I have not worked on a Jeep Liberty before, but I have diagnosed and repaired lots of power windows. Since no one else has responded yet, I will tell you how I would approach this problem. I don't know your level of mechanical skill but most power window issues can be diagnosed using a test light and voltmeter. First, turn the key on and check the fuse that operates the power window in question. If this fuse checks good, my next step would be to verify power at the rear window switch. I don't know how they come out on a Liberty, but you need to access the electrical connections to verify you have a constant source of battery voltage, and that when you push the switch down, your ohmeter indicates continuity, or ground. If you have both 12 volts and ground at the switch, you'll need to remove door panel and verify this at the motor. If true, motor is bad. If you are missing either voltage or ground problem is upstream, usually at the master switch. The same procedure follows at the master switch--a constant source of 12v (with ignition key on) and ground on the other terminal when switch is operated. The connections at these switches also acquire a black-looking buildup on the metal contact points--clean these with a pencil eraser. Good luck
