I have a 2001 Blazer and today I put the truck in 4 Hi to pull my boat out of the water. After I got the boat out I pushed the 2 Hi button, the light flashed several in the 2 Hi button then when back to the light in the 4 Hi button. I can push the AUTO 4 WD button and that light will stay on, but the truck still fells like it is in 4 Hi. I need help

Thanks,
Joe

 

I had that same problem with my 2000 blazer. It could be your TCCM (transfercase control module) which is located passenger side kick panel, your selector switch itself, vaccum actuator under your battery, or your shift motor which is located under your truck. I went through the process of elimination with mine and it ended up being the shift motor. I installed a new one and now it works fine. Hope that helps. Good Luck.
