Your Cars Battery. Car's battery is a storage piece of equipment and is employed to start the engine. The battery helps activate and control the electrical accessories set up and installed on your car. The battery is composed of six cells of heaped positive and negative lead plates, divided by insulators and wrapped up in electrolyte, which is a mixture of sulfuric acid and water. The six cells generate 2.1 volts producing an entirety of 12.6 volts. This kind of energy is stored energy and not produced energy.
Use a multi-meter to confirm that the switch is getting 12V of power. Attach the leads of the multi-meter to where the electrical wires come into the switch and set the meter to DC volts. It should read 12 volts. Trace the wiring from the switch to the motor. This is the path that a signal will travel to move your window when you press the switch. Any breaks or loose connections in this path will prevent your motor from functioning properly. Use the multi-meter to confirm that the motor is getting 12V of power.
Between the electrolyte and the lead plates, a chemical reaction is created. This produces dangerous, explosive gases that vent through the battery cover vents. Because of this, caution should be taken when you charge or jump start a low battery. The same caution should also be taken every time you are working under the hood of your vehicle. It is important to provide as good ventilation as possible in the battery, so always keep it clean.
If your motor is functioning properly but the window is not responding, you may need to replace your regulator. Remove the bolts that attach the regulator to the glass. The regulator is the lift assembly that moves your window up and down. You will have to move the window up or down to align these bolts with a hole in the door interior. Using an extension on a ratchet, you will put a socket (usually 8 or 10 mm) through the hole and loosen the two bolts. Push the window all the way up. Use your hands to push the window up, and then either fasten it with tape or pull it out of the door altogether.
