My rear electric stabilizer is not working.

You might have a mini circuit breaker at the rear near the motor on the stabilizer. Our TT does. It may have failed. Could be the switch - pull it out, see if there is 12 volts present and use a jumper to see if you can make the jack work. Could be a bad ground connection and easy to check with a multimeter. The mini breakers are usually auto-reset and if no 12 volts on either terminal on it, it's a faulty breaker (if wired before the switch as it *should* be).

I remember looking at a Lippert wiring diagram earlier this year and they call for a fuse AND a circuit breaker but I can't find the actual Lippert document at the moment. The diagram below is a Lippert diagram from etrailer. I would expect the ground connection to be near the switch or jack, not at the battery and it's anybody's guess where it is exactly. Fuse would be in case of a short and breaker for an overload. On a 2015 unit, I wouldn't expect a faulty motor and a bad connection or switch is more likely the culprit. The switch is DPDT and just reverses polarity to the motor.

We didn't have any fuses in our TT and the wire gauge was smaller than what Lippert specs. Our rear jack is actually wired in series with a mini breaker in the A-frame and the one by the jack. Don't expect your TT to necessarily be wired how Lippert shows it. Starting back at the battery, the tongue jack and 2 stab jacks should be able to still work if the mini breaker feeding the converter panel trips.

The rear stabilizer on my recently purchased Passport 195RB would not work. Traced it to a bad mini circuit breaker mounted on the frame rail immediately above the stabilizer motor. On my RV the breaker is wired after the extend/retract switch. It is a 6 amp breaker intended to protect the motor not the wiring.
