Rear passenger window won't roll up
Three possibilities: 1) Bad window motor; 2) Broken wire going to the door; 3) Bad solenoid The solenoid for the rear window is in the front door, and if you can hear it making noise in the door when you press the window up button, that's not the problem. Remove two screws - one a Phillips head in the read door inside pull (armrest) and the other a Torx #15 just under the inside door release lever, Then pry the interior door panel off; release the two door latch rods, unplug the electrical wire to the window motor by first unlatching it. Then being very careful, apply 12 volts to the two pins on the door side, positive to the first pin negative to the second; if nothing happens, reverse them, apply negative to the first pin and positive to the second. The window should run up, and if it does, (A) you know the motor's not bad, and (B) you know it's either the solenoid a wire is broken. But you already listened for the solenoid, right?
Part two: Window rolled up? Now you have to find the broken wire. Put the door back together, including that cheesy-looking piece of paper - that's what keeps rain out of the door interior! The broken wire will be under that rubber hose-like thing you see running between the inside edge of the door and the door jamb. Pry that back and look inside it - one of the wires will be broken and require repair by stripping insulation off, twisting the wires together, soldering them and wrapping securely with electrical tape. IF you're not familiar with this, find a friend who is, or pay someone - this repair will be cheap since you've already done all the diagnostic work!
