How to Replace Summer Windshield Washer Fluid in Winter?

[VanMaximus]

If it's the same brand of windshield washer fluid, there's no need to drain the summer fluid - you can directly add the winter fluid as they are mixable. For different brands, first completely drain the summer fluid before pouring in the winter formulation. To remove summer fluid, simply hold down the windshield washer button until the system is emptied. Locate the filler neck (typically marked with a washer symbol and blue cap), open the cap, and pour in the winter windshield washer fluid.
