Hi , to everyone , could someone help with the draughts /cold air coming into our van(autotrail imala730) we have tried to find where it was coming in but failed i know there is a little from the seat belt hole where it comes through, but can't find where the rest are getting in. Was at Bridlington the other week and at night it was draughty !! so much so we ended up putting a blanket over the cab seats to try and stop it.
