Toyota Corolla Power Window Problems?

Toyota Corolla power window problems? Here’s what you need to know.

Power windows are one of life’s greater conveniences. Not everyone has them, but if they do, opening and closing power windows is push-button convenient. What if you have power windows in your car but they stop working? Today, we’re looking at the Toyota Corolla, possible power window failures and solutions.

  • The first reason your Toyota Corolla’s power window could be broken is the one you want to check before looking into the others, because of a bad fuse. Checking and changing a bad fuse is the easiest solution for a power window problem on your Toyota Corolla. To check if the fuse is your problem, simply test your electric door locks. If these don’t work, either, then open your fuse box, whether in the cabin or under the hood, and replace the Door/Window Fuse. If your electric locks work but your power window doesn’t then you know there is a different explanation for why it is not working.
  • If the fuse is good, and the power locks work, you may have a problem with the power window switch or wiring. You’ll need a wiring diagram and DVOM (digital volt-ohm meter) to test inputs and outputs from the power window master switch or the individual power window switch on another door. Double check that the power window lockout switch is properly working. On the non-driver doors, you can swap switches from other doors to check.
  • The next troubleshooting you want to try for checking your Toyota Corolla’s power window is checking the window regulator. This motor commonly fails or dies, and when it does, you will likely see your window fall halfway down the frame. If you believe this is the cause of your power window problems then you will need to remove the door panel on your Toyota Corolla. To accomplish this, follow the next portion for repair.
    • First, pop the hood of your car to disconnect the negative power cable from your battery. This will ensure a safe work environment for working on the electrical and motorized parts in your door.
    • Second, search your door panel for all screws holding it in and remove them.
    • Third, remove the door panel with door panel removal tool or a flat-head screwdriver, carefully popping it from the plastic clips holding it on.
    • Fourth, you will probably see an electrical connection attached to the door panel that must be removed before proceeding.
    • Fifth, you may see a plastic covering protecting the inner workings of your door. Remove this as well.
  • If it is the regulator then you will see it clasped onto the window. To remove it, carefully slide the window regulator off the window. You may want to raise the window yourself, and tape or clamp it, during the regulator replacement process. Once you have replaced the power window regulator, reattach the window and the electric parts to test it.
  • If you know the problem with your power window isn’t the fuse or the window regulator, it very well may be that your window has come off track. Over time, the window rails on your Toyota Corolla may begin to fail. This will cause them to become loose, or worse, to completely fail altogether. If this is the problem, you will notice your power window is loose as well. To repair this, follow the five steps in the preceding power window regulator segment to remove your Toyota Corolla’s door panel. Once the panel is removed, you should be able to see the window tracks. If you do notice that one is broken or loose, you can try to fix them by shoring in the gaps. However, in this case you may need to seek professional assistance for the best repair.

Power windows in your Toyota Corolla make driving in a life quite literally a breeze. If they fail or begin to fail, it can bring upon an unnecessary headache. These troubleshooting steps and solutions should help bring you back to the glory days of cruising with windows down in your Toyota Corolla.
