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.
Sometimes, what people bother so much about turn out to be problems whose solutions are extremely obvious. This conversely means that checks for electrical problems in cars should start at the most obvious locations; the battery being a good example. Sometimes, a case of a car failing to 'start' or something of that sort could be simply as a result of an electrical contact breakdown at the battery. Here all that is required in the name of auto electrical repairs is something as simple as filing the terminals that connect the car to its battery.
