2019 V90 the air con does not reach the cargo area. Any ideas about accessories to keep the dogs safe in hot weather, both parked and while driving? I thought the vents under the rear side windows would cool them but apparently they cool some other equipment near the tail lights. Has anyone even figured out how to make one of those silver colored sun block shades that will stay in the rear window when the car is parked? Anything I try comes flying down when the tailgate is lowered. Does the Volvo window kit #31439172 block significant amount of heat and can I drive with it? https://accessories.volvocars.com/en...CC-515997/2019
