• How to Diagnose and Replace a Toyota Window Regulator

    A defective Toyota window regulator can really be a source of aggravation and certain inconvenience. Fortunately Toyota automatic window repair is not very difficult and most people handy with some basic tools can replace a Corolla window regulator (or any other type for that matter) in a couple of hours or less. In order to help you quickly accomplish the task, here is a easy to follow step by step guide on how to replace a defective window regulator in your Toyota vehicle.

    What You Will Need

    • Phillips screwdriver
    • Flat head screwdriver
    • Socket set wrenches or ratchet wrenches
    • Hex head wrench set
    • Electrical tape or wire caps
    • Wire cutters
    • Replacement regulator for your vehicle

    Step 1 – Obtain Needed Materials and Tools

    Visit your favorite local auto parts store (or go online) and purchase a replacement regulator for your Toyota. Make sure to give them the correct make and model so that the parts store can supply you with the correct part. Also, make sure to pick up any of the materials on the above list that you don’t have available.

    Step 2 – Remove Door Panel Cover

    Use the correct type of screwdriver to remove any screws from the door panel where the defective window regulator is located. Most of the time, the screws will be located in the arm rest or just beneath it. Also, you’ll need to remove any screws along the outer edges of the door as well.

    Once you remove all of the screws, use a large flat head screwdriver to gently pry away the door panel from the door frame. There are usually a series of retainer clips that you will need to remove in order to do this. To remove them, simply insert the screwdriver inside the hole where they’re located and slowly pry them out. Continue doing this until all the clips have been removed and then remove the door panel cover.

    Step 3 – Remove Door Handle and Handle Rods

    Next, you should remove the door handle and the handle rods that are used to connect it to the window assembly. In some cases you’ll need to do this before you can completely remove the door panel. The door rods may be attached to the door handle via a series of small nuts and bolts or even hooks or clips. Use the appropriate tool to remove them all.

    Step 4 – Prop Up Window Glass

    Next, you need to prop up the window glass and ensure that it doesn’t fall completely off the track of the window assembly. A 2 x 4 block of wood usually works well for this purpose. You need to lower the window glass so that you can gain access to the window regulator. Once the window glass is then lowered, gently place the 2 x 4 block of wood between the window glass and the door frame itself. It should be snug but not too tight.

    Step 5 – Remove Defective Window Regulator

    Now, remove any hex head nuts or bolts that attach the window regulator to the door frame. In most cases, there will be four bolts—two at the top and two at the bottom. Remove them and place the nuts and bolts aside. Then, unplug the wiring harness. If there is no plug harness plug, use the wire cutters and neatly cut the wires that lead to the regulator.

    Step 6 – Install the New Regulator

    Install the new window regulator and reattach the nuts or bolts. Then plug in the wiring harness or use your electrical tape or wire caps to reconnect the wiring.

    Step 7 – Re-attach Door Panel Cover

    Remove the wooden block, reinstall the door panel cover, the handle rods and the door handle. Now test the window. You should find that it now operates properly.
