well, I started my truck today after work at 8 am and noticed that I still had it in 4hi and went to change it into 2wd and it never engaged or anything.... it sat there and blinked at me... the whole way home.... anyone know what it could possibly mean? I figured that it might have been too cold for it to shift and drove around a bit to warm everything up, but it still blinked at me. I'm back at home and the damn thing has been blinking for about an hour now. It's not all the lights, just which ever one you're trying to engage. I.E. 2wd--->4wd, the 4wd blinks. 4wd back to 2wd, the 2wd blinks. If anybody has had this happen please fill me in.
