My power windows are jerky, broken or are making strange noises!:
This would be a problem with your power window regulator, which is another weak spot in our beautiful cars. To access the regulator, remove the screws on your interior door panel, remove the protective wax-paper type stuff, and take a look around. You may notice that cables are loose, snapped or possibly even tangled. You may also notice a broken plastic white piece, which is often the cause of all our headaches.
Using this guide, you can replace the regulator on your own.
