2002 Dodge Grand Caravan
Underbody Coolant Leak
Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe. Some 2005 models are involved in a special service action, no government recall was issued.
Odor from HVAC vents
Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.
Noise in Front Suspension Due to Worn Sway Bar Bushings/End Links
Worn sway bar bushings or sway bar end links may cause a rattling or clunking noise from the front suspension during low-speed driving. Though not always the root cause, front struts are often replaced for this condition.
Power Windows May Stop Working
One or more power windows may stop working due to a failed window motor or regulator. In some cases these items are replaced as a set. If not, diagnoses will be required to determine which is at fault.
Key May Not Start Car or Release From Ignition
Intermittently, the key may not start the car or release from the ignition. If it is excessively worn, replace the key. If the new key doesn't work, replacing the lock cylinder including tumblers should correct this concern.
Water Leak Due to HVAC Case Not Sealed at Bulkhead
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.
Moan/Fog Horn Sound May Be Heard While Turning at Slow Speed
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.
Engine Oil Leak From Oil Filter Adapter
An oil leak from the oil filter adapter may be evident. Dodge has made a revised oil filter adapter is available.
Auxillary Heater Hose Connections May Develop Coolant Leaks
The auxiliary heater hose connections (that are routed to the rear heater under the vehicle) can develop coolant leaks.
Head Lamp Switch May Fail
A failing head lamp switch can cause the head lamps and/or instrument cluster lighting to flicker or dim. The head lamp switch should have a noticeable click between each position; a "mushy" feel is a strong indication of a failing switch.
Shutter when turning at low speeds
Abnormal Noise While Turning at Slow Speed
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.
Alarm activation on vehicles without security system
Compressor Failure Due to Lack of Lubrication
Due to a lack of lubrication, the AC compressor can fail. The AC compressor warranty was extended to seven years or 70,000 miles.
Surging While Driving Between 40 and 50 MPH
V6 engines may experience surging while driving. The condition is more noticeable between 40 and 50 MPH while accelerating up a hill/slight incline. Replacing the powertrain control module (PCM) and updating the transmission control module (TCM) software may be required.
Transmission May Fail Causing Slipping in First or Reverse Gear
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.
Power Lifgate Module Software to Correct Erratic Remote Button Operation
If you have to press the remote button numerous times to open the power liftgate, it may be necessary to update the software in the power liftgate module to correct this issue.
