I just got an 04 V6 sport that wont go into 4wd. No matter where I put the selector, or push the diff lock button, nothing happens. ( neutral for 4lo ) On the dash, the center diff lock light is always on, the green 4wd light blinks slowly, the VSC TRAC and VSC OFF lights are solid on. I have let it sit overnight with the battery disconnected then preformed the zero point reset. I replaced the front actuator with a confirmed working one, and confirmed that the ring moves freely. When 4Hi is selected I am not getting any power to the front actuator. The center actuator moves when power is applied to both sets of pins. but I have not confirmed that power is making it to this actuator from the vehicle. I took apart and cleaned the contacts of the selector switch, and it is in working order. I am at a loss. Do i throw in a new control unit? or start checking wire continuity? If anyone has experienced this issue before, any help would be much appreciate, thanks!!!
