2003 Dodge Grand Caravan Problems
RepairPal has identified the most common problems with the 2003 Dodge Grand Caravan based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Due to a lack of lubrication, the AC compressor can fail. The AC compressor warranty was extended to seven years or 70,000 miles.
If the HVAC (heater) housing is not properly sealed at the bulkhead (firewall), water can leak into the passenger compartment. Foam sealant should be used to seal any gaps and the evaporator drain tube can be modified to prevent further water entry.
Hood misalignment, cowl cover misalignment, wiper module drain tube(s), and/or the lower plenum drain hose may cause the HVAC housing to leak water onto the passenger side floor. Diagnoses will be required to confirm the location of a water leak in the front passenger area.
The speedometer may become inoperative due to a failed vehicle speed sensor (VSS), . A failed sensor will require replacement.
If the transmission is slipping in first gear or Reverse—or if you experience delayed or loss of gear engagement after initial startup—the transmission may require removal and disassembly.
If you experience a harsh downshift from fourth to third gear, the transmission control module (TCM) software should be checked and updated if necessary before any other repairs are performed.
While turning in either direction during low speed parking lot maneuvers, if a creaking, squawking, squeaking, grinding, or groaning sound is heard from the front strut area, locate the front strut dust boot and rotate the dust boot side to side. If the sound is present, applying lubricant to the jounce bumper (bump stop) of both front struts can help with the noise.
A moaning or fog horn sound may be heard while turning at a slow speed. Installing a finned power steering cooler will help alleviate the problem, but it may be necessary to replace the power steering rack.
