Moin, I have quite a curious problem. And although the window lifter switch passenger only opens the window but no longer closes it. On the driver side however, I can open it and close it. But when the window opens, the lighting of the window lifter switch (passenger side) goes out. However, if I lower the window on the passenger side on the driver side and press switches on the passenger side also down, the window stops. Only w If I let go of the switch on the passenger side, the window goes further down. Does anyone have an idea what this could be the ECU maybe? I don’t think it’s a mass error but I can’t rule it out now 100%. I thank you already in advance for your assistance.
