If all 4 are out and the rear window switches also do not work the issue is likely a broken ground wire in the harness between the driver's door and the A-pillar or the power window relay is not activating. We will verify the relay first as it's the easier of the two. Find the fuse and relay block on the left side of the dash. The power window fuse is in the same block. The relay is on the other side of the block. Remove it and use a jumper wire to connect the 5 and 3 terminals. Do the windows work? Yes, try swapping the relay with the one next to it. Windows now work? Relay is bad. Windows don't work, it's likely the ground wire in the door harness has broken. To get to that you open the door fully and then release the rubber boot that goes between the door and pillar. Then inspect the White wire with the Black stripe. I would also look at the others as well, it's a common failure because of the constant bending from the door motion.
