ATC will not change to 2hi

When backing out or pulling into a parking space the rear end drags and now I cannot select 2HI from A4WD. It changes to 4Lo instead.

SOURCE: 4Hi won't switch back to 2Hi

First try hitting the 2HI when in nuetral. If that doesn't work put the vehicle in reverse and hit the 2HI switch and tap the brakes at the same time. Usual if you do this, when you put it into drive it will release.

SOURCE: 4wd stuck in 4Lo

Yeah, it may be a bad switch or faulty wiring harness. I have some other problems besides the wiring/switch deal. When engaged in 4hi, the front pulls left then right, back and forth pretty strongly (yes, that's driving in the snow). I drained and replaced the fluid in the t.c. and front diff. I took it for a test drive on a thick gravel road and shifted into 4hi. I shifted fine and I drove it for a few minutes with all of the above described pulling. When I went to shift back to 2wd, it wouldn't happen multiple times pushing 2wd and 4hi. Just to see what would happen, I put it in Neutral, shifted to 4low...yeah that worked, just because it entrapped be into being stuck in 4low. I was close to the house by then so driving forward and back...pushing buttons...using manuals instructions to shift to neutral...pulling fuses....disconnecting the battery...it wouldn't go back to 2hi. I finally yanked of the dash piece surrounding the steering column, yanked and stuffed some wires because I was so ******, unhooked the 4wd switch and put it back together. NOW it is shifting again. I praised the Lord. One problem possibly figured out. Either a bad wiring loom or a bad switch. Hope that helped.

The service 4wd light came on in my 2002 envoy.


There are two motors under the vehicle. The front axle actuator moves ONLY during 2HI->A4WD and A4WD->2HI transitions. The transfer case encoder motor makes a lower pitched noise in every mode transition: 2HI->A4WD, A4WD->4HI, and 4HI->4LO, and the three transitions upwards.

If EITHER of the motors fails to do what the TCCM commands it to do, the switch light will flash and the Service 4WD light on the dash will come on.

If you're a DIY mechanic, you might look into them further, or just take it to a mechanic who knows our systems. The average mechanic is not going to know the theory of operation of the trailblazer/envoy 4x4 system, which is pretty unique in the industry

Do I drive in A4WD or 2Hi?


Either one is fine I would use 2wd unless it is raining or snowy or you are on loose gravel. But you can leave it in a4wd all the time. In a4wd it will stay in 2 wd until the vehicle sees wheel slip, then it will shift into 4wd automaticly. If you have it in 2wd it won't shift into 4wd by itself.

02 dakota wont shift from 4hi to 2 hi


Try commanding the drive ranges while in netural cycling them. This may normalize the controller that senses the position from the encoder motor assembly. There maybe a procedure for that in a service manual.

You should be able to put in 4x4 while in drive less than 35mph. Mine had a switch to turn to engage or dis-engage.

99 Blazer-push button 4wd not working


Make sure that all 4 tires have the same tread on them, if one or more of them are different, then the 4wd may not engage. I had the same problem with my blazer, I changed only 2 tires at a time. The front tires would rotate faster than the rear ones, the gears in the transfer case won't line up right.
