4x4 module problem?
My 4wd light wont stay on when engaged in 4wd. The only time it lights up is when the transmission is in neutral, but when u put it into gear after switching to 4wd, the light goes out. I also can't engage 4wd while im driving down the road. If I switch it to 4wd it wont take it until I pull out the fuse and put it back in, then it will only work a few times and eventually will have to do the same thing again. I carried to a shop to have it diagnosed because I figured it either had to be the module or the computer but when they plugged into the system, it wouldn't let them read anything. They replaces the fuse and it still would not allow anyone to access it. I'm thinking this means the module itself is bad since that is where you have to access the diagnostic system. Has anyone had this problem or know anyone who has?
