2012 Jeep Grand Cherokee Problems

Water Leak and Sloshing Due to Clogged Evaporator Drain

The AC evaporator drain commonly clogs and causes water to leak onto the passenger side floor. A sloshing noise may also be heard from the water inside the heater housing. Decaying organic debris in the housing may cause an odor. A service bulletin (TSB 24-06-96) was released; it describes how to clean the drain tube without removing the heater AC housing.

Temperature 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 May Break or Melt

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.
