My HWH leveling system in our 93 Grand Marquis has worked perfectly, both air & hydraulic , for the 14 years we have had the coach. After parking last Saturday , I started to level the coach using the Air system. The "Air Operation indicator light" illuminated then went out. The entire panel is now dead except the "level sensing indicator lights" and the "Travel Permissible" light. The boots inflate to travel height, so no issue there, just no power to the HWH panel. I have the original manual, ML7797 Manual CHA-K 8-90, but it offers no help trouble shooting the system. Are their fuses in the system? I can find no CBs open.

Try removing the panel to check if a wire or two have become unplugged. Unplug the wires and reattach them. This is possibly the easiest and cheapest fix, and is worth a try.
