i have a 2001 blazer zr2 it goes in to 4 heel drive on its own can some one help me fix this problem e-mail is masterrayne@yahoo.com

 

Do you have the 4-button (auto4wd) switch in the dash?

BTW, it might not be a good practice to put your email address on an open forum such as this. Internet spam bots can get it and start sending you ungodly amounts of spam!

 

Just curious as to wether this issue has been resolved yet? Mine is doing the same thing, I am thinking it is the control module but have not dug into it yet. For now I just disconnected the push button 4wd switch once I got it back into 2hi.
Is there a way to check the module and or switch?
Thanks in advance,
Mark
