I use to put cardboard on the glass under the wipers, leaving the wipers laying on the cardboard to hold it in place. Unless it is raining, the cardboard does not get soggy, and does not freeze to the windshield and the wipers do not freeze to the cardboard. I lived in PA for 38 years so I have dealt with ice and snow. Then I wised up and moved here to Arizona. 70 degrees today..................sorry to tell you! You could also put a sheet of plastic between the wipers and windshield. You have to start with a dry windshield and wipers so the plastic or cardboard does not freeze to either.

Replacing the windshield typically does not require replacing the windshield wipers unless they were damaged during the windshield replacement process. However, it is always a good idea to inspect the windshield wipers for any signs of wear or damage, such as cracking or splitting, and replace them if necessary to ensure optimal performance and visibility during inclement weather conditions. Regularly checking and replacing windshield wipers as needed is important for maintaining safe driving conditions.
A bad relay switch will cause the windshield wipers to not turn off. Replace the relay switch and the windshield wipers should turn off.
