SOURCE: i have 1997 gmc jimmy sl5 it will not shift out of 4 hi

I believe that this vehicle has a vacuum controlled solenoid on th edrivers side of the transfer case. This solenoid could have lost vacuum by having a broken vacuum hose or the solenoid itself is bad. To test remove the vacuum line and see if the line has vacuum going to it when running. If so replace the solenoid. If the vehicle has a electronic dash control to engage the 4 wheel drive the switch has been known to go bad. The best way to test is to see if there is voltage at the switch and to see if the voltage changes when the switch is activated. If there is no change in voltage when activated the switch is bad.

SOURCE: 1998 GMC Jimmy hood release cable broken

Remove the cable from the latch and any hold downs or clamps. Push the rubber gromet through the fire wall into the car. Remove the handel assy. and pull
the cable assy.out through the fire wall. Now, if the
gromet can be removed. You can decide if you wan't
to put it back from under the dash, or under the hood.
Whatever is easiest for you, but if it can't, it has to go
back from under the dash. Hope this helps.
Good luck.

On my 1995 Gmc Jimmy i have the indash switch which i bought from a dealer. I checked accuator and cable. Cable was stuck but i freed it up. I had four hi working for about a day now it blinks and goe


Still sounds like a vacuum problem - not enough vacuum to hold the solenoid in. You could try directly applying a good vacuum source (either connecting to a good line on the truck or using a vacuum pump) to see if the solenoid is working properly. If that works, you will need to recheck ALL vacuum lines. You could also check for DTCs to see if it might be a computer problem.

Four wheel drive


Try engaging the 4wd H when the vehicle is rolling slowly and in gear . Sometimes if the unit is actuated the gears will not line up an get stuck on the end of each other and will not mesh. If the gears are turning this is unlikely to occur and meshing is easier.. have the actuator checked (part that actually does the changing) and check the wiring or vacuum hoses if any used as there may be a leak or wiring /connector problem ( water /moisture/ dirty pins etc)

2000 GMC Jimmy 4x4 Switch not working and Shifting hard between 1st and 2nd


Change the switch itself if it drives normal then randomally kicks into 4 lo/4 hi i had the same problem and a transmission shop told me it was the vaccum and the transfer case but one of my mechanic friends told me that it was my switch and shops only tell you other things for the money. Try changing the switch.

The front wheels on my 2000 gmc jimmy will not lock in 4hi or 4lo


In addition to transfer case engagement via an actuator on the "T" case there is a front axle actuator. On my Blazer which I'd bet is very similar.. There was a vacuum diaphragm under the battery which operated a cable to "lock in" front axle. make sure you have vacuum supply when asking for 4 wheel operation and make sure cable is not seized. If this checks out o.k. back to transfer case. your question asked about front wheels locking so I assumed your "T"case was working

What can i do to fix the 4x4 the light just comes on but it will not lock into 4 hi of 4lo it is a 1995 gmc jimmy


Pull out the battery and the tray it sits it. Underneath is a round vacuum servo with a hose that is supposed to connect. Check to make sure the hose is connected and if not just connect it and put all back together.

I have a 1998 GMC jimmy the motor on the transfer case for putting it in to 4x4 needs to be replaced is there anything I need to know to replace it


yes
the gears inside the motor strip out because the
clutch pack inside the transfer case are hanging up
do to wear
so be carefull
you may damage the gears in the new motor
the way you can tell is to take apart the old transfer case motor and look and see if the 4 small gears are
chewed up

My truck is stuck in 4LO and it won't come out of 4LO.


Likely either a shifter position sensor, transmission position sensor, or a differential position sensor. Had same issue w/ my Montero and it ended up being one of the 5 sensors on the transfer case. It was pretty tough to get to, so replaced all 5. That fixed it.

My truck is stuck in 4LO and the button in the truck dont work.


If its a push button 4x4 take it to the shop its a VERY COMMON Problem dealing with the electric.Once you pay the $400 to get it fixed get rid of the truck and settle for a Jimmy/Blazer/Bravada with a floor shift 4x4..GM had problems with the push button 4x4.DONT DRIVE YOUR TRUCK IN THE MEANTIME.YOU WILL BLOW YOUR TRANSFER CASE RIGHT OUT OF IT!
