1993 Dodge Ram Van B250 Problems

HVAC 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.

Erratic Blower Motor Operation Due to Overheated Switch

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.

Poor connection at crank sensor

An intermittent connection in the crank position sensor wire connector can cause poor engine performance or the engine may crank but not start.
