SOURCE: 98 Chevy K1500, four wheel drive floor shifter won't engage.

I had the same problem with my 98 z71, I put the floor shifter in neutral, and let the truck roll backwards a little bit, BE CAREFUL, with the floor shifter in neutral the truck will roll, regardless if the shifter on the steering column is in Park, use caution, make sure there is no one around your truck and you are inside of it and out of the path of doors and tires,

Without further diagnostics, it could be any # of causes, but these are notorious for bad conections at the transfer case encoder motor and /or the encoder motor itself.The motor,when replaced may need to be reprogramed.Be sure the switch and wiring are functioning properly as the encoder and/or related control module are pricy$$

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.

SOURCE: four wheel drive does not engage when button on

Sounds like a n electrical shift actuator is at fault. It would be located on the transfer ccase. Make sure the fuse isn't blown and the wiring is connected at the case.

Service 4 wheel drive message comes on and no lights for 2and 4 wheel drive come on. On my 2004 gmc


Often lights under a dash or indicators just blow out bulbs. If more than one thing isn't lighting and are centralized check fuses to see if its blown. Bulb or fuse. IMHO. MIGHT be a sensor on tranny too. Hope not.

Here's a video with detaile dinstrauctions and other people's fuse questions. New fuses?

When I shift manual shifter from 4 wheel drive back to 2 wheel drive, truck does not want to return to 2 wheel drive. Dash light goes off as expected. No service light comes on. I did put truck in reverse...


Just to confirm, you don't have an electrical 4WD selector; you have to move a shifter on the floor of our cab? If that's the case, I'd suspect that you have a linkage misalignment or malfunction that doesn't allow the 4WD selector to completely return to the 2WD position. Putting the truck into reverse and back to drive probably causes a jolt to the 4WD linkage which disengages the transfer case from the driveline. Check for slack or binding in the transfer case shift level linkage (clean and lube the linkage won't hurt).

1995 gmc sierra 4x4 shifter wont go in 4 wheel drive but will go in 4 low


my name is michael. You said it will go into 4 low but not into 4 hi. Have you lifted the truck to see if it is operational? Does your 4x4 light come on? Does it grind into either 4 hi or low? And one thing, has anyone ever taken the axle out on the right hand side? Please feel free to email me at MOFRACKY1@hotmail.com.

Four wheel won't engage


Theres a vacume dash pot under the battery box. It pulls a cable that engages the front diff. Put the vacume line and you'll have lights and four wheel drive. (it happened to my blazzer)
