there are specific tests you can run before changing parts...You should show an open circuit with no resistance between b&c connector pins on the crank sensor. (check with ohmeter) You also need to check that you have fuel /spark and test related items. (cps can kill both)

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.
