i own a 2000 chevy trailblazer with push button 4 wheel drive.recentlywhen i put it in 4 hi,it seems to engage fine but after about 15 seconds the 4 wheel drive service light comes on and the only way to get back in 2 hi is to turn the truck off and turn it back on and then hit 2 hi but, even i do this the system makes a loud pop when it disengages.this is my first 4 wheel drive and i don't know a whole lot about them.i hear a lot of talk on hear about drivetrain binding.is it possible this could be the problem,if so what can i do to fix this

 

As the trailblazer came standard with the Auto4wd option, you really need to have the TCCM codes read with a Tech2 or compatible scan tool that is able to access the TCCM.

 

ok i'll do that,i really think it may be a suspension problem though
