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.
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.
