The jack stands that raises the front of the trailer up and down just goes up and not down. Worked fine in the morning next camp site won't go down. Checked the switch and it seems ok. Only 2 wires going to the motor. I tried jumping power to each one. One makes it going up the other it goes up very slow. Any ideas?

I think up/down is like in/out with the slide. The motor two wires change pos and neg to turn the other way as set by the switch contacts.I had that with the slide switch. New switch fixed that.

You have one switch but two motors? One for each leg? When you say the one doesn't go up, do you mean it won't retract, or it won't raise the trailer? Check to see if you have full voltage to the switch, and from the switch to each motor. Do the battery/ies have a good charge?

He is talking about the tongue jack.

He is talking about the tongue jack.Subject says 5er. Same switch anyway, 5er or tongue. Motor rotates the other way around when you switch pos to neg. Switch contacts do the reversing.Trailer goes up when leg goes down. Switch says "extend" and "retract"https://www.ebay.ca/i/362927710299?chn=ps&norover=1&mkevt=1&mkrid=706-89093-2056-0&mkcid=2&itemid=362927710299&targetid=886208803905&device=c&mktype=pla&googleloc=9001605&poi=&campaignid=9561945096&mkgroupid=97795563346&rlsatarget=pla-886208803905&abcId=1063836&merchantid=137610957&gclid=EAIaIQobChMI4_CZ6Njb6QIVAb7ACh1g4wYoEAQYAyABEgJBifD_BwEEDIT--I think the OP did not reverse them when he jumpered them however he did that.

It didn't sound like it to me, it sounded like you never found the problem, you just rewired directly to the motor? I always like to know why there's a problem and do what I can to fix it. But that's me.

Good that your temporary fix works. Gives you a chance to trace down the problem at your leisure.

Now fixed. I got the motor tested and the switch tested both fine. The wiring had wires going from the switch to motor and to inside the trailer? So wired it directly from power to switch to motor and it works!

Well, if the switch and the motor are both "fine", it should work. How were they checked and determined to be "fine". Have you checked to see if there is voltage to the switch in both positions: "Retract" and "Extend"?

Help I have had the switch and the motor checked and are fine. Some wires go,to the switch and motor. Some go back into the trailer then come back out. There must be a bad relay some where in side.does anybody know where to look? I looked in the fuse box and did not see any relay looking like one you would see in a car. This is a 2014 jayco 26.5. Any help would be great.

Looked in the fuse compartment and did not see anything that looks likes a relay. I have a 2014 jayco 26.5 RLS 5th wheel. Any ideas where to look or is a trip to the RV repair shop?

Ok I replaced the switch and the same thing is there anything else besides the motor to replace?
Have you checked the gearbox and the bevel gears at the tops of the legs?
