Have a gmc 2005 sierra the 4x4 doesn't work. when I press the 4x4 button blinks a few times,and then makes like grinding sounds,it sounds that is coming from transfer case,but never engage and ligth goes...


Not good! there is a sensor in your transfer case that senses that you are now in four wheel drive if your transfer case does not lock in it will set a code and the light will flash and default back to two wheel drive. check the fluid level in the transfer case and front differential for a sign of internal failure. that is causing the grinding sound.

I just bought a 1996 Sierra 1500 and its a got a toggle switch on the dash that the guy said was for the 4x4 but it doesnt like to engage in 4x4 very well, sometimes it takes 2 seconds and sometimes it...


It's the transfer case motor.I had the same problem and replaced it, now it works great. Part is about $100.00 ( aftermarket ) .Ifyou are going to replace yourself you will have to remove front drive shaft and remove yoke from transfer case with an impact wrench for clearance to remove transfer case motor . When you put the new transfer case motor in make sure you line up slot with grove in transfer case motor. Good Luck.

Truck stays in four low. When two high is pushed it will shift into two high then shift (on its own) back into four low.


check the 4x4 shift solenoid on the transfer case make sure the wires are ok ,could be a bad solenoid

4X4 inop on 2003 GMC Sierra 2500HD


I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

1996 Yukon 4X4 Electronic Shift on Fly.


I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.
