Having 4wd issues, put a new encoder motor and 4wd switch in, it just continuously blinks going into 4 high, it goes right into 4 low, it sounds and feels like it goes into 4 low but doesnt actually enguage. Anyone ever experience this?

Just to confirm you are switching it into 4-low when the transmission is in neutral (foot on brake!) correct? With 190,000 miles on my 08 I fear I'll be having transfer case issues soon, if not already. I've gotten 2 codes for the service 4wd system thus far but am able to clear them and get into 4WD but that is only going to last so long. 1st priority is to get my rear pumpkin/diff looked into.
