Two leveling jack will not go down

OK dougrainer I tried it with all four T handles opened and all four extended. I hit the store button and only the two that were working previously retracted and the two that were not working are now stuck in the down position. I hit the off button and turned of the ignition switch so I do not burn out the other two. I have not closed the T handles. I assume they are stuck because they need to be lubed or something? Now what? :)

Thanks!
