Verified for the Jeep Grand Cherokee

Jeep issued an emissions recall in late 2006 to update the powertrain control module (PCM) software on certain 1996 vehicles. As part of the recall, the catalytic converter will also be inspected for damage and replaced as necessary. To see if your vehicle is included in the recall you can visit the Jeep website (owners' section) that allows owners to input their VIN number and check the recalls on their vehicle.

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.

Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

External oil leaks from the valve cover gaskets, intake manifold gaskets (front or rear), and the rear crankshaft seal area are common. The rear main seal is an unlikely source. Normally, leaks in this area are from the bearing cap mating surfaces as well as the sealing surface between the oil pan and bearing cap.

During light to moderate braking, if you experience a vibration in the steering wheel, floor, or seat, or a minor pulsation in the brake pedal, installing revised front brake calipers may help. If the brake calipers are silver in color, they are up-to-date. If the calipers are black in color, the revised calipers are needed and should be installed along with new front brake rotors
