4X4 trouble...I love this site!!!!

I engaged the 4 HI when we had ice and snow. It was not changing back to 2 HI. I came to Automotive Forums and found my solution! I went out started the Jimmy, put it in neutral, pushed the 4HI button, the 4 HI and 4LO flashed and the 2HI light went back on!!!

Thanks!!!
