All wheel drive, only front wheels are working

I would suggest we start with checking for codes.

Once we know if we have codes we will have a better direction to go. Clearly this could be a number of things from a sensor issue to the transfer case has failed. You have a clutch in the rear end that is known for binding in turns but less likely to be the cause of this issue so again we need to start with codes to hopefully get more to go on.

One thing we need to confirm is that you have not recently changed 1, 2, or 3 tires. When you change your tires we need to change all 4 or it can cause the transfer case to wear out.

Let me know and we can go from there. Thanks
