Repairpal verified Jeep Wrangler problems
If water leaks into the passenger compartment and under the passenger side carpet, an heating, ventilation and AC (HVAC) drain hose is available.
The ABS light can come on, indicating an ABS pump motor circuit fault. This is most likely to occur in warmer areas (above 90° F) and usually after a quick stop, like a refueling. If no faults can be found in the pump motor circuit after proper diagnostics, there is a revised ABS control module which should correct this concern.
If a thumping or creaking noise is heard from the transmission tunnel area while driving over bumpy roads, a transfer case shifter repair kit is available which should correct this concern.
"False" trouble codes may cause erroneous illumination of the Check Engine Light. Updating the PCM software can often correct this concern.
Jeep issued an emissions recall in late 2006 to update the powertrain control module (PCM) software on certain 1997 - 1998 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.
A hum or moan can be heard when the AC is turned on if the system is not charged with the correct amount of 134a refrigerant (.9 kPag or 32 oz).
The AC evaporator may freeze after extended use of the air conditioner. The output may feel low due to the restricted evaporator. Once the ice buildup melts, the AC operates normally. A revised low pressure cycling switch is available which may fix this concern.
If a growling noise can be heard from the AC compressor while the AC is on, a revised compressor is available which should correct this problem.
A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.
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.
