If the car's dashboard battery light comes on, you might be able to make it home or to a service facility for a repair. The car will continue running as long as some juice is left in the battery, but if the charging system isn't working or you have a bad alternator, your car's engine will stop running once the battery is drained. If you turn off the engine, you won't be able to restart it if the battery doesn't have enough charge left to power the engine's starter motor.
Plug up the new motor. Plug the wiring harness into the window motor. This will provide power to the motor so use caution. Lower your window back into its correct place on the wiring harness. Remove the tape or re-install your window. Make sure that the tabs in the bottom of the window are properly aligned to bolt it back onto the regulator. Bolt the window to the regulator. Using the bolts you removed earlier and the same extension, you need to bolt your window back to the regulator. Test your window. It should now move up and down freely when you press the switch.
An old oxygen sensor (say, 90,000 miles or more) may still work well enough that it doesn’t trigger the check engine light but could still hurt fuel economy. Engine performance can also be reduced by more serious internal problems, such as valves that don’t seat properly or worn piston rings, or by restrictions in the exhaust system. Because the same symptoms can suggest different problems, and there are often several possible causes and cures, it’s better to consult a professional mechanic than to try to be one if you have neither the experience nor the right equipment to diagnose drivability problems. In short, rather than ask for a tune-up, tell a mechanic what you’re experiencing and ask him or her to find the cause.
Locate a replacement fuse. It must be the rated for the same amperage as the original fuse that operated the window mechanism. The amp rating should be printed on the fuse, and it should also be listed in your owner’s manual. Do not use a fuse with a higher amp rating, as this may lead damaging the electrical components of your vehicle. Push the new fuse straight down into the cradle. The fuse must be "set". This means that it does not move or wobble. Turn your car key to the "on" position. This provides power to your windows and allows you to test them. You need not start your car. Test your windows. Confirm that they go up and down without restriction.
