I have a 2003 Winnebago Journey DL with an HWH series 310 leveling system. The jacks will not extent and I cannot hear the pump when I try to engage the jacks. The HWH web site recommends checking the pump fuse in the control box and the oil level in the system's reservoir. I cannot locate either the control box or the fluid reservoir. Any ideas where to look.
