2001 GMC Jimmy, vortec v6, 48,000 miles, no auto 4wd, only 3 button, sat for last 3 years, Wifes winter vehicle, immaculate condition. With that being said I have read pages and pages of posts and have not seen a description like the problem I am having.... Hit 4hi blinks and goes solid as it should, hear the thump but front wheels do not appear to engage ( drove in the wet grass, turned steering and hit the gas and she wants to blow a donut and front wheels do nothing), next I tried 4lo and appears to engage, but when gas is hit alittle it almost feels like the truck slips for a sec and then engages, or I should say feels like it, as I don;t wanna gun it in 4lo. Also let me add the 2wd works flawless. Give me old chevy 2wd and I can tear it down and put it back together end from end, 4wd is something new... So any help would be greatly appreciated. Paying a mechanic is not a problem money wise... it is just really hard to bring myself to do it.

Hello I have the same problems again after driving in 2 wheel drive all summer I went to put the truck into 4 hi and engage buttons [4] were not doing a thing except to blick beyond the 29 sec period that it should take? I have changed both hubs over a year ago I did all the things suggested except change the computer at a cost 600.00 which I dont have right now- untill I have more money I manages to get the truck into auto mode then pulled the fuses????????????? so far it seems engaged I wont know till snow comes? has this been done by anyone?

I had the same problem. I was told to change the actuator, and the switch on the dash. Worked fine for a while and then wham it did the same thing again. So I took it to the chevy dealer and had them put it on the machine to determine what was wrong with the 4 wd and the machine came up with the encoder motor. Just replaced it and it is working the best it has ever worked. They are pricey but found a great supplier over the net for a third of the cost. My suggestion is to take it to a chevy dealer that can put it on the machine. Takes about an hour but it is worth the hassle. Hope this helps. If you would like the supplier I got the encoder motor from email me.

| My Gmc Jimmy keeps cutting off on me, I can be crusing on the hwy, road and it will just shut down. I will let it sit apprx 30 sec - 1 min and it will start back just fine, but will cut off on me again, seems like when I press on the gas pedal it acts as if the gas is not getting to where it needs to go (when the truck cuts off the signal I get is the battery light comes on) it did this also before I bought a new battery. I have a also replaced the fuel filters and the multi fuel port injectors. Can someone please advise this woman on her vehicle before I spend another dime on it., also it make this kind of 'changelink noise" when I press on the gas, and when AI sit at the light...Please Help... | |
 Just bought a 96 GMC Jimmy from a dealer auction the other day for a winter vehicle and found out the first time I went to use the 4wd in a wet field that the 4wd didn't work. The light for the 4Hi comes on and you can hear it make a sound under the vehicle like it's transferring into 4wd but still doesn't work, when I push the 4Lo button all it does is flash and I can hear it under the vehicle transfer back to 2wd when I push the button for 2wd. What could cause the 4wd not to work when I can clearly hear it transferring back and forth from 2wd to 4wd.
