Sudden frigid conditions around the Lower Mainland area could cause your car’s windshield to develop or increase the size of existing cracks. Glass expands and contracts due to temperature so it’s important to be aware of sudden temperature changes.
 
Never use boiling water to defrost your windshield. Instead, turn on the defroster and let the windshield warm up slowly. However, be careful not to set the defroster too high. Let the windshield warm up gradually so the glass isn’t shocked by cold temperatures outside and warm temperatures inside, which can also lead to cracking or developing larger cracks from ones that already exist.
