Ok so I need advice from anyone who will give it. I have a 2005 4x4 with 97000 miles and all of a sudden the 4 wheel stopped working, but sometimes randomly it will decide to work. All I can say is in 2 wheel the drivers side rear tire does not have power in drive but in reverse it does. when trying to engage the 4 wheel the transmission and front tire lights blink rather than stay light as they should, and the front wheels do not even attempt to move. When the 4wheel decides to work all but the drivers side rear wheel rotate in drive and in reverse all but the passenger side tire rotate. I know sounds messed I honestly dont have a fricken clue, I checked everything I could and everything seems fine. I was told it could be an actuator or something similar the could be iced up or just busted. Any help would be greatly appreciated. Thanks, Babo
