Haynes Tech Tips - Overnight Freeze
Are you expecting an overnight freeze?
Pull your windshield wipers away from the windshield – most will lock in this position – it will keep them from getting stuck to the windshield.
Also apply silicone spray to all the weatherstripping. This will help prevent the doors and windows from sticking.
To keep your lock cylinders from freezing, lubricate them with WD-40 (that’s what the little red tube is for!).
