 It can stay 70 degrees in there on a really hot day. Not bad at all. And so take a look at the door. Take a look at the weather stripping and see what kind of shape that is. While you're at it, too, you might as well just go ahead and do the lubrication of the rails and the wheels and different things like that. Like I said, they're very vulnerable during extreme temperatures. And you don't do it with like a WD-40. And you don't do it with grease.
