners diagnose dead or erratic wipers fast, avoid guesswork, and target the real fix.

Quick Facts

How do I fix Panda wipers that don’t respond to the stalk?

A proven Panda Mk2 fix is to replace the failed wiper relays inside the BSI. That restored full operation. How‑To: 1. Disconnect the battery. 2. Access the BSI module and locate the wiper relays. 3. Replace both relays and test. Parts cost was about PLN 20 in one case. [Elektroda, electron24, post #17542699]

Where are the wiper relays on a 2003–2004 Fiat Panda?

They are inside the BSI module, mounted just behind the cabin fuse box on the left side, by the bonnet‑release lever. Remove the lower trim, expose the fuse box, and you’ll find the BSI directly behind it. [Elektroda, electron24, post #18021830]

Which fuse should I check first if my wipers are dead?

Check fuse F43 in the M001/P21 fuse box under the steering wheel. Verify the fuse condition and feed with a multimeter before chasing relays or wiring. This sanity check can save time. [Elektroda, electron24, post #17460865]

What symptoms point to BSI relay failure rather than a bad stalk switch?

If the wipers ignore all stalk positions but run when you feed the motor directly from the battery, the upstream control path is at fault. That points to the BSI/relay side, not the motor. Replacing the stalk won’t help in that case. [Elektroda, electron24, post #17455404]

Do I need to remove the BSI to reach the relays?

The relays are within the BSI housing. Access and replacement involve handling that module and its connectors. If you cannot confidently locate or open the BSI, hand the job to a professional rather than "sculpt" a workaround. [Elektroda, piotrekwoj1, post #18025968]

Is there a Panda wiper wiring diagram and what should I check on it?

Yes. The shared diagram labels A20 (BSI), M11 (front wiper motor), S27w (stalk), and grounds G10/G22, with 5A/15A/30A and a main 70A feed noted. "Check if you have currents and masses everywhere." Confirm power at the BSI and clean grounds. [Elektroda, marfur30, post #17461007]

My wipers move 1 cm every 40–50 seconds only on speed 2. What should I inspect?

This pattern aligns with a control-path issue on the second-speed command. Focus checks on the steering-column switch and the BSI’s wiper relays and feeds. Inspect for clean grounds and proper voltage at the control side. [Elektroda, marfur30, post #17461007]

Can I drive without the wiper relays fitted until I buy replacements?

Without those relays, the wipers will not work. Do not drive if rain or spray is possible. Instead of temporary wiring, have the module serviced properly to restore safe, reliable operation. [Elektroda, piotrekwoj1, post #18025968]

Are there engine‑bay relays I should check (B001/P03 box)?

The engine‑bay box contains relays, but the wiper system logic and drive are routed through the BSI (A20) per the diagram. Prioritize BSI power, grounds, and relays before chasing engine‑bay relays for a no‑wipe fault. [Elektroda, marfur30, post #17461007]

How can I quickly prove the wiper motor itself is good?

Feed the motor directly from the battery through a fused jumper or temporary switch. If it runs, the motor is fine, and the fault is upstream in control power or relays. Restore original wiring after testing for safety. [Elektroda, electron24, post #17455404]

What did a successful repair actually replace and what did it cost?

Two failed wiper relays inside the BSI were replaced. The parts cost was about PLN 20, and the wipers returned to normal operation immediately after. This low‑cost fix is worth checking early. [Elektroda, electron24, post #17542699]

Voltage differs to chassis vs battery negative, and pulling the 70A fuse stops draw—what does that suggest?

That scenario points to ground path issues and a parasitic load on the main feed. One owner measured 14.15 V to chassis but 12.5–13 V to battery negative, with 0.05 mA at rest, and removing the 70A feed eliminated the draw. Inspect grounds and BSI‑fed circuits. [Elektroda, adamr24, post #19971790]
