I have a 2007 Chevrolet 2500HD. The transfer case is stuck in low lock. There is no indication of the low lock on the dash. The dash does say to service the 4WD. The computer shows no faults or codes. Any thoughts on the cause?

 

I would take it to the dealer. Is it still under warranty?

 

It is not under warranty and it was taken to a dealer. They scanned the computer and said that there were no faults of codes related to the problem.

 

t case actuator stuck already?

 

I had the same problem but in my old dodge. I don't know if this will help but check the wire bundle going into the TCase. I had one loose wire before and it sent a bad signal saying i was in 4wd.
