Typical HVAC symptoms owners report

  • The rear window defroster heating element overheats and causes the rear window glass to shatter, sometimes while driving.
  • Owners report smoke or burn marks near the rear defroster wiring and the rubber frame around the rear window before the glass fails.
  • In some cases the rear defrost button light fails to illuminate, leaving owners unsure if the system is even engaged before the window later shatters.
  • The rear defroster stops working intermittently, then activates suddenly with a loud noise followed by the window cracking or spiderwebbing.
  • A few owners report fogging or reduced visibility when the rear defroster fails to clear the window properly.
