Power Plus Electric Levelers

So my 1996 Georgie Boy Swinger is in Camping World Service center,,The main thing I needed was my levelers working,,unfortunately it has "Power Plus" leveling system who is out of business and no one makes replacement parts so he said on the phone they could not do anything with the levelers,,I guess now is the time to roll up my sleeves and trouble shoot on my own. What ever it is it is affecting all 4 levelers,,I get an out of level light indicator on the panel but when I push auto level the on off light flashes as it is supposed to but the jacks never move. When I try to individually operate them I get nothing,,no sounds, no movements, I get nothing, what ever is affecting them is affecting all 4 of them..Any Ideas??
Please, no snide remarks about CW as this one in Georgetown, Ky has been a great help so far,,Thank You
