I had the 2002 Trailblazer TCCM problems with no light and and no shift. I replaced the TCCM with a used one and now the Service 4WD light comes on, the lights on the switch flash when I try to shift into 4wd and I can hear the actuator trying to shift but it won't shift into 4wd. What would be the logical next step?
Thanks
