Body, Interior and Safety

The modules that run everything outside the powertrain and the chassis: lighting, locking, windows, the alarm and immobiliser, the instrument cluster, the climate system, and the restraints that fire in a crash. Two things characterise faults here. They arrive in clusters, because one module usually runs several unrelated conveniences, so a spread of odd electrical symptoms is far more often one fault than many. And they live in the cabin, which makes water from a blocked drain, a leaking heater or a perished screen seal a leading cause rather than an exotic one.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

  • The car — make, model, year and engine. The same fault behaves differently on each.
  • What you measured, not only what you replaced.
  • What actually fixed it — or that nothing did, which is worth knowing too.
