If you have the door panel off, easy to check the switch...... disconnect the harness from the motor and attach a test light to the harness.....press switch down....it should light......press switch up....it should light.....if it doesn't light in both directions, bad switch.....
Easy to get window up.....with harness disconnected, get two jumper wires......connect the wires between the motor and harness, the opposite way they would normally go(in other words, have them come out of the harness and switch them going into the motor)...then press down and the window will go up....
