Is there a way to tell what switch you have? Pre Recall or Post ? part number difference?
Assuming thats the seat base(hard to tell from the pic) but that would be exactly it.
Part number would be the easiest way to tell pre- and post- recall switches.
Out of curiosity what setting did she have the seat heaters set to when that happened?
I know in my personal vehicle I have 2003 Jetta Wolfsburg edition seats and the switches are cloth pre-recall switches. In my car 1 is warm(typical setting for long trips), 2 is very warm(typical setting for short trips <30 minutes), 3 is uncomfortably hot(cant keep it on this setting). And I've never dared to turn them up to 4 or 5.
