The mechanics at work used the GM Tech2 scanner today and it came up as control module or something like that... Which i assume is the TC motor... He reset my ABS light (ABS sensor on front driver is bad) and it re-appeared immediatly... All fuses are good, there are no relays that we know of... We replaced a 20amp fuse for the "service" fuse (???) and the service 4wd light came back on... The new dash selector swith NOW shows the 2wd option lit... It doesn't change regardless of any other buttons pushed - the 2wd light stays lit... He's thinking it might be a bad wire somewhere or bad connections... I don't mind replacing the tc motor if that will fix the problem... We were running short on time tho today, so we will continue the research later... Just wanted to update the progress here... Any more thoughts after hearing this???

Wouldn't happen to remember the exact code would ya?
You say 'control module', so I would go in the direction of the Transfer Case CONTROL MODULE, more so than the encoder motor. It would be nice to have the code so we can steer you in a more deffinant direction.
