Yeah, it may be a bad switch or faulty wiring harness. I have some other problems besides the wiring/switch deal. When engaged in 4hi, the front pulls left then right, back and forth pretty strongly (yes, that's driving in the snow). I drained and replaced the fluid in the t.c. and front diff. I took it for a test drive on a thick gravel road and shifted into 4hi. I shifted fine and I drove it for a few minutes with all of the above described pulling. When I went to shift back to 2wd, it wouldn't happen multiple times pushing 2wd and 4hi. Just to see what would happen, I put it in Neutral, shifted to 4low...yeah that worked, just because it entrapped be into being stuck in 4low. I was close to the house by then so driving forward and back...pushing buttons...using manuals instructions to shift to neutral...pulling fuses....disconnecting the battery...it wouldn't go back to 2hi. I finally yanked of the dash piece surrounding the steering column, yanked and stuffed some wires because I was so ******, unhooked the 4wd switch and put it back together. NOW it is shifting again. I praised the Lord. One problem possibly figured out. Either a bad wiring loom or a bad switch. Hope that helped.

It is either the control switch or the actuator. look if light is flashing on push button switch. if so it is stuck. you can check actuator on front axle, to watch and see if it is moving.

2000 chevy suburban stuck in 4 lo anyone out that cant help


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.

Wont shift out of 4lo to any other 4hi or 2hi what can i do


Shot in the dark but I have done this before! Back up at least 50 yards in reverse with the selector set to 4wd Lo come to a stop, put your transmission in neutral, shift the 4wd selector to 4wd hi wait for a few seconds, shift it to 2wd hi wait a few seconds then put your tranny back into drive and see if that takes it out of 4wd. Good luck

4WD LO will not disengage what can cause this.


@ 2000 gmc: Exactly right.

asker: Also, it helps if you're rolling at about 2 mph with the steering wheels straight.
You cannot shift into 4LO with the wheels turned or when in a drive
gear. Also, it may be that you need the electric shift unit serviced.
It is not recommended to drive on dry pavement while in 4LO.

On my 2000 chevy S10 blazer, when I push the 4HI button, the 4HI and 4LO buttons flash a yellow light and it won't shift to 4WD, stays in 2HI and the light in the 2HI button is on yellow......I hear...


vacuum leak or vacuum locker solenoid problem. a great way to check for both is to remove both vacuum lines from the solenoid (located on firewall above destributor), and put a connector between them, push the button on the dash and see if it locks in.

My 98 chevy blazer won't shift into 4wd.


Most common problem is the vacuum diaphragm that is so inconviently mounted UNDER the battery tray.The cable that locks in the front diff is attached to it and vacuum pulls it in/out.

99 Blazer-push button 4wd not working


Make sure that all 4 tires have the same tread on them, if one or more of them are different, then the 4wd may not engage. I had the same problem with my blazer, I changed only 2 tires at a time. The front tires would rotate faster than the rear ones, the gears in the transfer case won't line up right.
