The transfer case is no longer a simple device controlled with a single manual stick shifter.Just like the engine and trans,fuel system,exhaust system,electrical system...etc etc....It is a complex electrical world/circuit all unto itself.There are approximately 2 sensors,two switches,and an electric MOTOR and a computer,that all work in unison to provide the luxuries of "shift on the fly" transfer case abilities.As a complex electrical system,it must be diagnosed as such.Basic steps in diagnosing a problem follows in order of sequence....1:pull Diagnostic Trouble Codes (DTC)'s from the transfer case system 2:For every dtc is a diagnostic route to verify all the electrical sensors and controls and COMMANDS are in place anf functioning. 3: If all external electrical componenets are tested and verified functioning,the last diagnosis is 4: Internal transfer case failure.

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

There are two parts to it, a voltage resistor, and the EL panel itself.
You need to remove the console first. There are 2 screws under the front rubber pad, two under the cup holder, two in the bin. Remove those six first, take the storage bin out, then slide the rear cupholder out, remove the two screws under the cup holder, and one in front of it.
There are a total of 6 flat screws, and 3 self tapping screws you have removed.
Put the parking brake on, shift the tranny to N, and the transfer case to the middle position if equipped.
Remove the entire console. Slide the shifter beezel as far up vertically as you can. There are 4 clips you ned to remove to do it.
You will see a blue and black wire running into the back. Follow those wires to the resistor. You will see a transparent EL panel attatched to the resistor by two clips.
Usually, one or both of these clips has come loose, causing the light to work intermittantly. Clip them back on, and turn on the headlights to confirm that the light works correctly now.
Re-install everything in the opposite order.

check all the fuses before you do anything else. After all a fuse provides power to the electronic box that controls the transmission. Other than that I would not advice on a more complicated troubleshooting since there is no way for you to test a bad transmission computer, even mechanic shops don't know how to test them. The only thing they would do is slap a known good one and see what happens.
