power windows

Im having a problem with the power windows the two on the drivers side work but the two on the passenger side won't . They work when we bought the car two weeks ago any ideas

What year is this Century? I'd start 1st by looking at the wire connections in the DS "Master Window" switch. It's The switch in the drivers door that controls all 4 windows. Make sure the wire connections to the switch are tight and also clean. Pull the switch out, turn the key to the ON Position, then try and operate both PS Windows with the switch out.....If their still dead, the switch is probably bad OR, No power from the switch is being sent to the PS window motors.
