The Saturn Ion, like other Saturn vehicles, has a rear-window defogger as a standard feature for driver safety and convenience. When your rear-window defogger malfunctions, however, it can cause a hassle and hazard while driving. Fortunately, many defogger problems can be fixed easily at home in less than 30 minutes using a $15 repair kit available at any auto parts retailer.
Tools Used: Tools, Multimeter (optional), Permatex or other defogger repair kit
