I have a 2000 Jimmy 4wd. When I start it, the 4wd error light comes on and never turns off. I don't have any leaking fluids, any strange noises, etc. Any help would be great.

Could be many items so look thru the posts. Try a 30 min battery disconnect to reset the 4wd computer as first step. Look at the vac lines under hood for rot/breaks and replace as necessary 5/32".

I had the exact same problem with the whining noise on my 95 blazer. Problem resolved by replacing the vacuum switch on top of the transfer case. It leaks down the vacuum, which causes the front axle to partially engage and moan/whine. The vacuum switch is a very inexpensive repair.

I am experiencing the exact problem with my 95 blazer. Can you please tell me how to replace the vacuum switch. I was unsuccessful in locating instructions on alldatadiy.com for this repair. Your help is greatly appreciated.

#97 of 307 My 99 Jimmy 4WD light issues
Aug 31, 2007 (8:54 pm)
Auto 4x4 light,2H,4H and 4L lights flash in the dash often. Seems like engine will stall for a quick second then the service 4x4 light flashes on and sometimes stays on. Also noticed clicking sound from right hand lower kick panel when the 4x4 lights flash. 4x4 will engage when buttons are pushed. Have already replaced right front ABS sensor, tried other encoder motor and problems still occur-PLEASE HELP!

#100 of 307 1997 Jimmy 4 wheel drive issue
Oct 11, 2007 (8:53 pm)
OK today i feel really stupid after months of wondering what the heck happened and why the 4 wheel drive stoped working i decided to go down the line and check the fuses well apparently fuse 19 was bad which works the 4wd switch box i guess i changed the fuse and i now see the lights light up and i can feel it kick on when i put it in 4LO
But amm wondering i had some help from a friends we lifted all 4 wheel up using 1 jack in the front and 2 jacks in the back
got all 4 wheels of the ground i wanted to just see if the 4 wheel drive works still and i dont understand how come the front wheels dont spin is it something that is just because it has to be on the ground will the Front wheels not spin or engage if the jimmy is not on the ground or is something still wrong check the vacuum lines everything seems to be fine cant think of what the problem could be please help thank you
