4x4 Help needed

[willy1094]

Sorry if this is a re-question. I have a 2001 silverado z71 and the 4x4 went out. It went out after having the frond drive shaft seals replaced (not sure if that could be connected). I had the solenoid replaced and it still would not work. Checked the wiring and it's gett current at the connections as far as we can tell. Now when I try putting it into 4w hi the light just blinks and nothing happens but it will go into 4w low. Any tips will be a great help from anyone. Are there any clips in the axel that may be bent or could it be the switch even though it seems like I'm getting power to the connection. Thanks!!!

I would say that it was put back together incorrectly. Was it a dealer? Take it back and have them check it.
