It snowed, there were several steep hills to climb because i live in Pittsburgh, I went from 4H at after about an hour of driving came to a stop, pressed the button for to 4L drove up a steep incline then drive the rest of the smaller hills about 3 blocks worth at around 15mph tops went to a store turned the truck off then when i got back in it started in 4x4 4L and will not come out.

I cant here the familiar humm-click sound of the actuators on the Transfer Case going off when I normally press the 4x4 button. I hate the Electronic T cases, but thats besides the point.

Im going to check the Relay first, then any supporting fuses, Then I will check the control module under the dash and run its test button cycle hopefully i get 4 red blinks, then i will go underneath and check out the case itself, maybe snow got kicked and caked somewhere, froze, and cracked some plastic and shorted? I know its a reach but aside from electrical issues it could be the motor which i hope its not.

Any advice on the matter is well appreciated.
Thank you for your time
