It has 200,100 miles on it, Never serviced the tranfer case.....I had the vehicle since it had 45,000 miles..

All the shift lites come on for the bulb check....

Also I disconnected the battery for 5 minutes.....

I disconnected the vacuum hose last night (for the front hubs)....the next morning I pressed the button fo 2hi- it stayed at 2hi....drove about 1 mile after I made a stop at the gas station, it finally disengaged..

I will take to autozone to get the codes read.....

AZ will not be able to read Transfer case data or codes.

Find a good repair shop with a transmisionn/transfer case/engine capable scanner.
