'97 Sierra 1500 4x4. No trouble codes in transfer case control module. I can hear the transfer case shift. I can fell that the transfer case goes to 4 low. But push button indicator lights keep blinking - which means front axle is not engaged. I suspect the 'thermal actuator' is not working, and thus the front axle is not engaging. Sound right to you? Is something else more likely? Thanks, Cal
