'18 Sportback, I'm tired of finding acorns and mouse droppings in the glovebox. Where do they get in? So far I looked at the cowl shelf at the base of the window, and it doesn't look like GM made any attempt to keep mice out. And there's a wire bundle going through the firewall behind the glovebox that also looks like they made no attempt to seal. But I can't see clearly where either of those places lead, and I'd think either one would produce a big draft in Winter, which I haven't noticed to be the case. Anyone familiar enough with the HVAC to tell me where to look?
