4x4 does not work, traced system down. Wonder if actuator motor at bumper is air pump or vacuum. Motor does not come on. havent tried power to it yet. Trying to figure how this system works.
Hello, I would be glad to help you. The 4wd actuator is indeed air operated. IT has a pump that supplies air that is activated by the ECM. Click here for a very detailed description and basic wiring diagram. After you look at that let me know how I may help you in troubleshooting this.
