Front Door Latches-Again

Back for more advice.
4 months ago when I purchased my 99' Range Rover I replaced both front door latches and everything was great until last night.
Last night went to Costco and of course it was rainning, and when I came back to the Rover both front doors did not respond when I tried to unlock and lock the Rover with the remote. :x
I know these go bad but so soon and both at the same time?
Could the rain be playing a factor with moisture to the motors or a short?
Also the dome light stopped responding when any of the doors are opened, inlcuding the rears.
When I purchased the Rover this was also happening but when I replaced both front latches it corrected the problem, or could this be an indicator of another underlying problem.
Did anyone find where the electric motors in the door lactches can be purchased, with the extended shafts?

I do have a strong advice from the french LR tech instructor (this guy wrote the French Rave and Bulletin Services)

Burning Door Latches are caused by non sleeping BECM, so have you RF receiver changed for the latest version XWY500170.

Do you have any battery drain?

Thanks, for the info guys.
I have left the Rover for long periods of time (1 week or so) and it always starts right up, so my impression is that I don't have battery drain.
Can you tell if the RF reciever is the latest version from comparing part#'s?
I will look at the RF reciever to see if it is the part# you metioned.
If you can't tell from comparing part#'s what should I look for?
My Rover is a 99' 4.6 with Bosh, I am located in North America if that also makes a difference.

I am very determined, we will all get to the bottom of this :!:
We shouldn't have to keep replacing latches, we should be playing in the mud driving circles around other vehicles.
In fact, you can't identify the RF receiver by part#'s, there's none.
Only way is to open it and compare with photos that are on a thread in there but search will be your friend. AllyV8 knows well the topic.
You should read about red light near the gearstick to see if the BECM goes asleep
