BrianZ06 Posted January 21, 2010 Report Share Posted January 21, 2010 (edited) I have a 02 2500HD 4x4 with the electronic 4x4 switchs on the dash. The last time i put it in 4hi it stayed their. The 4 wheel works fine , just will not go back to 2wheel. When you push the 2 wheel button it just lights up and returns back to 4 hi. Now when I push the button I can hear something engaging also. Also it will only try to do the switch over after you turn the key on and off ,after it is running it does nothing when you hit the buttons. I just replaced the dash switch with a new one which did not help. Been reading up on the actuator,solenoid,and a module now my brain is fried. .Any suggestions.

Squidward Posted January 21, 2010 Report Share Posted January 21, 2010 Same thing happened with my brothers blazer, replaced the switch and it worked for about a week and stuck again when the pos chevy replacement switch went out again. I dont know if that could be it or not even though you replaced it but ours didnt make any noises when you pressed it. Good luck man Quote Link to comment Share on other sites More sharing options...
iwashmycar Posted January 21, 2010 Report Share Posted January 21, 2010 I think my parents blazer did that once too. Try unhooking the battery yet...stupid i know but i think that is what 'fixed' ours... seemed like a fluke incident Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted January 22, 2010 Report Share Posted January 22, 2010 you have the actual switch on the transfer case and the one in the dash either could be bad Quote Link to comment Share on other sites More sharing options...

AJ Posted January 22, 2010 Report Share Posted January 22, 2010 it may just be the encoder motor sensor. i have replaced alot of those. to be sure though you need to have it scaned and the codes pulled. Quote Link to comment Share on other sites More sharing options...

This happened to my moms 2005 suburban, had the exact same symptoms. ~Matt Quote Link to comment Share on other sites More sharing options...
BrianZ06 Posted January 22, 2010 Author Report Share Posted January 22, 2010 motor on the transfer case..sounds like the switch is working fine What I hear when pushing the switch buttons on the dash is the motor in the transfer case ! correct ? Im thinking the actuator is bad now because I can hear the motor working and I know the switch is working. I think the actuator is locked up in one position. Does this sound logical ? I do not have any service engine lights on so can you still pull a code ? The service 4x4 light is on though. Quote Link to comment Share on other sites More sharing options...
Twistedrx7 Posted January 22, 2010 Report Share Posted January 22, 2010 Put it in N and then switch it back over to 2wd it should work fine. Quote Link to comment Share on other sites More sharing options...
BrianZ06 Posted February 2, 2010 Author Report Share Posted February 2, 2010 encoder motor senser was bad - cause dam mice got into the underhood fuse box and made a nest and chewed some wires to cause a short which was burning up the sensers. The truck sits in a pole barn most of the winter. I guess I need to take some steps to prevent this from happening again. Thought my cat was taking care of this but Im going to have to fire him and do it myself maybe just start the truck and move it around more. Maybe some decon ? under the hood . Open to suggestions if anyone has had a problem like this. Quote Link to comment Share on other sites More sharing options...
iwashmycar Posted February 2, 2010 Report Share Posted February 2, 2010 i was under the impression that people use moth balls to deter mice.... i guess they hate the smell and wont go near them.. also Bounce dryer sheets Quote Link to comment Share on other sites More sharing options...
