Review on Enhance Your Vehicle's Performance with GM Genuine Parts 89059275 Transfer Case Four Wheel Drive Actuator and Encoder Motor by Matt Lewis

2004 Trailblazer LT (250,000 miles) sometimes toggled and then didn't toggle to Auto or 4 hours. The light will flash and the 4WD service drive on the dash will illuminate until the next restart. The Trailvoy website helped me a lot and I determined it wasn't an under dash switch or control module as I could hear the old actuator motor (under the driver's seat) trying to move the transfer case into position to bring but never got it. work. made. Sounds weak, but it still works. Replaced the old one with this block (instructions on youtube), basically the electrical connection and 4 13mm screws. Took about 1 hour and everything was easy except for the screw on top. However, this is not so important when using the extension. I hope this review helps those who have the same problem as me. The truck is suitable for winter.
