I had the same issue with my truck, the switch was the problem.

I solved my issue by process of elimination which started with the switch,,, easiest thing to replace first.

How do I put my Chevy trail blazer 2005 LS in 4 wheel drive


look on the dash for a 4wd button or switch. may be located between the steering wheel and the radio. when you turn the knob to select 4hi, 4lo, 2hi, or auto, the indicator light above the corresponding selection will flash until the shift has completed. if the light stays flashing there is a fault in the 4wd system

My 99 silverado 4x4 is stuck in 4LO. When I push 2wd, 4wd auto or 4HI it cycles through and returns to 4LO. I have replaced the shift module behind the dash, switch on the dash, transfer case shift motor...


You have to put the truck in neutral first then switch the 4hi and don't use the auto select. If it still won't switch you may have damaged the servo and need to replace it. Or worse damaged the transfer case. So try in neutral first and hope that works.

The Service 4wd light used to go on and off


Drive in circles, one direction then the other and it should come out...Gears get preloaded and will remain so until this load is released...

The engauge/disengauge control does not have power to overcome gear preload.

2002 Chevy Silverado clunking noice when shift from 2wd to 4hi


It is somewhat Normal Depending on how Loud the Clunking is. This is a Common Complaint on the Chevy 4x4's. I have verified this through the Dealerships here in Oklahoma and they all say the Same thing But, I am with you, They should go into 4x4 without that Clunk for as much as we pay for them.
