Unhappy Strange Power Window Issue - Please Help!

So this isn't my first time around these parts, but it is my first time posting anything... I usually find WranglerForums.com when I do a Jeep related search, and y'all usually answer my questions without me having to ask them... Sadly that's not the case today...

My Girlfriend owns and drives an '08 Jeep Wrangler Sahara Unlimited... Seems like a really long name... anyway, she is the Jeep person, not I. I respect Jeeps for what they are, and work on hers 'cause it makes her happy not to shell out all that cash.

My Problem:
Last night my Girlfriend goes out to put her top up, gets it all secured down, goes to roll the windows up, front ones roll up fine, but the back ones don't budge. (She said she heard a noise when she first clicked the switch, I've heard no such noise.) So I got out there, flip the child lock back and forth, try both sets of switches, etc. No luck. So I search online and I find a whole host of people complaining about the same (or very similar) issues... All they had to do was cycle the igniton a few times and the issue was resolved. Not so with me... I cycled, I tried key on, engine off, key on, engine on, accessory, drove it around the block and then cycled the ignition... Nothing... I was going to rip the doors apart and see if I'm getting power back to the window motor, but it started raining (looks like a hurricane coming through, ah perfect timing...) Anyway I black bagged the doors to kep the interior dry, and I can't go out and work on it, so I figured I'd turn to the "Jeep Gurus" and see what anyone has to offer...

Thank you to anyone who made it through my rant, and a double thank you to anyone who can help in any way... I'm so lost here, mechanics are my comfort zone, electrics are not...

I'd check for a blown fuse first!

I checked the fuses under the hood, there is only one for both sets of windows... I might be missing a fuse block inside the cabin (like there is in most all other cars), but as for the one in the under hood fuse block it is not blown, and it's one fuse for front and rear windows, so it doesn't make sense for the fronts to go up and down, but not the rears... Thanks for the thought though.. If anyone wants to direct me to the other fuse block (if one exists...) it would be appreciated as well.

Happened to me once. But I regularly take the doors off and put them back on. When it happened to me, I took the keys out of the ignition, unplugged the door harness and plugged it back in. Started the jeep and the window went back up.

DFW6ER, your a genious! Ha ha. You probably saved me 35-40 minutes in Diag time. I forget sometimes that I'm working on a Jeep, I can check the power at the nice little connector and not have to tear into the door. Anyone know which pins are going to be the power window wires?

You guys rock! Ha ha. Thank you for the wiring diagram, now both windows are up in time for the storm. I just jumped the window motors with a couple pieces of wire, which A. Eliminated the window motors as the source of the problem and B. Is going to make the Lady at least 50% happy.

Looking at the wiring diagram it appears that power comes into the main switch, and then from there out to the other switch, and the windows... So maybe it's an issue with that main switch itself? Could something have burnt inside that switch preventing power from going out to the other switch, and the back windows??

Could be main switch or pinched harness.

Time to get busy with the multimeter. LOL

Been a few weeks. After getting the rear windows up I put it on the back burner and ordered a new main switch. Got it in just the other day, and no such luck being something that simple. I'm pretty shitty when it comes to electrics, but I start Automotive school Monday! Ha ha. S maybe I'll finally learn how to actually use a multimeter...

Anyway... I'm reverting to her saying she heard a pop when they stopped working.. I never got an answer, is the fuse block under the hood the only fuse block?
