It sounds like your electric trailer jack may have a bad battery or a weak ground connection. If the battery is too low, it simply will not have the required amperage to operate the jack but may have enough to power the other functions you mentioned in your question. I recommend testing the battery to see if this is the issue.

Next you can check the ground connection for the jack. Most likely, your jack will ground through the mounting hardware, so check to make sure that there is not any corrosion or debris that may causing a weak ground, thus leading to the circuit not being completed or just not as good as it should be.

If you are still not able to find the cause or remedy this issue on your jack, please let me know and I will be happy to look into this further.
