Having done all the above once and found the step sticking again, I got fed up with it and made up a kind of inverted protective tray that covers the top, sides and rear (relative to the step) of the Omni box, then used Duck tape over all the exposed joins in the top of the Omni box, lengthened the cable and re-routed its entry through the rear facing side of the tray, using shrink on sleeving between the new length of cable and the existing flexible conduit. So, in the nice clinical environment under a motorhome, just in line with the front wheels, on a wet day it all stays nice and clean and dry - not! ![]() The cable enters through a top or rear casing slot, which on mine was less than sealed. The floor of the box is another sheet of PVC which also slots into the sides unsealed. You'll probably find that the top of the box is a steel plate carrying the motor abutting a sheet of rigid PVC, with tape (mostly!) over the joint, both of which slot into the aluminium extrusions that make up the sides of the box. The top to sides joints are not sealed. If it is a real mess, it may be better to drop the whole unit from under the van, dismantle it some more, remove the electrical connections at the motor, and take it away to do a proper job. What I guess you'll find is that there is is a load of grit inside the box, and all over the step guides at the sides of the box, which has simply jammed the step. Keep your fingers well away from the operating arms if you value your fingers, the mechanism is powerful and moves quite fast so involuntary amputation is not impossible! If you want to test that the motor is still OK - which I guess it will be unless your kick has done it a mischief - reinsert the fuse and give the control a gentle prod. You can then ease the step right out, leaving the operating arms behind. Next, carefully release these nuts/screws and remove them, and the bushes through which they pass. At around this point, it would be a good idea to remove the fuse to prevent accidental actuation! Once the plate is off, coax the step forward and you will see two crosshead screws in the top of the step towards its rear, with nuts below. Watch your fingers around the aperture where the step emerges, the concealed edges are almost surgically sharp! There is a neoprene blade below the step, which you have to fold up to pass it through the "letterbox" slot in the front plate. Remove these, and you can take off the front plate. If you remove the plastic shrouds at each side of the step, you will find two screws each end behind these. It is a nicely engineered little unit, let down by poor installation and bad sealing by Omni. ![]() It should come forward, albeit a bit stiffly. If you can actually reach the end of the step while operating the control, try gently pulling at it while activation the switch.
