Holiday Rambler Navigator HWH control panel location

Once you locate it, they are no longer available if defective. You have to send it back to HWH for repair. HWH, CAN repair them. Doug

Usually mounted up under the Drivers inside by the Brake pedal. This link shows what it looks like. About half the size of a shoebox and silver. Doug

PS what do you mean 400 Power Pack?????? HWH does not have a series 400 You mean a Ford performance upgrade?

Check and see if its mounted on the pump tray or right near by. I think it had a clear cover.
