One Green 4x4 Light, Have I got 1 wheel drive??? :) Options

[davieh]

Recently, I've had none of the 4x4 lights working. Then randomly, one of the rear wheel green lights has come on, but not the other. I didnt engage the 4x4 or do anything abnormal for this to happen. I'm confident that my car is not disobeying the laws of physics and suddenly driving through one wheel.

I have since cycled through the 4x4 positions, and all of the orange diff lights come on, but no sign of the green ones. The car is physically getting into 4WD and Low range mechanically though.

Is there any instance when I should have no 4x4 green lights on, or are the rears always lit? At ignition, I get a flash of the centre diff light, but only the single rear green.


Any thoughts on my theories?:

1) Loose connection somewhere that blocked out the 2 rear green lights that should be constantly on + a blown bulb for the rear green that is not on
2) Problem with the box under the radio
3) Problem with a sensor under the car
4) Dodgy 4x4 ECU
5) Aliens

mmhhhhh....
ur 4wd should turn on automatically when there is no tracktion...
depends on what kind and model of 4wd it is.....
could be just that one of the lights in ur dash is broken....
cause when u have ur ignition on, both of the tires should light up....(left &right..)
otherwise i'd would be the aliens...

youre WAY overthinking this.

replace the burnt out bulb on the dash. your done.

Dash lights are loose. Almost all of mine needed some tightning up to make good electrical contact.

I have the same problem ,how easy is it to replace the bulb/tighten them up in the dash ,also the fog and driving light switches ,are they supposed to be illuminated because mine arent ,I have a 2001 montero with a tiptronic auto box
