Yep, Whenever there are snowstorms here my Bronco has snow inside the vehicle after that somehow blew through small cracks somewhere. Also when it is super cold the frameless windows stop working and also the 4x4 does not work either. Definately not designed for cold Canadian climate...
How were you able to spray the bottom 4 bolts? There is an insulation material inside those 2 slots on the inside of the tailgate so I cannot see the bolts and the insulation is blocking them. Thanks.
