One problem related to engine head gasket leaking has been reported for the 1996 Jeep Grand Cherokee. The most recently reported issues are listed below.
Apparently some failure occured with the Jeep that caused smoke to enter through the ventilation system. The compartment filled with smoke. The smoke had an arroma of electricity. Everything that consumer had running such as the blower motor/ac were turned off. Mrconsumer feels the vehicle design allowed debris to enter the air conditioning air box and come into contact with the blower resistor. This caused the debris to ignite form the heat source, also the engine gasket was leaking oil.
