1990 Dodge Ram Van B250 Problems

Erratic operation of idle speed control motor
An erratic idle, stall on hot restart and/or low speed deceleration. may be caused by a faulty idle air control motor. Our technicians tell us there is a revised IAC motor to correct this condition.
High Blower Only Due to Failed Blower Motor Resistor

The HVAC blower may operate on high speed only. This is commonly caused by a failed blower motor resistor. Chrysler has released a revised part to address this problem.

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.
