I posted a while ago that all the lights went out on my 4x4, and it didnt work. After buying a new dash switch, and 2 TCCM's(thought the first one was done...) I decided to rewire the connections going to the TCCM. 2 of the wires where broken off, so I replaced them. But still a no go. Checked all the other ones, and they looked fine. So I found a 2005 blazer with 30 000km on it and took the plug plus 6" of wire from it. So as I was cutting and reconnecting the wires 1 by 1, I found my problem. One of the wires half way up (1 of the 2 orange wires side by side) was broken. Looks like someone tried to fix it before by super gluing the wire back to the harness. Well after 10 minutes of rewiring it I have 4WD again!!! Ive gone all spring with out off roading, and now im back in the game!

So if your lights go out, and the connection looks eroded, a wire may be off!

 

Super Glue!? Whatever happened to gold old fashioned duct tape or silicon? LOL.

 

I donno... from where I bought the truck....im not surprised....

 

You got a former super glue factory's company truck also? Small world!
