Scion xB Power Window Failure Guide
Are your Scion xB’s power windows causing you grief? Has one fallen? Here is a handy guide to help you fix many of the most common problems.
Having working power windows is great, yet it is a major pain when they don’t work. Without another way to roll up or lower your windows, you will constantly have to work around the problem. Luckily, it shouldn’t be too hard to fix them.
Broken Window Regulator
One of the most common problems with power windows is a dead window regulator motor. This motor powers the window up and down. When it dies, the window will stop staying up. If your window lowers on its own and the button doesn’t work, replace the regulator.
Here is a general description on how to replace it.
- First, find a replacement part at your local Toyota dealer or online at parts.olathetoyota.com.
- Next, disconnect the negative power cable to the battery.
- Look over the door for all the screws holding the plastic panel on. There will be screws in obvious places like along the handle and not so obvious places like behind the speaker.
- With all the screws removed, pull gently on the plastic door to pry it away from the metal. One of the best ways to do this is with a door panel removal tool or a flathead screwdriver. Be careful since you can easily crack the plastic.
- As you pull the door off, you will hearing a popping sound as the door clips release.
- After the door is free, push the door up and away from the metal door. Pay special attention to find an electrical connection between the power door buttons and the inside of the door. Make sure you disconnect these items.
- Once the door is completely free, you will see a plastic shroud protecting the inside of the door. Carefully peel back this to reveal the window and window regulator motor.
- Comparing your new window regulator to the older model, you will be able to match up which side is up and see how it works.
- Generally, you will have to remove some screws and then swap out regulator units.
- Once you have the new regulator in place, reverse these directions.
Window Off Track
Another problem could be the window has fallen off track. With today’s vehicles, this isn’t a common occurrence, yet it can happen.
In order to check if your window has fallen off track, you will need to remove the door panel by following the instructions above. Then, inspect the window and slide it up and down paying special attention to the rails. You will likely spot the problem the more you play with it. The fix is dependent on what exactly your problem turns out to be.
Door Lock/Window Fuse
If both your door locks and your windows don’t work any longer, you most likely have a bad fuse. In the fuse box is a fuse that often reads “Doors/Windows.” Simply replace this fuse with a new one and your problem should be solved.
