What a great thread!
I recently had to service one of my rear jacks, but not the screw, the actual 12v motor. So the camper had been on the truck for about six months, and we were out camping and I went to lower the two rear jacks for stability. One worked and the other didn't. The first thing I did was check the fuses and of course the rear passenger side was blown, so I replaced it, tried the jack again and blew another fuse. To make for a shorter story, after getting home from that trip I pulled the jack off the camper and removed the motor to find out that the coil wires were bound up by rust on/in the magnet or stator. Also, the white plastic cup around the motor had water in the bottom of it.
I took it all apart, cleaned and dried everything, put it back together and silicone all the seals and it works fine now. I'll probably inspect and seal the other three now too.
