My guess, your transfer case doesn't want to work. Thats all I can think of.

Good luck

Drive slowly forward. remove your foot from gas pedal. Try to engage when rolling forward.



Confirm the cable to the front axle is engaging. I've heard they rust out when used very little.

i have the same problem and mine is at the dealer now, i'll post up when they tell me whats wrong.

sigh... well its the motor...expensive as hell.

i tested the motor by removing it and addind 12 volts to the signel on it and it works , but in the car it wont work . also i have done the going slow and ot did not work...

mine I'm told was still clicking like it was going to work if put back in the truck but it wouldnt do it's job. So as soon as they replaced it, it worked perfectly.

I hope you find whats up with yours...

Check your wiring in the car with a voltmeter. Could be a broken or worse; partially broken wire or connection.

how much did ur cost at the dealer
