1998 Dodge Ram 2500 ProblemsHVAC Air Flow Switching to Defrost When Accelerating
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.
If the engine is difficult to start or cranks but does not start, it can be caused by a leak in the return side of the fuel system. This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak.
Some models could have a severe drift or pull to one side when the brakes were applied. If this is not caused by a dragging brake caliper, there is a service bulletin describing the step-by-step diagnosis and many possible solutions. Our technicians note the most common solutions are performing a four wheel alignment, checking torque on suspension components, installing shims between the wheels and hubs, and replacing the suspension arms.

1998 Dodge Ram 2500 RecallsChrysler Recalls 1998-2003 Dodge Rams Due to Short Circuit in ABS Control Module Connector
Chrysler has recalled certain 1998-2003 Dodge Ram 1500/2500 models equipped with four-wheel ABS because aftermarket batteries may leak electrolyte onto the ABS control module connector, which can compromise the sealing integrity. This may allow development of a short circuit in the connector, which could eventually lead to a fire. Dealers will inspect the ABS control module connector for electrolyte damage and replace it if necessary.
Chrysler has recalled certain 1997-1998 Dodge Ram 1500/2500 models equipped with Diesel engines because the throttle linkage joints can corrode and cause the throttle to bind or stick. This may result in a loss of throttle control, which increases the risk of a crash. Dealers will replace the rod ends and ball studs.
Chrysler has recalled certain 1994-1999 Dodge Ram 1500/2500 models in areas that use road salt because corrosion of the return spring on the hood secondary latch could cause the mechanism to bind in the "release position." This may cause the hood to open unexpectedly. Dealers will replace the secondary hood latch.
