2003 Jeep Wrangler ProblemsWater May Leak From A-pillar on Side Doors
Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.
The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.
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.
