Those of us that have these modules, have you had an issues with them?
I have one, and one of the switches control the bathroom fixtures. When it works, it works as designed.
When it doesn't, it has a mind of its own. Are there any of the mini relays that may be causing this and are they replaceable?
My last dozen coaches just had switches- not the relays.

They reprogrammed a couple of my switches to work correctly after they just stopped responding. Your problem may of course be hardware but I suggest you give them a call.
Can you provide a picture of the main controller and a switch keypad? I have updated the programming of our Intellitec multiplex keypads when buttons have gone flakey. Yours may be a version earlier than our system though.
What do you use to do that? One of my buttons has stopped working but it's one I hardly use so no big deal but I'm curious. When M&M fixed others they said the code is proprietary. Of course that's a great excuse to charge more.
I bought a USB to TTL converter on Amazon: Amazon.com: HiLetgo 5pcs USB to Serial USB to TTL CH340 Module with STC... (http://www.amazon.com/gp/product/B00LZV1G6K)
You connect the 4 wires from the USB TTL to the 4 pins on the keypad. +12v, -12v, Tx, Rx. I can look for a picture later.
You use the software on your Windows laptop for your specific keypad from: Multiplex Systems (http://www.mikerobotics.com/Intellitec/Multiplex.htm)
The software will want the USB to be connected to COM1 so that may have to be remapped (Device Manager | Ports | Properties | Port Settings | Advanced... | COM Port Number)
Once you have this setup. You can connect to each keypad to export and save on your PC the current programming. I also ended up creating a spreadsheet to document the mapping of each of my controlled devices to the relays and separately a mapping for each keypad to device. This keypad to device mapping is what is used to enter into the programming software either starting from a downloaded keypad config file or starting from scratch. It's good to have a backup of each keypad. For some reason every few months we have a random keypad that loses the programming on a button or 2. I don't know if its related to a surge or occasional disconnecting of the house batteries for other maintenance.
If you need to do this, I would be happy to talk you through it and send you my spreadsheet file. Send me a PM
Way above my pay grade for all this programming spreadsheet, et al.
I am not sure but think that the 2004 coaches use a different system than the earlier 42 ft coach.
