I have a 2019 Wildwood with electronic jack- Just stopped working- I checked the fuse both near the jack and in the panel and those are fine- Any other tips/tricks to troubleshooting?
Disconnect battery. Then using the supplied manual handle, raise (or lower) to clear the down (or up) limit switch. Then try electrically again.

Possible the wire crimps failed. Go back to the fuse coming off the jack and press the wires back in. They just need to make contact for the jack to work.
Also make sure someone didnt install the normally black colored jack wire to the negative terminal. Easy to do because i looks like a ground wire.
Clean all terminals. The jack grounds itself.
If easy you can remove the switch on the jack. See if the switch is seeing 12v. Make sure the switch itself has continuity.
