It was a dark and stormy night. Snow has covered the entire car to a depth of several inches. It takes a few minutes to clear the snow, and by then the engine has warmed up enough to melt the frost clinging to the inside of the windshield, and has actually made inroads to the frost on the side windows. But the rear-window defroster clears only a narrow strip near the top and bottom the window, leaving a wide strip of glass as translucent as a barrister’s door, and absolutely no visibility to the rear.
A worse scerio: The rear-window defroster grid has packed it in completely, requiring you to either drive blind (bad idea), or resort to scraping the rear window clear with your trusty wooden-handled snow scraper (really bad idea).
Now what? This Instructable will help you identify and repair some of the most common rear-window defroster problems, as well as tell you how to avoid further damage to your defroster. Try these repairs yourself, and save money and be safe this winter!
