SOURCE: 1998 jimmy 4 wheel drive problem

are any of the lites on the switch flashing? you may have a sticking 4x4 shift motor on the transfer case. with a helper, key on someone under vehicle at shift motor, one operating the 2wd button, give shift motor a rap with small hammer on metal portion of shift motor to see if you hear it trying to work. to access control module, remove plastic right kick panel and its right there. remove connector and inspect for corrosion or bad connection. also try park and neutral, may even have to be rolling a bit to disengage. let me know how you make out and will help further if i can. do you know what transfer case system you have? np1 or np4?

Use the Owner's Manual to manually go into neutral and reset to 2WD HI. But then look under the hood check the fuses or look for wiring that may have come unplugged.

'Hokay, so now my lovable '99 Jimmy which was having breathing troubles, is now having 4WD trouble. And I think it's just the switch on the dash board; when the truck starts up, the light in 2HI doesn't...


The transfer case is computer controlled. The only way to give you a definative answer for your question is to scan your Powertrain Control Module for fault codes and perform a system check while monitoring transfer case input/output data to see if the computer is recieving the signal from the selector switch. On most GM vehicles, if there is a malfunction with ANY PART

I just bought a 95 gmc jimmy 4.3 vortec with 4wd and underneather on the frontend differential there is a bar sticking out that is welded to stay out and my jimmy will not go into 4wd at all why and how do...


I don't know what the bar is for, but I can help you troubleshoot the 4wd. I have a 1996 4wd Jimmy. The 4wd didn't work when I bought it. Here is what I found. The vacuum lines at the rear of the engine compartment were soft and gummy and some were rotted. I replaced every vacuum line I could find. Hidden underneath the battery tray is a vacuum operated actuator that engages the front axle. This line was not connected at all. I popped the push button assembly out of the dash to make sure everything was connected and replaced the light bulbs. Installed the switch back in the dash and went for a test drive. Everything is now working as it should. Did the testing on a dirt drive. Never on dry pavement. There are also electrical connectors underneath the vehicle that must be checked. They are attached to switches on the transmission and the transfer case. Let me know if this helps you get your 4wd working again.

Truck won't go back in to 2wd from 4wd


I had a similar issue in that we couldn't turn the 4wd on no matter how hard we tried. We replaced the switches in the dash and the vacuum hoses on the switch on the transfer case. the vacuum lines were dry rotted and leaking. we had our mechanic do it and all told was less than 500 bucks labor and tax included.

I have some problems with 2000 gmc jimmy not sure if me or truck


If it is a Canadain built vehicle the law required the head lights to stay on while the ignition is turned on. I have owned 9 Jimmy and Blazers including your year of Jimmy and none of them ever amde a noise in the dash when I put the vehicle into park. The shifter only has an electrical line runnig to the light control and a cable which runs under the carpet to the transmission.

2000 GMC Jimmy Transmission Whine


Does it sound like a loud winding sound coming from the front right side? I have a 2001 Jimmy and the 4wd tries to engage when driving up steep hills and going at highway speeds. The actuator vacuum switch engaged when the transfer case vacuum switch sends the vacuumed air to the actuator. What is happening is their is either a leak in the vacuum lines, a faulty actuator switch, or a faulty transfer case vacuum switch. When the jimmy has enough air pulling in, the extra vacuum is trying to push the actuator switch in when it is not supposed to. It is a much cheaper fix than a transmission. GMC should have recalled the whole 4wd system on any of the S10's, the JImmy's, and Blazers.
