Affected Component: VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:REAR WINDOW
- Summary
- Customer Satisfaction Program - Certain 2014-2019 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a power sliding rear window (RPO A48) may have areas of high electrical resistance on the rear defroster circuit. This could be caused, in part, by mechanical stress from opening and closing the rear power window, intrusion of debris, and use of the rear defroster. Over time, this condition could generate heat that could melt the areas surrounding the circuit. In rare instances, this heat could cause a non-propagating fire, increasing the risk of property damage or injury. Dealers will replace the buss bar covers and contact cover. If the rear window or sliding glass assembly appears damaged due to an occurrence of high electrical resistance on the rear defroster circuit, they should also be replaced.
