Hey! i have a 2005 chevy silverado 4.8 with autotrax and we had issues switching into 4wd found that changing the transfer case motor had resolved the problem, but now the truck will not switch again. Tried a new t case motor and dash lights just blinked indicating it was trying to change but didnt even hear any noises from the tcase motor. i tested the switch with a mulitimeter it worked fine. i removed the front axle actuator and manually set it to activate the front axle to be powered and had attempted to just be rid of the t case motor and manually switch the tcase into 4wd. but at every setting i try i cannot get the front wheels to spin. i had got the truck into 4lo but still no spin from the front tires. thanks much!

Probably your transfer case control module.TCCM is gone, They run around $130-140 USD. Probably less if its a reman unit..
