2012 Jeep Grand Cherokee ProblemsTemperature Blend/Recirculation Doors May Fail and Cause AC Problems
Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.
Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
