Question about 1998 GMC Suburban
I have a 98 GMC Suburban K2500 3/4 ton 5.7 engine, Auto, 4wd (Push Button) The Transfer case has just had a complete rebuild. I have installed a new dash switch for the 4WD, & also a new Control Module (Twice). What it is doing is the Service 4WD Light is stuck on & the truck is stuck in 4WD Low. I can hear it shifting when I try to change the position with the switch, but it blinks a couple of times and then the light goes on solid in 4WD Low.... ??????
The selector drive mtor mounted on the transfer case had alot of problems with water getting into the circuit board and also the mtoro drive getting stuck. At the dealership I have replaced hundreds of these over the years.

SOURCE: intermittent 4wd on 98 jimmy
the module is what i would suspect. and i do believe it is in the r kick panel. i've seen the button pack on dash go bad too, but module is best bet.

most likely needs an encoder motor. That is the fancy term for the motor that switches the t_case through the gears. The flashing lights indicate a code had been stored and you should have gotten it serviced then before further damage. as long as you dont drive it in 4 wheel you should still be ok

I have the same problem. It is intermittent and sometimes shows up with service transmission message. To get rid of it just put the truck in park, press the 2 high button and shift into drive while it is still flashing. I will worry about it more when it blows up. You can drive with the vehicle showing the solid neutral and it seems to make no difference. It has to be a wake up problem between the control modules. It only happens on start up.
