2004 Jeep Grand Cherokee Problems
RepairPal has identified the most common problems with the 2004 Jeep Grand Cherokee as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
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.
The remote keyless entry system may not function intermittently. Our technicians tell us revised software for the wireless ignition node is available which can correct this concern.
A small leak from loose charcoal in the charcoal canister (part of the Evaporative Emissions System) may cause Check Engine Light illumination.
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.
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.
A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.
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.
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.
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 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.
