The ignition coil is the part of your car’s systems that provides energy to fire up the spark plug. This is a vital process, allowing the fuel in the cylinders to ignite creating the motion that drives your vehicle. When it is not working correctly, this gives rise to changes in the drive quality.

The indicator stalk is the part of the car’s control systems that is used to control your vehicles indication lights. It is usually mounted on the steering column, giving you easy access without having to remove your hands from the steering wheel. Most indicators have a mechanism in them that turns them off when the steering wheel is rotated in a contrary direction to the indicator light.

Your car’s mass airflow sensor is the part of the engine that’s used to monitor the amount of air used in the combustion process. The part is only found on fuel-injected engines and it works with the ECU to ensure that the right amount of air is being supplied to the engine, to ensure efficient combustion of fuel in the cylinders.

Your instrument cluster is the part of the dashboard that tells you what’s going on with your vehicle’s internal systems. It contains the speedometer, the rev counter and all the lights and status displays that warn you of problems such as low fuel and battery charge issues.

Every instrument cluster has a lifespan and will eventually wear out. It’s quite a simple problem to spot as the speedometer and other dials and gauges will stop moving and lights will not function, such as the full beam warning or the hazard indicator.

This will require the complete replacement of the window wiper linkage, rather than fixing an individual part. 

Everyone knows how an electric window switch works. You simply press the button and the window is either lowered or raised depending on which side you pressed. It’s therefore pretty easy to tell when this part is broken, as the mechanism will no longer function, locking the window in one position.
