Do you mean all the windows won't work? Are you trying with just the master switch on the driver side door or did you also try with the switch located on the other doors as well? You can check the fuses for the windows. If the fuse is good and the window will go up using the switch located on the corresponding door I would check the master window switch. If it is just one window and it will not go up with the switch on either the door itself or the master switch, you may have a problem with the window regulator/motor. Hope that helped.

Check out answer I gave ozze2001 on this forum. There question was ( My driver side window won't go down. How can I be sure what's causing the issue.) I gave them step by step instructions on how to test window switch and motor and yes that is the correct procedure on how to check window problem that Stanford gave.
