    I do have the same problem.

  • Attknee Nov 26, 2008

    My problem is even worse. I have no lights on at all and when I switch to 4WD it does not kick in. My mechanic says that the switch or sensor has to be replaced. It's on back order. Hopefully it will solve the problem.

I did found it. The problem is the Front Axle Actuator Try this link that explain how to replace: http://forums.trailvoy.com/showthread.php?t=46356

You can buy a new one for around 75$ on ebay. Dealer was 300$ + 300$ to install it... Took me an hour !

    tried this fix and it did not. Still no front axles! Now pointing to Transfer case control module, or transfer case drive actuator. Both are $150 parts?

May be broken 4WD actuator (quite common) which has stuck between engaged and disengaged. Remove and inspect actuator, but first examine all linkage for damage or having come loose.

I would think the car is in 4Lo . You need to get it out of 4 Lo before trying to drive it on the road because you will blow it up trying to achieve high way speedsin 4 Lo. use the knob on the dash to get it out of 4=Lo

My 04 TrailBlazer LT popped up the Service 4WD light. I put it in 4WD this morning and had no problems. I went to lunch and put it on and it took a few minutes to switch and then the light came on. It...


MIne will do that only when I'm switching my 4WD to 4low or 4hi, or back to 2hi AND the TB has good traction, ie pavement or rock OR the tires are cranked to one direction. After my wheels are straight, I just turn the engine off, and turn it back on, then the light goes off. Mine won't do that if I'm in mud, snow, or dirt where there's no traction. My guess is that it may be binding when the traction is good, therefore, I shouldn't be in 4WD. Anyway, my 2cents and I don't think you have to worry about it.

You maybe have a bad switch and it's activating the actuator when it's not supposed to. Try unplugging the actuator by the front diff. See if that makes a difference.
