Your windshield and extreme cold weather... MUST READ!

[Waterloo]

In the 20's here, just went out to start the truck, I saw the defroster was on, don't do that!

I turned it immediately to floor heat to let my cold interior warm from the floor up, as heat rises.

Here is why... If you have a stone chip or small crack in your windshield, do not run the defrost to warm the truck in this extreme cold, use the floor heat. If you don't, you risk losing your windshield. That little stone chip or small crack has the very real potential of spider webbing across your entire windshield from the sudden heat. It has happened to me in the past, and when I say it spiderwebbed, it went the entire length and width of my windshield, it looked like someone took a ball bat to it.

Just thought I would throw that out there, especially for you guys down south that normally do not see these temps.
