Wiring the Power Window System

Now you can begin wiring the power window system. Follow these steps:

  1. Connect the wiring harness to the power window mechanism. The harness should include wires for the motor, ground, and power supply.
  2. Connect the power supply wire to the car’s electrical system. You can use a multimeter to locate a suitable power source. Make sure to use a fuse and relay to protect the system from overloading.
  3. Connect the ground wire to a suitable ground point in the car’s electrical system.
  4. Connect the switch wiring to the wiring harness. The switch wiring should include wires for the up and down function, as well as the power supply and ground.
  5. Connect the switch wiring to the car’s electrical system. You can use a multimeter to locate suitable wires that will activate the up and down functions.

Testing the Power Window System

Now that you have completed the installation and wiring process, it is time to test the power window system. Follow these steps:

  1. Reconnect the car’s battery and turn on the ignition.
  2. Press the window switch to test the up and down function of the power window.
  3. If the window does not move, check the wiring connections and make sure that the power supply and ground are connected correctly.
  4. If the window moves in the wrong direction, switch the wiring connections for the up and down function.
  5. Test the power window several times to make sure that it works correctly.
  6. Reinstall the door panel using the screws and clips that you removed earlier.
