yesterday went out wheeling, now I dont have 4wd and the 4x4 high/lo lights flash 6 times every 2 - 3 mins. what does this mean other than I dont have 4wd.
So auto-loc hubs,1 button 4X4 1 button lo-range?, I would believe it's computer controlled. You where off road. I would check wires going to the transfer case for damage,also the hubs...
I was able to get it to go in to 4x4 hi and low last night while playing with the switch. the switch is a more like a ***, has 2wd, 4hi, and 4lo on it.
I was under it the other nite too, seems all ok. I'll have more time tonite and tomorrow nite to look at it.
certain conditions have to be met before the TC will shift, otherwise the lights will flash. Check your owners manual for the proper conditions for shifting. You didn't mention knowledge of this or whether the 4wd has functioned properly before so, just stating the obvious.
I had the exact same problem last week. After it sat for the night it was fine. I think it may be one of two things. Either the auto-hubs, or the electric switch. If we ever get some decent weather I"m gonna pull the electric motor from the tcase and clean up the connections, from what I've read this is a very common problem.
Search for previous posts related to this under my user name. I had the same problem. Replaced the T-case motor and it still didn't work. Finally reset the GEM and it's worked great ever since.
