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.
What are the signs and symptoms that might make you think your vehicle needs a tune-up? A misfiring engine (when spark plugs ignite at the wrong time) could be caused by worn or fouled spark plugs. Bad spark plugs can also cause low fuel economy, hard starting and sluggish acceleration. Most plugs, though, should last 100,000 miles or more, and engine computers do a remarkable job of compensating for worn plugs, so that might not be the main or only culprit.
