Window Regulators

How to Diagnose and Replace a Kia Window Regulator


Bookmark and Share

If you find that your car's windows are stuck and you cannot move them, you may have a problem with the Kia window regulator. The window regulator is the mechanism that controls the movement of the windows in your vehicle. In most Kias, the windows are controlled by an electrical system. If you have an older model vehicle, there may be another mechanism that controls the windows: an older Sophia window regulator will likely be mechanically controlled by a turn knob on the inside of the door, for instance. For an electrically controlled regulator, you'll have to engage in Kia automatic window repair to get the regulator system working again. This process involves diagnosing the problem, accessing the equipment, and replacing any faulty components.

Step 1 -- Gather Up the Necessary Tools

In order to diagnose a problem with your Kia window regulator, you'll need to collect the following tools:

  • Screwdrivers
  • Prying tool
  • Voltage tester

Step 2 -- Diagnose the Problem

Check all four windows in the car to see if any of them work. If one or more of the windows will work properly, you do not have a blown fuse. For any of the windows that don't work, maneuver the switch to operate the window and listen for any motor sounds. If you notice the motor working but nothing is happening, it's possible a component is out of alignment in the system.

Step 3 -- Access the Door Panel

Use a screwdriver to carefully pry open the door panel so you can remove it from the door itself. The electrical wiring for the window regulator is positioned underneath the plastic covering on the door panel. Kia vehicles have a series of screws placed all around the door paneling you'll need to carefully loosen and remove. Keep careful track of these screws. Once you've been able to remove all of them, use a prying tool to gently remove the plastic paneling and set it aside somewhere safe. Finally, remove the clear plastic covering over the electrical wiring and place this somewhere safe too.

Step 4 -- Give a Visual Check

Look through the electrical circuit in the door paneling to see if you notice any damaged wiring or other visual signs of malfunction. Use a volt meter to check the electrical flow to the circuit.

Next, remove the regulator system entirely if you have to replace it. It is typically bolted in to the side of the door, so you'll have to remove the bolts in order to continue.

Step 5 -- Install the New Regulator

Follow the instructions on the regulator installation box to install in your door panel in place of the old one. It is crucial you purchase a regulator that is the same size and circuit type as the one previously installed in your Kia. If it helps to wait to purchase a new regulator until you've had a chance to see the old one and compare, do this.

If you have any questions about the installation, consult with a mechanic.
