Mopar 5019639AA Blower Motor Resistor

When replacing the automatic temperature control module in Durango models you must install the power module instead of using a blower motor resistor by following the same mounting and replacing procedures. First detach the black wire connected to the negative side of the battery. Uninstall the blower motor resistor after removing its mounting screws and disconnecting electrical connectors and cover then reinstall it in reverse order. The blower motor replacement process starts with removing the kick panel on the front right side of the vehicle followed by disconnecting the electrical connector before unscrewing mounting screws which lower the motor from its housing. When the motor shows signs of damage it must be replaced with a new unit. The rear replacement steps begin with disconnecting the negative terminal and removing the right rear interior quarter panel and disconnecting the blower motor resistor connector followed by removing its mounting screw. The process to replace the rear blower motor necessitates professional discharge of air conditioning system refrigerant followed by disconnecting the refrigerant line fitting and pinching off heater hoses before right rear interior quarter panel and air ducts removal. Start by disconnecting the housing electrical connectors followed by removing screws that hold mounting fasteners before lifting the housing free. Following the removal of the blower motor connector disconnect its mounting screws and remove the blower motor from its position. The installation process requires reversing these steps while installing new O-rings that are specifically designed for R-134a refrigerant and using appropriate oil. The system should be evacuated then recharged and leak-tested before checking the coolant level.
