05 Supercrew Won't Go In 4x4
I went out tonight and my truck will not go in 4 wheel drive. I turn the switch to 4 hi and it doesn't light up on dash either. It only has 21,000 miles and I guess I'll be using the warranty. Has anyone had this problem? Thanks.

The first suspect is usually the electric shift motor on the transfer case. Number two is the IWE vacuum solenoid on the firewall. The shift motor failed on my 06 with less than 12k on the clock.
