S60 II T6 AWD – External mirror “freeze”

I must be surprised. I drove three years Renault from the sun-drenched France and never had any problems in winter. But now with the Volvo from the cool north, the exterior mirrors don’t work out any more, when it has snowed. Then you have to help manually. Not really bad but strange is that. For this I enjoy myself at the AWD on the snowy roads, on which the front-drivers drifted only helplessly.
