1991 Dodge Caravan Problems
Speedometer Not Working Due to Failed Vehicle Speed Sensor
The speedometer may become inoperative due to a failed vehicle speed sensor (VSS), . A failed sensor will require replacement.
Door Adjar Light May Turn On and Chime Will Sound While Driving
The door ajar light may illuminate and chime during driving, even when the sliding door is closed. Often, this is caused by a faulty switch in the C-pillar; a revised switch is available.
Voltage spikes can damage relays
Voltage spikes can cause erratic behavior in the electrical system (lights, locks, wipers, head lamps). This is often caused by relays. Inspection and replacement of relays is required; revised relays are available.
Airbag light may stay on due to water intrusion
The airbag warning light may remain illuminated while the ignition switch is in the "on" position. This can be caused by water that has entered into the airbag six-way connector in the engine compartment.
Vent Window Latch Can Pop Open
Sometimes the vent windows' latch can pop open; if it will not stay closed or rattles, the latch assembly should be replaced.
Silding Door May Fall Off Track
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.
Engine oil leaks from cam plug and seal, valve cover, head gasket, and distributor
Common areas for engine oil leaks include the camshaft plug, camshaft seal (sprocket end), valve cover gaskets, cylinder head gasket and distributor.
Rear AC Not Cold Due to Refrigerant Leak
A refrigerant leak at the rear AC expansion valve and/or AC evaporator seals may cause the rear AC not to work.
Braking Ability May be Compromised
A defective anti-lock brake system (ABS) pump and/or leaking piston seals in the master cylinder can cause excessive pedal effort, lack of stopping power, and abnormal pump noise. Diagnoses will be required to determine the root cause of any braking issues and the component(s) that will require replacement.
Rear Lift Gate Does Not Stay Up
The rear lift gate support (prop) attaching bolts may break, causing the lift gate to fall unexpectedly. Thorough inspection of the bolts is required; if the support washers are loose, the supports need to be replaced.
Excess Oil Consumption Issue
Excessive oil consumption—defined as more than one quart per 1,000 miles (on vehicles with less than 50,000 miles) or more than one quart per 750 miles (on vehicles with more than 50,000 miles)—is common. Common causes include exhaust valve guides, valve cover gaskets, camshaft plugs, camshaft seals, and crankshaft seal.
Airbag light may be on due to blown fuse
Triggered by a short in the rear wiper motor/circuit (which causes a fuse to blow), the airbag warning light can illuminate erroneously.
