HELP power gear leveling jack rear jacks wont work

Hi Guys,sorry to bother you. I am having issues with my auto leveling jacks on my road warrior RWT.... of course right before the one time a year I use it. I went to retract the jacks and fronts came up no problem and the rear two did not. I got the error message for the back two jacks. I went under neath and shorted them out to bring them up. I also tested the magnet sensors and they are working correctly. Could it be my control module? It seems like they are impossible to find the power gear 140-1224 rev 0g as they have been discontinued. Is there anything else i can try? Any input is greatly appreciated. Thank you.
