1992 Dodge Ramcharger Problems
RepairPal has identified the most common problems with the 1992 Dodge Ramcharger based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
The engine my develop and buck, surge, or noise due to a worn distributor drive gear. If the distributor shaft has excessive rotational free play the distributor drive gear and bushing should be replaced.
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 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 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.
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.
Vehicles equipped with 12" diameter rear brakes may encounter premature rear brake shoe wear. Our technicians tell us that if the brake system is functioning as designed the affected brake shoes should be replaced with revised parts.
Cracking or popping sounds from the cowl area may be a result of cowl cracks at the lower corners of the windshield. The fenders must be removed to see the cracks. If cracks are found, a reinforcement kit is available to correct the condition.
A condition may develop where the fuel gauge reads empty with too much fuel still in the fuel tank. Our technicians tell us that installing a new wire harness that provides a common ground for the fuel gauge and sending will correct this issue.
