4 Wheel Drive/SUVs/94 Explorer

Question
I don't know if you can answer this, but I have a 94 Explorer Limited 4x4. It has push button 4x4 and the 4x4 worked fine this morning, then i went to turn it on this afternoon, and nothing. The light wouldnt turn on or anyhthing. Just nothing. So i checked the fuses under the dash and in the power distribution box and they are good, also tested them with a test light. Please help if you can. Thank you

Answer
Mindy,

I don't know where you live, but in my area (on the coast), we have a lot of corrosion problems due to the salt air.  The Explorer should have an electronic shift for the transfer case, and if the transfer case has a bad ground, it can affect the shifting.  I would check out the wiring to the transfer case, and add a ground wire from the transfer case to the frame to see if this will cure the problem.  If that doesn't fix the problem, then you may have a faulty switch, or relay.

A repair manual would be a great help.  You can purchase these at most auto parts stores for, around $20.  They are invaluable if you plan on doing any repairs, or troubleshooting yourself.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. 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

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 1 1/2" suspension lift. This gives me a total lift of 7" 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 cold air high flow 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 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. 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.
