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.

Most reported 2001 Dodge Grand Caravan problems
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.
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.
A problem with the sliding door track and door stops can allow the door to slide out of the track and fall off the vehicle. This is more common when doors are opened fast and allowed to hit the stops with a lot of force.
An oil leak from the oil filter adapter may be evident. Dodge has made a revised oil filter adapter is available.
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.
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.
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.
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.
On higher-mileage vehicles, oil leaks at the valve covers and front crankshaft seal are common.
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.
AWD equipped vehicles can show a wide range of transmission problems, often caused by using the wrong-sized and/or mismatched tires. Be sure that all the tires are the same and that all four are replaced at the same time. Dodge recommends tire rotation every 7,500 miles.
