I've read alot of the same issues on this forum to no avail.Here'e what I've got.I can't get the push button 4wd to go into 4hi.It flashes,but will not engage 4lo works fine.I have replaced the switch on the dash.The ECM,TCCM,and the Encoder motor with the same results.I'am starting to really get discouraged.I checked the servo under the battery tray and it seems to be working fine.The vacum hoses look good as well.The only thing I haven't done is change the vacum switch on the transfer case.Any help would be greatly helpful!

Well about the only 2 things left to do are changing the front axle actuator and the t-case actuataor. Mine is having the same issue and those are the only two things i got left to do as well. Doesnt appear that they are that expensive of parts but they might be a pain in the kiester to get to. Might want to do a search on the site, i think ive seen some general how to's and other info on what ya need to fix.
