Disconnect the car fuse box from the battery and be careful with any sharp edges as you can get easily injured. Use a flashlight if necessary.

The primary source of this electricity is the vehicle's battery. When the engine is running, the battery is charged by a part of the engine called the alternator. Before it is distributed, the electricity travels through the fuse box, where fuses on each circuit prevent components from receiving too much power in the event of an electrical disturbance. Different wiring harnesses then distribute the electricity to the engine and throughout the vehicle.

Components commonly connected to the wiring harness include the on-board diagnostic computer and fuel-injection system of many vehicles, auxiliary lights and dashboard controls. The emissions system and similar electrical components also connect directly to the harness, as do turn signals and other required systems. On many automobile wiring harnesses, the connectors and wires that connect these systems swap out easily for quick repairs and replacement.

Now you have isolated the problem to the relay and only two things can be wrong: either the relay's coil isn't energizing (due to an internal broken wire) or the high-current contacts are being drawn together but no current is passing through (remember high-resistance connections?). If the coil is bad the relay must be replaced. If the contacts are charred, file them smooth.

A small electromagnetic engagement coil consumes on the order of milliamps means just about any switch can activate it.

Every car's electrical system is composed of a wiring harness that connects various computer, controllers, lights, actuators, motors and switches. This electrical system is intergraded throughout the car to communicate with each part using a central computer which runs the engine or main electric motor. The battery is responsible for supplying power to the car while the engine is not running but in electric cars the battery does all of the work while powering the motor. High amperage circuits are designed with larger components to handle the load without failing. Common maintenance includes inspecting electrical connectors that are visible including the battery cables.

You may be lucky and just have a loose wire and banging just right on something might get it to fall back into place, but most times electrical problems are not that simple. Vehicles built in the 60s and 70s had very few electrically controlled devices as most things were controlled through a mechanical linkage. In the 80s and early 90s many automobile manufacturers started using vacuum controlled solenoids to operate small things like switches in the engine or the vents on your ventilation system. Since then, just about everything has become electronically controlled and regulated. Most of the electronics in your vehicle will last a very long time and never be changed, but when something does go wrong it can be difficult to pinpoint the problem.
