Intermittent one-touch window and door mirror problem

[PierreC]

My 2010 T6 developed 2 different but I believe related electrical problems over the past week:

The one-touch function on the front windows now only works intermittently. The rear windows are not affected, and if this issue occurs, it affects the window switches in both driver and passenger door - which rules out a malfunction in the driver door switch. It is also not the notorious "open automatically after closing" issue and the "reset" procedure for that issue does not resolve the current issue.
--
The second intermittent problem is that the mirrors don't fold when locking the car - but only when I press the button on the door handle (I've got keyless drive) - when I lock it with the remote control it never has the mirror folding issue.



So it seems that these apparently unrelated issues may be related - both are intermittent and there does not appear to be component failure in either case.

Any idea where I can start looking?
