Ok, I was rewiring the speakers in my truck and 4x4 lights started blinking. I unhooked the battery for 10 minutes and plugged it back in and it was blinking still. I did the manual hub mod so I push the hub to engage it by the way. I noticed the passenger side was engaged and it wouldn't disengage so I removed the hub and it was really dirty. (I have cleaned only this side many times before). So I cleaned it and put it back in and I could engage and disengage it now. The 4x4 was still blinking so I turned my truck off, put it in 4hi and turned the truck back on and the light came on as if it was working again and I drove it around but I could tell it wasn't working. So I turned my truck off, put it in 4lo, and turned it back on, drove it around and it definitely wasn't working. So I turn the truck off, put it in 2wd, turn the truck on, and the lights start blinking again. What gives? I don't know what to do can someone please give some suggestions?
