2003 Winnie levelers

We could use some advice: We have a 2003 Winnebago Adventurer and can't get our levelers down. Therefore we can't open our LR slide as the RV sits crooked. We have asked everyone, including the Winnebago dealer where the box is for the levelers (so we can check the fuse) and each time we're told it's somewhere else. My husband can't find it anywhere and we hate to take it to Camping World for repair only to find out it's just a fuse. The levelers were working fine just the month before, and when we took it out again we couldn't get them down. The dash light signaling that the levelers are ready to descend doesn't come on and nothing happens. Does anyone at Good Sam know where the box containing the fuse for the levelers is? It's not under the stairs, in the other fuse box or behind the front driver's side wheel. We know where it's NOT! Anyone have any ideas?
