Front Seat Belt Retractor Repair (Replacing the Complete Retractor Assembly)

If a front belt retracts sluggishly, sticks or does not lock, the cause is usually a dirty webbing, a twist in the pillar guide or a worn retractor spring. The retractor on Fiesta VI front belts is non-serviceable and has a pyrotechnic pretensioner, so the repair comes down to cleaning and inspecting the webbing and, if the mechanism is faulty, replacing the complete belt assembly. The exact procedure for this model is not documented in publicly available service materials, so below is the general principle that holds true for this generation.

Step by step

11 steps
  1. Check the webbing and the guide. Pull the belt out fully and inspect the webbing for twists, cuts, frayed edges, paint and dirt. Wipe the webbing with warm water and mild soap, with no solvents or chemical cleaners. Let it dry fully extended, without rolling it up or applying heat. Wipe the plastic guide in the pillar: the belt often sticks right there.
  2. Check retraction after cleaning. If the webbing retracts smoothly and the latch and locking on a sharp tug work, the repair is done. If the webbing does not retract, does not lock on a sharp pull or sticks inside the retractor, move on to replacement.
  3. Disconnect the battery. Remove the negative terminal and wait at least 10-15 minutes so the SRS system capacitors discharge. This is mandatory: the pretensioner and airbags are nearby.
  4. Remove the trim. Remove the lower trim of the center pillar (B-pillar): pull off the door weatherstrip along the edge and carefully release the plastic clips with trim tools. Then remove the upper pillar trim, first freeing the belt height adjuster guide. On the 3-door version you may also need to remove the side trim of the cargo area or the lower side trim.
  5. Remove the upper belt mount (the guide/slider on the pillar) with a Torx driver. Do not drop the bolt and do not lose the bushing.
  6. Disconnect the pretensioner connector on the retractor. The connector is red or yellow, with a locking tab: first push back the lock, then separate the halves. Do not touch the contacts and do not test the circuit with a tester or a test lamp: this can cause deployment.
  7. Remove the lower bolt securing the retractor to the body and the lower anchor bolt (the buckle/latch mount) if you are replacing the whole belt. Take the retractor out through the pillar opening, supporting the webbing.
  8. Install the new belt in reverse order. The webbing must not be twisted. Tighten all bolts with a torque wrench. The torque for seat belt bolts is usually about 35-50 N·m (26-37 lb-ft) (use the manufacturer's specified value for each bolt). Do not use impact tools, to avoid loosening.
  9. Connect the pretensioner connector until it clicks and engage the locking tab. Reinstall the pillar trim and the door weatherstrip.
  10. Reconnect the battery. Turn the ignition on: the airbag light should come on for a few seconds and then go out. If it stays on, read the SRS fault codes, check that the connector is fully seated and, if necessary, clear the fault with a scan tool.
  11. Check operation: pull the belt out smoothly (it should move freely), give it a sharp tug (it should lock), release it (it should retract fully). Also check the latch and the seat belt reminder sensor.

Common mistakes and warnings

  • The front belt retractors on the Fiesta VI contain a pyrotechnic pretensioner
  • Do not disassemble the retractor, open its housing, strike, drill, heat or drop it, or apply battery power to the connector: it may deploy and cause injury
  • Hold a removed retractor with the housing pointed away from your face and store it separately
  • Seat belts are passive safety components: if you have no experience working with the SRS system, have the replacement done at a repair shop
  • If the vehicle was in a collision where the belts tensioned, replace the belt assembly together with the pretensioner and check the other SRS components
