This transfer case switch directly replaces the original equipment switch on certain vehicle years, makes and models.

The 4WD system on certain vehicles fails when cracks in the actuator’s diaphragm create vacuum leaks. The diaphragm on this Dorman OE FIX actuator uses a mesh-reinforced rubber material to provide three times the durability of the original design.

The 4WD systems on many older Chevrolet and GMC trucks utilize a thermal differential actuator which is prone to sluggishness and failure when the wax that drives the actuator piston ages and deteriorates, ultimately disabling the 4WD system. This convenient 4WD differential actuator upgrade kit contains the key components required to easily replace the original equipment thermal actuator with a faster-acting electric actuator designed to provide longer, more reliable service. The kit contains our part number 600-101 4WD electric actuator and our part number 600-600 4WD actuator harness, both of which are carefully engineered to precise specifications to update an old technology thermally-activated differential to a more efficient electric differential on specified GM vehicle makes, models and years.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.
