Your Canadian location might be an issue, but perhaps check with Jim Frerichs as a repair option...  Dometic 4 button thermostat repair

So I  experimented and started disconnecting wires etc  and found that if I disconnected the phone cable connecting the two AC units ( I think...) the main AC runs, just not the bedroom AC. A temporary fix I m sure and I don't know if the AC will run all the time but it does cool us until we can get it looked at

Peter, Good job of detective work. 

Maybe get a 6 wire phone cable with connectors, it should be easy to find, make sure the ends are oriented the same as the original.  Flat cables usually have a ridge on one side for orientation.  Connect the two ACs, if they work it is most likely a connector at one end of the OEM cable or the other or the cable itself.

If there is enough slack cut off the old plugs and crimp on new ones, one end at a time and reconnect.  Pay close attention to the orientation of the cable and the plug, one end is likely different from the other.  If it doesn't fix it then a new cable is needed.

You may be able to use the old flat cable to pull a stout string through and then use that to pull the new 6 wire cable without a connector and then connect a new connector at the pulled end.
