Product Details

This Cardone Transfer Case Motor, part number 83-103, is built as a new O.E.-style replacement for transfer case systems that need reliable electronic shifting. It is used on applications such as the Chevrolet Astro, GMC Safari, Chevrolet Blazer, Chevrolet S10, GMC Jimmy, GMC Sonoma, and Oldsmobile Bravada. This part cross-references Chevrolet/GMC/Oldsmobile OE numbers 12474041 and 12547470 for the same application.

What It Helps Fix

• Service 4WD light illuminated
• Transfer case not shifting into 2WD or 4WD
• Weak or incomplete transfer case motor engagement
• Noise or inconsistent operation from a worn transfer case motor
• Failure caused by an original motor that no longer meets torque requirements

Installation Notes

Before installing the replacement motor, manually shift the transfer case into the 2-wheel drive position at the shift shaft. A crescent wrench can be used for this operation. Do not run the motor while it is off the transfer case, since that can damage the unit and set an error code that must be cleared before operation resumes. If the original motor failed in 4WD Low or High, install the replacement only after the transfer case is positioned correctly.

For 1998-2001 Chevrolet Blazer, S10, GMC Jimmy, Sonoma, and Oldsmobile Bravada, this part is listed for vehicles with a 2 terminal plug. For 1999-2005 Chevrolet Astro and GMC Safari, and for the listed 1998-2001 applications, verify the transfer case configuration before installation.

Quality Assurance

Cardone engineers designed and tested this new transfer case motor to match original equipment performance. Each unit is load-tested to confirm torque output meets industry standards, supporting dependable 4WD operation on compatible Chevrolet Astro, GMC Safari, and related applications.
