Couple problems with my drivers side doors (front and back); they both stick shut below freezing, and the drivers side lock won't even turn. I tried to unlock the car from the tailgate, but that was stuck too and the hatch lock would only lock the doors. Only the passenger lock was able to unlock the doors. The drivers front door also leaks a decent amount during rain. Is the weatherstripping a standard item or something volvo-specific? Is the freezing lock a common problem or a warning sign that that assy is going to fail soon?

Thanks,
Charlie
