2004 chevy tahoe. 94000 miles. Driver Message center has "service 4wd" on. I can shift from 2hi, 4hi and auto 4wd OK but not into 4Low. I used a code reader to check the code. But no power to run the code reader. Found blown fuse and replaced. Code reader worked but would not pick up the 4wd code. Is the problem the front acuator, TCCM, or Switch Moter Sensor or the in-dash switch. Please help.
have the same problem?
