The parts you are listing are aftermarket items added by the conversion van company and will be on their own , separate, fuse block. Look for a secondary fuse block and I bet you will find it has lost power to the whole thing. Probably a main fuse to that block, or maybe a loose connection to it, you might have even disconnected it at the battery while “cleaning up†the wiring mess at the battery (assuming you or someone else did that). Good luck and keep us posted.
