Use your multi-meter to probe each connector. Set the multi-meter for DC volts and put the prongs of your multi-meter into the connector. It should read 12 volts. Check the wiring on any switch that has a low voltage reading. Tighten any loose connections, and clear away any corrosion. Test another switch. Take a switch from another door and plug it into the connectors on the malfunctioning door. If you are able to operate your window using this switch, then the original is bad and will need to be replaced. Buy a new switch. Contact your dealership or favorite parts store and get a new window switch. Install the new window switch. This can be done by plugging the connectors into the switch and popping the switch back into the door panel.
A dirty or clogged engine air filter is more likely to reduce acceleration than fuel economy, according to tests conducted by the EPA. Because filters get dirty gradually over time, you might not notice a small but steady loss of performance until your car is accelerating like a turtle. But if you haven’t changed the filter in a couple of years (or sooner in areas that have a lot of soot in the air), that could be part of the problem.
