96 chevy 4x4. no ind lights. stuck in 4hi

Have you had codes checked ? While connected to a good scanner that will check transfer case switch to show if switch is working, and it could be the switch on the side of the transmission.

Put truck in Neutral while key in run position engine off or on (doesn't matter which). If it's pushbutton 4wd then try hitting 4low again. if that doesn't work some of the chevy trucks required you to press 4hi to get into 4high and then press 4hi again to get back to 2hi, unless yours has a 2hi button. In that case press 4hi to get into 4high and then press 2hi to get back to 2wd. either way you need to be in neutral to get out of 4lo. I have shift on the fly (Mechanical Shifter on floorboard for transfer case) on my 1990 Suburban and still have to put it in neutral to get out of 4lo. Good Luck.

It sounds to me like your gearbox is knackered, but just to be sure get underneath & check all the linkages, get yourself a workshop manual as linkages are easy to fit even for a novice, solenoids are relatively inexpensive so if you don't feel like doing this yourself then try this route first.

Please need more details. When that started, did you do anything to your Chevy before?

You need to have the dealer scan the control module to see what codes show in memory

i have a 90 chevy 2500 2wd 350ci.when i go to start my truck the key turns hard in the ignition,the check engine light and brake light come on the heater dont work,and the transmission will shift from 1-2 at real high rpm and shift hard,no 3-od.this comes and goes,but all happens at the same time.some times it last for 10 min,sometimes its days.what is going on?

do you have to truck in neutrul when trying to swtich back. some models you need to put it into 4 low then into 2 hi.

I would try to replace the switch. I believe that chevy had a bunch of problems with the 4x4 switch. I had a message on the display the something was defective with the 4 wheel drive, and it just ended up being the darn switch. Hope this helps.

Hi ..i had the same same problem in my k3500,check 4x4 fuse first .if thats blown replace it if blows when you put in 4x4 go under the car and unplug the actuator at the front diff.go back in the cab and put another fuse in, shift into 4x4 if the fuse does not blow this time you will need a new actuator.
thats what happened with mine and now 4x4 is sweet.i thought mine worked to at the start until i got bogged and noticed my front wheels wernt turning.

try reverse and push the button
