The electro-clear rear window defoggers contain a defect which causes the glass to shatter without impact during or some time after use of the defogger. Vertical electrical strips may deteriorate and cause hot spots that can result in breakage of the rear glass.
Vehicles will be inspected for presence of a particular weatherstrip. If present, a layer of a special conductive epoxy will be added to the vertical bar on the rear window glass. This epoxy is a new conductive material which will not react with the weatherstrip.
