Front disc heating in V60 2 only on passenger side in function

Moin from the north, Has anyone ever had the experience that one side of the front window heating was not in operation? It is now the 3rd windshield, is probably a bit more susceptible to damage. I deliberately dispensed with a heater and “only” chose the windscreen heating. The routes I put back are only +100 km, because that fits, even in winter (stands anyway in the carport).
