The most common cause is broken and frayed wires between the driver's door hinges. The best clue is the windows will often work momentarily when you open the door part way. If this doesn't work right away, open the door, then let it sit for a minute before trying the window switch again. Power windows are protected with an auto-resetting thermal circuit breaker. If two bare wires touch together, that circuit breaker could trip, then it takes up to a minute for it to cool down and reset.
On a lot of Jeep models the harness can be unbolted, then unplugged, and be repaired on the workbench. Pull the rubber boot back, then inspect the wires. If you find some that are broken, I'll describe how I repair them.
