Most reported 1993 Jeep Grand Cherokee problems

 

Verified for the Jeep Grand Cherokee

Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

Loose or worn suspension and steering components can cause a wobble or shaking in the steering wheel. It may happen at a certain speed and subside as the vehicle accelerates through the range. Tire balance can contribute to this as well.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address 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.

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.

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.
