Bizarre Electrical Issue: Compartments lock themselves

Hi,
I just put my batteries back in my 2003 Itasca Horizon 40AD and now I have a weird problem. Every 10 of so seconds the compartments lock themselves.

Here's what I know so far:
- I know which ground wire I can disconnect from the battery to stop it
- the compartment lock switch in the RV cabin works - will both lock and unlock the RV
- the remote control does not work, but didn't work last year either

I'm really struggling to determine how to diagnose this. Anyone have any ideas?

Thanks,

Darryl

    OK,
    This is getting weird. The compartments lock in a pattern of almost exactly 10 seconds apart. I timed the locking and here is what I got:
    10.60 seconds
    10.67 seconds
    10.65 seconds
    10.63 seconds
    10.65 seconds

    This makes no sense!

    Some more info:
    - when I disconnect the one ground wire (very small one) it stops unlocking the compartments. However, the switch to lock and unlock them still works and will lock and unlock the compartments.

    OK, pulled the batteries out of the remote and that made no difference.

    If the switch was shorted, would it still work?

    OK,
    I disconnected all wires but the main ones and what I now noticed is that the 'Check antenna" light on the dash flashes every ten or so seconds. That light usually only lights up when the RV is started, and is solidly lit for maybe 10 seconds.

    One of the piece of info is that the RV started fin.
