Hey all, this is a great site and I hope someone can help. I have a 1999 Blazer. My Service 4 WD light came on, trans case stayed in 2Hi. Per the info from this site, I was able to borrow a Tech II. Code came up B2725, cleared several times and it kept coming back. I figured simple fix, replace mode switch on dash. Prior to replacing switch, I tried to switch into Neutral to tow behind my motorhome. Would not go into Neutral, instead went to 4Lo. Finally got out of 4Lo, now is in 4Hi. I replaced the mode switch. Still can not get out of 4Hi. Please help, this is my main wheels. Thanks, Randy
