Dorman - OE Solutions Transfer Case Motor P/N:600-804
If your transfer case has stopped shifting between high and low ranges and a seized motor is the cause, this Dorman transfer case motor (part number 600-903) is a direct replacement. It fits many vehicles, among them the 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy and 2002-2006 Chevrolet Trailblazer EXT. See the Buyer's Guide tab for the full list. The Dorman OE Solutions transfer case shift motor is designed to install and perform like the original motor. It uses a factory-style connector and is sealed for protection.
The transfer case motor is the electric actuator that moves the transfer case between ranges when you make a selection. Signs it may need replacing include a transfer case that won't change ranges or stays in one range. Diagnose the shift system before replacing anything, because switch or wiring faults can cause similar symptoms. If a seized transfer case motor turns out to be the problem, this unit replaces it.
