Even with the correct tools and knowledge, the procedure involves:
* Disconnecting the battery: This is crucial to prevent accidental deployment. You need to disconnect the negative terminal first, and often wait several minutes to allow the system to fully discharge.
* Accessing the airbag connector(s): This often involves removing covers, trim pieces, and potentially even the steering wheel's center horn pad.
* Carefully disconnecting the airbag connector(s): These connectors are usually designed to prevent accidental disconnection but require careful manipulation to separate. Force can damage the connectors and potentially the airbag itself.
* Removing the airbag module itself: This step usually involves carefully releasing retaining clips or screws that hold the airbag in place. The procedure varies significantly depending on the year and model of the Fiesta.
Instead of attempting this yourself, take your vehicle to a qualified mechanic or an authorized Ford dealership. They have the proper tools, knowledge, and safety procedures to safely remove and replace the airbag. The cost of professional service is far less than the potential cost of a hospital visit due to an accidental deployment.
Attempting this yourself could lead to serious injury, vehicle damage, or an expensive repair bill. Do not risk your safety or the safety of others.
