Door Jamb Light Switch For Changan CS35 Plus CS55 Plus UNI K UNI V

Your Changan should illuminate the cabin the moment you open the door. When the interior lamps stay dark or the dashboard insists the door is shut, you are likely dealing with a failed door jamb switch. This replacement contact sensor detects whether the door is fully closed or slightly ajar. It communicates directly with your vehicle's body system to activate courtesy lights and warning chimes.

Restore accurate door detection with a unit built to reference OE number 3758010-MK51. This precise designation ensures the electrical connector and mounting geometry match your existing harness perfectly. You will see immediate improvement in how your vehicle responds to opening actions, eliminating frustrating light failures or error signals. This sensor supports installation on either the left or right side, handling demands for your front or rear door configurations.

• OEM Reference: 3758010-MK51 guarantees exact alignment with your vehicle's original door latch assembly.
• System Role: Acts as a door open signal sensor to trigger interior illumination and body electrical alerts.
• Application Range: Confirmed for Changan CS35 Plus (2023), CS55 Plus (2023–2024), UNI-V (2023–2024), UNI-K (2023), and Eado Plus (2023).

While replacing the switch, disconnect your vehicle battery first to avoid shorting sensitive control modules. Clean the recess in the door frame before sliding the new sensor into place. Dust and debris inside the slot can prevent the internal lever from moving freely, which causes the new part to fail prematurely.

Choose one piece for a single door repair or order two pieces to replace matching pairs on both sides simultaneously. This helps maintain uniform response time across all entry points.
