Carol, I suspect you may have two problems. The first, and most important is that your house batteries may somehow have become weak. My rig does this once in awhile and I have to charge up the house batteries to make it work again.
The second problem is the top/bottom misalignment. You can drive it to the repair facility to have them look at this once you fix the "out" slide problem.
Now, to find the manual retractor, you are most likely going to have to look under the elevated portion of your slideout for the mechanism...at least that's how mine works...it's under the bed. You can get into trouble if you don't do it right, so be careful and READ the manual on this. There should be a bolt head on the end of the motor shaft you can turn, once you have disconnected the wiring as instructed. Since it's geared, you may have to turn it the opposite way you think you should. Good luck to you!
