I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.
Experience Experience in the area 40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 3 1/2" suspension lift. This gives me a total lift of 9" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a K&N air filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 95:1 in low gear/low range.
Other vehicles I own, are a 95 Ford F-250 with a 6" lift, posi rear end, 35" MT's, 5 speed with a fuel injected 460 ci engine, and a stock 2000 Grand Cherokee.
Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.

Question the 4x4 switch does nothing , does not light up or engage the 4x4.the fuses in the engine compartment seem fine .what do i check next and how ? thank you
Answer Stephen,
It sounds like you may have a faulty switch, or bad wiring. The electronic module on the transfer case may be bad also.
This may not be too hard to trouble shoot yourself, if you purchase a repair manual. They can be bought at most auto parts stores for around $20, and have a full trouble shooting section. You can look this up, and see what it takes to test the control module and associated components.
Other than that, you may need to take it to a reputable transmission shop, preferably one that specializes in 4-wheel drive vehicles.
