Re: 4x4 problem
the quickest and easiest thing to do at this point, is to disconnect the battery and leave it for a few minutes. Reconnect, start the truck and try getting it back into 4high and then to 2wd. If its flashing at this point, out the truck in reverse and a slowly reverse and see if that get it out of 4lo.

Re: 4x4 problem
You are trying to get it out with the trans in neutral? Have you checked the connection at the transfer case, & or is there a fuse? Just some food for thought. Mine up to now has never given me any trouble but I do use it a lot.

Trans in neutral. It went into low when I pushed 4x high and I was in park or drive. Connections are OK on case...unplugged Both and they looked fine. When I turn the key to on, you can hear the tccm make some noise like a relay cycling. They want 125 at the junk yard for one.
