N/S Mirror adjustment.

[AMGeed]

Now the weather looks to be on the up, its time I sorted my n/s wing mirror out. Last summer I was convinced that the master control switch for mirror adjustment on the drivers armrest was at fault, so I got a replacement and fitted it.
It was a pain to get the unit out due to very limited access, but after replacing it, I still cannot adjust the passenger side wing mirror from the drivers seat.
Nothing moves, although before I switched it off in the convenience menu, the mirrors both folded. I realise that is probably not connected with what I now question, is my drivers door control module faulty?

I don't have test equipment and I'm too dumb to test electrickery faults anyway. So my question is, could a faulty door control module be the reason I cannot adjust the n/s mirror from the drivers switch?
I assume, should I need one that its a simple job to change them over?

Oh, one last point. I'm experiencing the battery going flat after 4/5 days of non use. Could this be connected to the module as well?

Too late to edit my post, but I am having a senior moment

I meant to post it was the passenger side electric window I couldn't operate from the switch, not the mirror, although to be fair, that doesn't work either.

Any suggestions welcome

Just to close this for anyone having similar problems. A replacement drivers door control module has stopped the drain. 6 days unused and just started with no battery convenience function message displayed and 12.3v showing before starting.
