RepairPal has identified the most common problems with the Dodge D250 as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
The powertrain control module (PCM) may fail resulting in a lack of AC cooling. The lack of cooling could be caused by evaporator freeze-up due to the AC compressor staying on continuously or conversely, not coming on at all. Proper diagnoses of the PCM should be performed before replacing it for this concern.
Under light load, at approximately 2000rpm the engine could exhibit surging, bucking, or intermittent misfires. Our technicians tell us this could be caused by a mis-indexed distributor.
An intermittent fault with the electrical connection at the crankshaft position sensor may result in poor engine performance and/or a no start condition.
Erratic idle conditions which can include engine stalling may occur in warm to hot weather. Our technicians tell us that a new idle air control valve is available to correct these concerns.
The engine may develop a lack of power or stalling condition due to low fuel pressure. Our technicians tell us that this can be due to contaminates passing through the fuel pick-up screen resulting in fuel pump failure. If fuel pump failure occurs it is recommend to replace the entire fuel pump module as it includes both the primary and secondary fuel pump filters.
Diesel engines may develop a hard start or no start condition due to any one of the following issues: Low fuel pressure, air entering the fuel system, and loss of fuel system prime. Our technicians tell us that the rubber inlet hose at the back of the injection pump and the lift pump are common causes for these concerns. Lack of fuel to the injection pump can damage the pump due to lack of lubrication, when this occurs it is not uncommon to replace the lift pump, injection pump, and fuel injectors.
The fuse may blow repeatedly for the HVAC blower motor or the motor may stop working all together. Our technicians tell us that can often be repaired by replacing the blower motor switch with a revised switch and installing a wiring harness with a relay assembly.
The blower motor may operate erratically and the blower switch operation has a sticky or mushy feeling, the detents almost non existent. Our technicians tell us that the blower switch should be removed and inspected for overheating. This is common if the blower motor is frequently operated on high speed as the current flow through the switch tends to melt internal the components. Also carefully inspect all of the switch connector terminals for discoloration due to overheating and replace as required. A poor electrical contact at the connector will also cause the switch to overheat.
The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops. There is also a revised vacuum check valve available to address this concern.
Oil leaks from the valve cover gaskets, timing cover gasket, distributor o-ring, and rear main seal area are common. The leak at the rear main seal area is generally not the seal itself but the bearing cap to the engine block seal. An oil leak could also be internal to the distributor, if oil is found inside the distributor then the distributor should be replaced.
Engine oil seepage may occur at the oil filter adapter plate. Our technicians recommend to check the adapter plate for warping and replace the plate as necessary.
