#40 of 50 4wd Problem Was Not Fixed By Dealer
Jan 14, 2012 (8:21 am)
As posted above (2 years ago), my4wd service light came on and would start jerking and running rough. I didn't fix as I could deal with the 2wd, but now that the TB is used by my daughter, I finally had my dealer fix the problem. The dealer diagnosed and replace encoder motor/actuator ($566.46) acouple of weeks ago. Well, it finally snowed and it worked for a day. It's jerking again in 4 Hi and 4awd and it is difficult to get back to 2wd after turning the switch back, but after while, it went back to 2wd. Plan to take back to dealer next week. Hope they can fix it this time. If anyone has an idea (including GM) I would appreciate it.

I have a 2003 trialblazer...we rarely use the 4x4 but just a few days ago we got some good snow and used the 4wd and all of the sudden I heard some sounds like if some gears were hitting with rocks!!

Was wondering if you had ever got your issue resolved. I've used 4wd a few more times than others and for about 4 months now it's been jerking and in the last two weeks 4wd service has came on. I've had my truck now almost 4 years and have put a lot of miles on it. Just wondering what solved your issue. I want to take it in to the dealer soon...

Hi, i have an o4 trilblazer that had a cracked transfer case np8, I replaced it with a used one, it came complete with shift motor and all sensors. When i switch it in to any mode awd, 4 wheel high or 4 wheel low. the light flashes on what i selected but then goes off, and the light on 2 wheel high stays on the whole time. The 4 wheel drive never engages.
