Twin Sliding Door Lower Roller Wear and Locking Wiring Break
MinorBodywork & RustBecause the Tourneo Custom is frequently deployed on busy school runs, commercial taxi duties, and airport passenger transfers, the twin side sliding doors undergo heavy daily usage. The nylon-sleeved bearings in the lower guide hinge assemblies wear down from road grit and weight, causing the heavy door to sag, rattle over bumps, and gouge the painted sill guide channel. Concurrently, the flexible multi-core electrical wiring harness running into each door shears from repeated flexing, causing intermittent failure of the central locking actuators, interior step lighting, or triggering false door open alerts while driving.
Sliding passenger door drops and drags against the bottom door frame channel, Scored paintwork and bare metal showing inside the lower external body guide track, Sliding door fails to lock or unlock with the remote key fob or central locking switch, Intermittent side door open warning chime sounding over rough road surfaces
- Slide both side passenger doors fully open and closed, checking for smooth glide and effortless latching
- Check the lower sill guide track for nylon roller fragmentation, metal swarf, or bodywork scratches
- Test the remote central locking to ensure both sliding doors lock securely and alarm arms without error
- Inspect the flexible rubber wiring boots between the B-pillar and sliding doors for pinching or splits
