can't find any thing in my manual relating
to a switch or sensor for the 4x4 light.
have never had my console apart to see
if a switch exists on the lever itself.

call around maybe someone can give you info over the phone

cheers: eric

First, make sure that the front passenger wheel is uncoupled from the inner axle shaft by jacking up that wheel when your Jeep is in 2wd and turning it by hand. If the driveshaft turns, then the inner and outer shafts are coupled which, of course, is wrong.

You either have a problem with your vacuum shift motor or the vacuum lines or the vacuum switch on your transfer case.

There are two versions of the vacuum shift motor so I don't recall the differences. I do know, however, that some of them have an electric switch to confirm that the coupler is coupling. If the driveshaft doesn't turn, then the electric switch in the vacuum shift motor is probably faulty. You do have electrical wires going to the shift motor, don't you? If not, then there is probably a sensor on your vacuum switch on the transfer case.

Remember, XJs don't have the front axle disconnects (may be wrong here...I know the SelecTrac ones don't but I can never remember about the CommandTrac ones) so that's why an XJ manual may not mention the coupler verification switch.

CHeck the firewall on the passengers side. If there is a little blue battery looking thingy there that is the dash light vaccum sensor. It may be plugged or just stuck. Check it out.

xj's do have the vacuum disconect, not all of them though. mine does, I pulled the vacuum lines for it out and ran them into the cab so I can control the axle myself(2low is nice).
just put the tcase in 2wd and try turning the front shaft. if it turns freely then no worries other than an annoying light. if it dosn't turn then its a prob

if the front shaft is not turning try pushing on the tcase linkage while your under there to make sure it is completly in 2wd, the linkage bushings may be worn enough giving enough slop to not completly disengage 4wd
