2004 Dodge Caravan Problems
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.
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.
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.
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.
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.
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.
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.
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.
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.
Alarm activation on vehicles without security system
Engine Spark Knock May Occur Under Acceleration and High Temperature
Under heavy acceleration in temperatures above 80° F, an engine spark knock can be heard. The powertrain control module may require replacement.
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.
Belt Noise Due to Pulley Misalignment or Belt Tensioner
Misalignment of the accessory pulleys or a faulty drive belt tensioner may cause a chirping or squeaking sound while the engine is running. In If the replacing the belt tensioner does not correct the noise, the alternator pulley may require replacement.
