For Citroen Nemo, Peugeot Bipper, Fiat Doblo, and Qubo models, replacing a faulty master switch is essential to restore full window functionality and ensure safe, convenient operation. </strong> As a daily commuter in the UK, I rely on my 2015 Citroen Nemo for short trips across London and surrounding towns. One morning, I noticed that while the front passenger window worked fine, the rear windows wouldn’t respond at all when I pressed the master switch. The driver’s side window worked intermittently, but the system felt sluggish and unresponsive. After checking the fuses and confirming the window motors were functional, I realized the issue was with the master switch control button itself. I began researching replacement options and found the part number 735518655, which matched my vehicle’s OEM specifications. I also discovered that this part is compatible with several similar models, including the Peugeot Bipper, Fiat Doblo, and Qubo. The key was ensuring the correct electrical pin configuration and physical fit. <dl> <dt style="font-weight:bold;"> <strong> Master Window Switch Control Button </strong> </dt> <dd> A multi-function switch module located on the driver’s door panel that sends electrical signals to the vehicle’s window motors.

The most reliable way to confirm failure is through systematic electrical testing and visual inspection of the switch mechanism. </strong> I own a 2014 Peugeot Bipper used for delivery work in the Midlands. After a few months of heavy use, I noticed that the rear passenger window wouldn’t respond when I pressed the master switch. The front windows worked, but only intermittently. I tried resetting the system by cycling the ignition, but the issue persisted. I suspected a wiring fault, but after inspecting the harness and confirming continuity with a multimeter, I ruled out electrical faults in the wiring. I then removed the driver’s door panel and examined the switch. The plastic housing had visible wear, and the internal contacts were corroded. When I pressed the switch, there was no audible click, and the window motor didn’t receive a signal. This confirmed the switch had failed. I cross-referenced the part number and found that the 735518655 switch is a direct replacement for my model. I also verified that it supports both right-hand and left-hand drive configurations, which is critical for vehicles used in the UK. <ol> <li> Turned off the ignition and disconnected the negative battery terminal. </li> <li> Used a trim removal tool to gently pry off the door panel without damaging the clips. </li> <li> Located the master switch and unplugged the electrical connector. </li> <li> Removed the switch from the door panel using a small screwdriver to release the retaining clips. </li> <li> Compared the new 735518655 switch with the old onesame pin layout, same size, same mounting points. </li> <li> Connected the new switch and reassembled the door panel. </li> <li> Reconnected the battery and tested all windows. </li> </ol> The new switch responded instantly. All windows operated smoothly, and the one-touch feature worked flawlessly. I also tested the auto-reverse function by placing a small object in the window paththe window stopped and reversed immediately, confirming the safety feature was active. The key takeaway is that a failing master switch often mimics a motor or wiring issue. Always rule out simpler causes first, but if the switch shows physical damage or inconsistent behavior, replacement is the most effective solution. <h2> Can the 735518655 Master Window Switch Be Used in a Fiat Doblo, and How Does It Compare to the Original? </h2> <a href="https://www.aliexpress.com/item/1005010487052483.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S90a8a70bad514fa0a3edb503a22014c2x.jpg" alt="735518655 for Citroen Nemo Peugeot Bipper Fiat Doblo Qubo Fiorino Car Accessories Master Window Switch Control Button 735461275" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> <strong> Yes, the 735518655 master window switch control button is fully compatible with the Fiat Doblo (2012–2018) and offers improved reliability and response time compared to the original OEM unit. </strong> I recently replaced the master switch in my 2016 Fiat Doblo, which I use for weekend trips and occasional cargo transport.
