ACDelco GM Genuine Parts 89059688 Transfer Case Four Wheel Drive Actuator with Encoder Motor

I like to stay with original equipment when ever possible. A quality product and installation was easy.

Worked perfectly…installed easily and it came in the correct position so was a breeze. Selectable 4WD works great again.

Plug ang play and it already in 4wd hi this transfer case encoder motor no need to put in neutral the transfer case. Good product.

I bought a Dorman that did not work at all to replace the original AC Delco unit. The resistance between the different circuits in there was about 2 ohms, this fresh AC Delco unit was less than half a ohm. I had to remove the aftermarket one and take it back, this is the only trustworthy one for the h2 Hummer. If you’re trying to shift your transfer case and the button flashes for about 10 seconds and does not change positions, it’s about a 90% chance that it is this shift motor assembly that is the problem. The transfer case modules and dash switches do not fail nearly as often.

Solve the issue with the Service 4wd message Hummer h2 2006
